The BSS123-7-F is an N-channel enhancement-mode MOSFET housed in a compact SOT-23 package. It is suitable for applications such as small servo motor control, MOSFET gate driving, and low-current switching. What Is BSS123-7-F?The BSS123-7-F N-channel enhancement-mode FET manufactured by Diodes Incorporated using its proprietary high-density advanced trench technology.In terms of key electrical specifications, the BSS123-7-F features a maximum drain-source voltage (VDS) of 100V, a continuous drain current (ID) of up to 170mA, and a gate-source voltage (VGS) of ±20V. Its maximum on-state resistance (RDS(on)) is approximately 6Ω at VGS = 10V, with an operating temperature range of -55°C to +150°C. It is suitable for electronic circuits where compact size and reliable switching control are required.(Contact us for a quote) BSS123-7-F SpecificationsThis section lists the key specifications of the BSS123-7-F diode.ParameterValuePart NumberBSS123-7-FManufacturerDiodes IncorporatedInput Capacitance (Ciss) (Max) @ Vds60pF @ 25VDrive Voltage (Max Rds On, Min Rds On)10VLead Free Status / RoHS StatusLead free / RoHS CompliantPackagingTape & Reel (TR)FET TypeN-ChannelTechnologyMOSFET (Metal Oxide)Rds On (Max) @ Id, Vgs6 Ohm @ 170mA, 10VCurrent - Continuous Drain (Id) @ 25°C170mA (Ta)Drain to Source Voltage (Vdss)100VVgs (Max)±20VMounting TypeSurface MountVgs(th) (Max) @ Id2V @ 1mAPower Dissipation (Max)300mW (Ta)Operating Temperature-55°C ~ 150°C (TJ)PackageSOT-23-3Base Part NumberBSS123 BSS123-7-F Pinout The BSS123-7-F is housed in a SOT-23 package with three pins: Drain (D), Gate (G), and Source (S). The functions of each pin are as follows:l D (Drain): The drain pin connects to the load or drain-side circuit and carries the drain current.l G (Gate): The gate pin controls the MOSFET's turn-on and turn-off by applying a gate-source voltage (VGS) to control the D-S channel.l S (Source): The source pin provides the current return path and serves as the reference point for the gate-source voltage. How Does BSS123-7-F Work?The BSS123-7-F controls the conduction state between the Drain (D) and Source (S) through the voltage applied to the Gate (G). When VGS is below the gate threshold voltage, the D-S channel remains essentially off and the drain current is very small. When VGS exceeds the threshold, the electric field generated by the gate forms a conductive channel in the semiconductor, allowing current to flow from D to S.With its low-level logic triggering characteristic, the BSS123-7-F can be driven by a high-level output from a microcontroller GPIO pin, allowing the transistor to turn on quickly. When the GPIO output goes low, the conductive channel disappears and the circuit switches off rapidly, enabling high-speed electronic switching control for small signals or low-power loads.(Contact us for a quote) BSS123-7-F Features and BenefitsHere are the core features of BSS123-7-F below.l Low Gate Threshold Voltagel Low Input Capacitancel Fast Switching Speedl Low Input/Output Leakagel High Drain-Source Voltage Ratingl Totally Lead-Free & Fully RoHS Compliant l Halogen- and Antimony-Free.

Industrial Control CircuitsThe BSS123-7-F can be used for auxiliary switching, signal control, and low-power load switching in industrial control equipment, providing a simple switching solution for compact control circuits.(Contact us for a quote) BSS123-7-F vs. BSS123The BSS123-7-F and BSS123 have essentially the same core electrical performance. The main differences are in packaging and part-number suffixes.l "-7" suffix: Indicates 7-inch Tape and Reel packaging for automated SMT assembly.l "-F" suffix: Indicates a Lead-Free and RoHS-compliant version.The BSS123-7-F is therefore a lead-free, tape-and-reel version of the BSS123, with the same basic function and application. How to Test the BSS123-7-F?Testing the BSS123-7-F, an N-channel MOSFET in a SOT-23 package, usually requires a multimeter in diode or resistance mode. Confirm the pinout before testing. Step 1: Remove the DeviceDesolder the BSS123-7-F from the circuit and place it on an insulated or ESD-safe surface. In-circuit testing may be affected by other components. Step 2: Discharge the DeviceBriefly short the G, D, and S pins with metal tweezers or a wire to discharge any residual charge. Step 3: Test the Body DiodeSet the multimeter to diode mode. Connect the red probe to S and the black probe to D. A reading of about 0.4–0.9 V is expected. Reverse the probes; the meter should show OL. Step 4: Turn the MOSFET OnKeep the black probe on S and briefly touch the red probe to G to charge the gate. Then move the red probe to D. The reading should drop significantly, close to 0 V, or the buzzer may sound, indicating that the channel is conducting. Step 5: Turn the MOSFET OffKeep the red probe on D and briefly touch the black probe to G to discharge the gate. Then move it back to S. The reading should return to the original 0.4–0.9 V body-diode reading or show OL, indicating that the channel is off.

