STPS20S100CT

STMicroelectronics · Schottky Diodes · TO-220

STPS20S100CT from STMicroelectronics, 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 A1 input Anode 1 of rectifier; forward RMS current rating 30 A per diode at Tc = 150°C, forward voltage drop maximum 0.80 V at IF = 20 A and Tj = 125°C.
2 K power_in Common cathode; 100 V repetitive peak reverse voltage rating, 30 A RMS forward current per diode, provides current return path for both anodes.
3 A2 input Anode 2 of rectifier; forward RMS current rating 30 A per diode at Tc = 150°C, forward voltage drop maximum 0.80 V at IF = 20 A and Tj = 125°C.

  • Symbol: STPS20S100CT
  • Footprint: Package_TO_SOT_THT:TO-220-3_Vertical
  • 3D model: TO-220 (KiCad packages3D, STEP)
  • 3D model files: stps20s100ct-etched.step / stps20s100ct-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); stps20s100ct.step / stps20s100ct.glb are the bare package body.

Provenance

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