PJM3401PSC from PJSEMI, 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, with gate-source voltage rated at ±12 V (VGS). |
| 2 | Source | passive | Source terminal of the MOSFET; the datasheet gives no pin-specific limit, only device ratings of -VDS 30 V and continuous -ID 4.5 A. |
| 3 | Drain | passive | Drain terminal of the MOSFET, rated for drain-source voltage of -30 V (VDS) with continuous drain current of 4.5 A. |