Analog ADM705ARZ Microprocessor Supervisory IC Overview
The ADM705ARZ is a low-power microprocessor supervisory IC from Analog Devices' ADM705/706/707/708 series, integrating power supply monitoring, reset, watchdog timer, manual reset, and power-fail detection functions. What Is ADM705ARZ?The ADM705ARZ is designed to monitor 5V power supplies and microprocessor activity. It belongs to the ADM705 series.Its power monitoring circuit generates a reset signal during power-up, power-down, and brownout conditions, with the reset output remaining operational down to 1V VCC. The built-in watchdog monitors microprocessor activity and can trigger an output when the watchdog input is not toggled within 1.60 seconds. A 1.25V threshold detector is also included for power-fail warning, low-battery detection, or monitoring an additional supply rail.In the ADM705 family, the main difference between ADM705 and ADM706 is the reset threshold, at 4.65V and 4.40V, respectively. The ADM705ARZ comes in an 8-lead SOIC package and is suitable for microprocessor systems, embedded controllers, and other applications requiring power and system monitoring.(Contact us for a quote) ADM705ARZ SpecificationsThis section lists the key specifications of the ADM705ARZ under defined operating conditions.ParameterValuePart NumberADM705ARZManufacturerADI (Analog Devices, Inc.)Voltage - Threshold4.65VResetActive LowTypeSimple Reset/Power-On ResetOperating Temperature-40°C ~ 85°C (TA)Mounting TypeSurface MountOutputPush-Pull, Totem PoleReset Timeout160 ms MinimumNumber of Voltages Monitored1PackagingTubePackage8-SOICBase Part NumberADM705 ADM705ARZ Pin Configuration1. MR (Manual Reset Input): Manual reset input. Pulling this pin low triggers a reset.2. VCC (Supply Voltage): Power supply input for the ADM705ARZ.3. GND (Ground): Ground connection for the device.4. PFI (Power-Fail Input): Power-fail input used to monitor an additional power supply or low-battery condition.5. PFO (Power-Fail Output): Power-fail output that indicates the status of the PFI input.6. WDI (Watchdog Input): Watchdog input that monitors activity from the microprocessor.7. RESET (Active-Low Reset Output): Active-low reset output that is triggered during power supply faults or watchdog timeout conditions.8. WDO (Watchdog Output): Watchdog output that indicates a watchdog timeout when the WDI signal is not toggled within the specified period. How Does ADM705ARZ Work?The ADM705ARZ continuously monitors the VCC supply voltage. When the voltage falls below the specified threshold during power-up, power-down, or brownout conditions, the RESET output is pulled low, keeping the microprocessor in or placing it into reset. Once the supply returns to a normal level, the system resumes operation after the specified reset delay.The ADM705ARZ also features an independent watchdog timer that monitors microprocessor activity through the WDI pin. If the WDI signal is not toggled within 1.60 seconds, the watchdog triggers the corresponding WDO output.(Contact us for a quote) ADM705ARZ Functional Block Diagram ADM705ARZ Featuresl Guaranteed RESET valid with VCC = 1 Vl 190 μA quiescent currentl Precision supply voltage monitor 4.65 Vl 200 ms reset pulse widthl Debounced TTL/CMOS manual reset input (MR)l Independent watchdog timer l 1.60 sec timeoutl Voltage monitor for power fail or low battery warningl Superior upgrade for MAX705 to MAX708 ADM705ARZ ApplicationsThe ADM705ARZ provides power and operating status monitoring for various microprocessor-based systems and is suitable for the following applications: 1.

The main difference between each pair is the reset threshold: 4.65 V for ADM705/ADM707 and 4.40 V for ADM706/ADM708. Which ADM70x Device Should You Choose?When choosing an ADM70x device, the main factors are the reset threshold and watchdog requirements. For systems that need watchdog monitoring, choose the ADM705 or ADM706. The ADM705 has a 4.65 V reset threshold, while the ADM706 has a 4.40 V threshold. If a watchdog is not required but both active-high and active-low reset outputs are needed, the ADM707 or ADM708 can be considered, with reset thresholds of 4.65 V and 4.40 V, respectively.For common 5 V microprocessor systems that require power monitoring, reset control, and watchdog functions, the ADM705 is a suitable choice. The ADM706 may be preferred when a lower reset threshold is needed. Final selection should also consider the system supply voltage, reset logic, and MCU interface requirements.
