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.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: onsemi datasheet (12 pp, sha256 240b0b93ad769143, retrieved 2026-10-19, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (vision), consensus claude-opus-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
