# FDP20N50F

**onsemi** · MOSFETs · TO-220

FDP20N50F from onsemi, in a TO-220. 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-to-source voltage limited to ±30 V (VGSS). |
| 2 | D | passive | Drain, also connected to the mounting tab; 500 V drain-to-source voltage (VDSS) and 20 A continuous drain current at TC = 25°C. |
| 3 | S | passive | Source; source of the N-channel MOSFET with its body diode connected to the drain. |

## CAD (KiCad official)

- Symbol: `FDP20N50F`
- Footprint: `Package_TO_SOT_THT:TO-220-3_Vertical`
- 3D model: TO-220 (KiCad packages3D, STEP)
- 3D model files: `fdp20n50f-etched.step` / `fdp20n50f-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `fdp20n50f.step` / `fdp20n50f.glb` are the bare package body.
