SMF40CA

AnBon · ESD And Surge Protection (TVS/ESD) · SOD-123

SMF40CA from AnBon, in a SOD-123. 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 Bi-directional TVS terminal on the left end of the SOD-123 outline (no cathode band on the C-suffix part); the datasheet gives no pin label for the bi-directional device, so this is the left-hand terminal and is interchangeable with pin 2.
2 A2 passive Bi-directional TVS terminal on the right end of the SOD-123 outline (no cathode band on the C-suffix part); the datasheet gives no pin label for the bi-directional device, so this is the right-hand terminal and is interchangeable with pin 1.

  • Symbol: SMF40CA
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: smf40ca-etched.step / smf40ca-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smf40ca.step / smf40ca.glb are the bare package body.

Provenance

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

  • Datasheet: AnBon datasheet (4 pp, sha256 446f2844d4bbca04, retrieved 2026-10-09, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (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).
