STPS40L45CW

STMicroelectronics · Schottky Diodes · TO-247-3

STPS40L45CW from STMicroelectronics, in a TO-247-3. 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 power_in Anode 1 of dual center tap rectifier; IF(AV) 20 A per diode (Tc 130°C), VRRM 45 V, VF(max) 0.49 V (Tj 125°C)
2 K power_out Common cathode connecting both diodes; IF(AV) 40 A total, Tj(max) 150°C
3 A2 power_in Anode 2 of dual center tap rectifier; IF(AV) 20 A per diode (Tc 130°C), VRRM 45 V, VF(max) 0.49 V (Tj 125°C)

CAD (KiCad official)

  • Symbol: STPS40L45CW
  • Footprint: Package_TO_SOT_THT:TO-247-3_Vertical
  • 3D model: TO-247-3 (KiCad packages3D, STEP)
  • 3D model files: stps40l45cw-etched.step / stps40l45cw-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); stps40l45cw.step / stps40l45cw.glb are the bare package body.

Provenance

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

  • Datasheet: STMicroelectronics datasheet (11 pp, sha256 f87f87a650625dbf, retrieved 2026-09-24, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.2, primary claude-haiku-4-5-20251001 (text), consensus claude-sonnet-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
