**Shanghai Prisemi Elec** · MOSFETs · SOT-23

PPMT20V3 from Shanghai Prisemi Elec, 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 | G | input | Gate terminal; the absolute maximum gate-source voltage is ±8 V and the gate threshold voltage is -0.45 V to -0.9 V. |
| 2 | S | passive | Source terminal of the P-channel MOSFET, serving as the reference for VGS; the datasheet gives no source-specific rating. |
| 3 | D | passive | Drain terminal; the absolute maximum drain-source voltage is -20 V and the continuous drain current is -2.8 A. |
