WSR20N20

Winsok Semicon · MOSFETs · TO-220

WSR20N20 from Winsok Semicon, 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-source voltage is rated at ±20 V maximum, with a threshold of 2.0 V min to 4.0 V max at ID=250uA.
2 D passive Drain, connected to the mounting tab; drain-source voltage is rated at 200 V and continuous drain current at 20 A (TC=25℃).
3 S passive Source; continuous body-diode source current is 18 A and pulsed source current is 72 A.

CAD (KiCad official)

  • Symbol: WSR20N20
  • Footprint: Package_TO_SOT_THT:TO-220-3_Vertical
  • 3D model: TO-220 (KiCad packages3D, STEP)
  • 3D model files: wsr20n20-etched.step / wsr20n20-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); wsr20n20.step / wsr20n20.glb are the bare package body.
