# PJM05P40SA

**PJSEMI** · MOSFETs · SOT-23

PJM05P40SA 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 VGS rated at ±20 V. |
| 2 | Source | passive | Source terminal of the P-channel MOSFET; the datasheet rates source-drain diode forward current at -IS = 5 A maximum. |
| 3 | Drain | passive | Drain terminal of the P-channel MOSFET, rated for a drain-source voltage of -VDS = 40 V and continuous drain current of -ID = 5 A. |

## CAD (KiCad official)

- Symbol: `PJM05P40SA`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `pjm05p40sa-etched.step` / `pjm05p40sa-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `pjm05p40sa.step` / `pjm05p40sa.glb` are the bare package body.
