SSM3K333R

TOSHIBA · MOSFETs · SOT-23F

SSM3K333R 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, rated for a gate-source voltage VGSS of ±20 V, with gate threshold voltage Vth of 1.3 V to 2.5 V at VDS = 10 V and ID = 0.1 mA.
2 Source passive Source terminal, the reference for the gate-source voltage rating (VGSS ±20 V) and the device is rated for a drain-source voltage VDSS of 30 V.
3 Drain passive Drain terminal, rated for a drain-source voltage VDSS of 30 V and a DC drain current ID of 6 A (pulse 12 A), with channel temperature not to exceed 150 °C.
