STPS4S200B-TR

STMicroelectronics · Schottky Diodes · DPAK

STPS4S200B-TR from STMicroelectronics, in a DPAK. 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 A passive Anode of the 200 V, 4 A Schottky rectifier.
2 K passive Cathode, connected to the exposed tab (thermal pad) of the DPAK; the 3D view labels it K.
3 NC unconnected No connection; the DPAK lead is labelled NC in the device picture.

CAD (KiCad official)

  • Symbol: STPS4S200B-TR
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: DPAK (KiCad packages3D, STEP)
  • 3D model files: stps4s200b-tr-etched.step / stps4s200b-tr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); stps4s200b-tr.step / stps4s200b-tr.glb are the bare package body.

Provenance

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

  • Datasheet: STMicroelectronics datasheet (12 pp, sha256 2d717ac7bfd879a6, retrieved 2026-10-21, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
