SSM3J372R

TOSHIBA · MOSFETs · SOT-23-3

SSM3J372R from TOSHIBA, in a SOT-23-3. 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; the absolute maximum gate-source voltage is -12/+6 V, and the device is specified for 1.8-V gate drive.
2 Source passive Source terminal; the body diode forward voltage VDSF is 1.2 V max at ID = 6.0 A and VGS = 0 V.
3 Drain passive Drain terminal; the drain-source voltage rating is -30 V and the DC drain current rating is -6.0 A.
