SSM3J325F

TOSHIBA · MOSFETs · SOT-23

SSM3J325F from TOSHIBA, in a SOT-23. 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 P-channel MOSFET; the gate-source voltage is rated VGSS = ±8 V (absolute maximum).
2 Source passive Source terminal of the P-channel MOSFET; the drain-source voltage is rated VDSS = -20 V (absolute maximum).
3 Drain passive Drain terminal of the P-channel MOSFET; the DC drain current is rated ID = -2.0 A and the pulsed drain current IDP = -4.0 A (absolute maximum, Note 1).
