# IRF4905STRL

**UMW** · MOSFETs · TO-252

IRF4905STRL from UMW, 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 terminal; the datasheet gives a gate-to-source voltage rating of ±20 V. |
| 2 | D | passive | DRAIN terminal; rated for VDS of -55 V and continuous drain current of -70 A at TC=25°C (silicon limited). |
| 3 | S | passive | SOURCE terminal; the body-diode continuous source current IS is rated at -42 A. |

## CAD (KiCad official)

- Symbol: `IRF4905STRL`
- Footprint: `Package_TO_SOT_SMD:TO-252-2`
- 3D model: TO-252 (KiCad packages3D, STEP)
- 3D model files: `irf4905strl-etched.step` / `irf4905strl-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `irf4905strl.step` / `irf4905strl.glb` are the bare package body.
