STB20NM50T4

STMicroelectronics · MOSFETs · TO-263

STB20NM50T4 from STMicroelectronics, in a TO-263. 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 of the N-channel MOSFET; gate-source voltage is rated at ±30 V (VGS, Table 1).
2 D passive Drain of the N-channel MOSFET; drain-source voltage is rated at 500 V (VDS, Table 1).
3 S passive Source of the N-channel MOSFET; continuous drain current is rated at 20 A at TC = 25 °C (ID, Table 1).

CAD (KiCad official)

  • Symbol: STB20NM50T4
  • Footprint: Package_TO_SOT_SMD:TO-263-2
  • 3D model: TO-263 (KiCad packages3D, STEP)
  • 3D model files: stb20nm50t4-etched.step / stb20nm50t4-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); stb20nm50t4.step / stb20nm50t4.glb are the bare package body.
