Specifications:

The SSM3J327R typically features a drain-source voltage (VDS) of -30V and a continuous drain current (ID) of -1.8A. The on-resistance (RDS(on)) is typically around 0.15 ohms at a gate-source voltage (VGS) of -4.5V. The gate threshold voltage (VGS(th)) is typically around -1.5V. For precise electrical characteristics, thermal specifications, and recommended operating conditions, consult the official datasheet provided by Toshiba Semiconductor and Storage.

The SOT-23F package is designed for surface mount assembly. Proper thermal management is essential to ensure reliable operation, especially at higher currents and ambient temperatures. The device is sensitive to electrostatic discharge (ESD) and should be handled with appropriate precautions during assembly and testing.
