SB2045L

MSKSEMI · Schottky Barrier Diodes (SBD) · TO-277

SB2045L from MSKSEMI, in a TO-277. 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 passive Anode lead, one of two small anode leads tied together on the symbol with PIN 3; the datasheet's anode pad is 5.6mm x 14.4mm for the thermal-resistance test.
2 K passive Cathode, the large exposed pad (cathode pad 18.8mm x 14.4mm in the thermal-resistance test), marked by the cathode band.
3 A2 passive Anode lead, tied to PIN 1 on the symbol; the two anode leads together carry the 20.0A maximum average forward current.

  • Symbol: SB2045L
  • Footprint: Package_TO_SOT_SMD:TO-277A
  • 3D model: TO-277 (KiCad packages3D, STEP)
  • 3D model files: sb2045l-etched.step / sb2045l-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sb2045l.step / sb2045l.glb are the bare package body.

Provenance

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

  • Datasheet: MSKSEMI datasheet (5 pp, sha256 336f86a8b792f54a, retrieved 2026-10-22, 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).
