5KASMC33AHM3_A

Public Made by Adom

by adom

Vishay Intertech TVS, SMC(DO-214AB). Unpolarised two-terminal part: the datasheet prints no pin numbers, so pins 1 and 2 follow the library convention, KiCad symbol/footprint/3D.

CAD (KiCad official)

  • Symbol: 5KASMC33AHM3_A
  • Footprint: Diode_SMD:D_SMC
  • 3D model: SMC(DO-214AB) (KiCad packages3D, STEP)
  • 3D model files: 5kasmc33ahm3-a-etched.step / 5kasmc33ahm3-a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 5kasmc33ahm3-a.step / 5kasmc33ahm3-a.glb are the bare package body.

Provenance

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

  • Datasheet: Vishay Intertech datasheet (5 pp, sha256 190b00ad9af109c0, retrieved 2026-11-02, tier: manufacturer)
  • Extractor: parts-factory 2.0.0 / extract_pins, primary cathode-band convention (convention), consensus off (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).
