# IRFPE50-JSM

**JSMSEMI** · MOSFETs · TO-247

IRFPE50-JSM from JSMSEMI, in a TO-247. 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 is rated at ±20 V continuous, with a gate threshold of 2 V to 4 V at VDS=VGS and ID=0.25 mA. |
| 2 | D | passive | Drain; drain-source voltage is rated at 800 V, with continuous drain current of 7.8 A and pulsed drain current of 31 A. |
| 3 | S | passive | Source; the source terminal of the N-channel MOSFET, carrying the 7.8 A continuous drain current return path. |

## CAD (KiCad official)

- Symbol: `IRFPE50-JSM`
- Footprint: `Package_TO_SOT_THT:TO-247-3_Vertical`
- 3D model: TO-247 (KiCad packages3D, STEP)
- 3D model files: `irfpe50-jsm-etched.step` / `irfpe50-jsm-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `irfpe50-jsm.step` / `irfpe50-jsm.glb` are the bare package body.
