PJM84PSA 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; gate-source voltage is rated at ±20 V. |
| 2 | Source | passive | Source terminal of the P-channel MOSFET; the device is rated for a drain-source voltage of -50 V and continuous drain current of -0.13 A. |
| 3 | Drain | passive | Drain terminal of the P-channel MOSFET; continuous drain current is -0.13 A and pulsed drain current is -0.52 A (tp < 10 µs). |
