SSM3J328R 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 P-channel MOSFET; gate-source voltage is rated ±8 V (VGSS), and the datasheet notes VGS(off) must stay below Vth (-0.3 V to -1.0 V) for normal switching. |
| 2 | Source | passive | Source terminal of the P-channel MOSFET; the device is rated for a drain-source voltage of -20 V (VDSS) with a DC drain current of -6.0 A. |
| 3 | Drain | passive | Drain terminal of the P-channel MOSFET; the device is rated for a drain-source voltage of -20 V (VDSS) and a DC drain current of -6.0 A, with a channel temperature not to exceed 150 °C. |
