S-SM340C

LRC · Schottky Diodes · SMC

S-SM340C from LRC, in a SMC. 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 K passive Cathode terminal; the datasheet shows the diode symbol with the cathode on the bar side, and the part is rated for 40V repetitive peak reverse voltage and 3A average forward current.
2 A passive Anode terminal; the part has a maximum forward voltage of 0.55V at 3.0A and a peak forward surge current of 140A (8.3ms half sine-wave).

  • Symbol: S-SM340C
  • Footprint: Diode_SMD:D_SMC
  • 3D model: SMC (KiCad packages3D, STEP)
  • 3D model files: s-sm340c-etched.step / s-sm340c-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); s-sm340c.step / s-sm340c.glb are the bare package body.

Provenance

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

  • Datasheet: LRC datasheet (3 pp, sha256 1d105162b3cfa967, retrieved 2026-10-13, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (text+vision), consensus claude-opus-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
