STPS1045B-TR

STMicroelectronics · Schottky Diodes · TO-252-2(DPAK)

STPS1045B-TR from STMicroelectronics, in a TO-252-2(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 lead of the Schottky rectifier; carries the forward current (IF(AV) = 10 A average at Tc = 150 °C, δ = 0.5; IF(RMS) = 7 A per pin; IFSM = 75 A for 10 ms surge) with typical forward voltage drop VF = 0.50 V at IF = 10 A, Tj = 125 °C.
2 A passive Second anode lead, internally tied to pin 1 (both anodes of the single die), sharing the same forward-current and forward-voltage ratings given for the anode.
3 K passive Cathode, formed by the exposed metal tab/heatsink of the DPAK package; rated for VRRM = 45 V repetitive peak reverse voltage, with IR ≤ 100 µA at Tj = 25 °C (≤15 mA at Tj = 125 °C) at VR = VRRM, and provides the thermal path to case (Rth(j-c) = 3 °C/W max).

CAD (KiCad official)

  • Symbol: STPS1045B-TR
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: TO-252-2(DPAK) (KiCad packages3D, STEP)
  • 3D model files: stps1045b-tr-etched.step / stps1045b-tr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); stps1045b-tr.step / stps1045b-tr.glb are the bare package body.

Provenance

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

  • Datasheet: STMicroelectronics datasheet (8 pp, sha256 be86722cfa401254, retrieved 2026-09-29, 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).
