SSM3K347R

TOSHIBA · MOSFETs · SOT-23F

SSM3K347R from TOSHIBA, in a SOT-23F. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 Gate input Gate terminal of the N-channel MOSFET, driven at 4.0 V to 10 V for the stated RDS(ON) ratings; the datasheet states a built-in 47 kΩ pull-down resistance (Rpd) on this device.
2 Source passive Source terminal of the N-channel MOSFET, serving as the reference for the gate-source voltage (VGSS rated ±20 V on the absolute maximum table).
3 Drain passive Drain terminal of the N-channel MOSFET, rated at a drain-source voltage VDS(DC) of 38 V on the absolute maximum table.
