# 40P04

**HL** · MOSFETs · TO-252

40P04 from HL, in a TO-252. 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; gate-source voltage rated ±20 V, threshold -1 to -2.2 V at ID = -250µA. |
| 2 | D | passive | Drain, also connected to the exposed tab; drain-source voltage -40 V, continuous drain current -40 A at TC = 25°C. |
| 3 | S | passive | Source of the P-channel MOSFET; body diode continuous source current -40 A. |

## CAD (KiCad official)

- Symbol: `40P04`
- Footprint: `Package_TO_SOT_SMD:TO-252-2`
- 3D model: TO-252 (KiCad packages3D, STEP)
- 3D model files: `40p04-etched.step` / `40p04-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `40p04.step` / `40p04.glb` are the bare package body.
