1.5SMC33CAHE3

Vishay Intertech · TVS · SMC

1.5SMC33CAHE3 from Vishay Intertech, 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 A1 passive Bi-directional TVS terminal with no polarity marking, electrical characteristics apply in both directions (VWM 28.2 V, VBR 31.4 to 34.7 V for the 33CA type).
2 A2 passive Second bi-directional TVS terminal with no polarity marking and no cathode band, interchangeable with the other terminal (1500 W peak pulse power, 10/1000 μs).

CAD (KiCad official)

  • Symbol: 1.5SMC33CAHE3
  • Footprint: Diode_SMD:D_SMC
  • 3D model: SMC (KiCad packages3D, STEP)
  • 3D model files: 1-5smc33cahe3-etched.step / 1-5smc33cahe3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 1-5smc33cahe3.step / 1-5smc33cahe3.glb are the bare package body.

Provenance

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

  • Datasheet: Vishay Intertech datasheet (5 pp, sha256 adc3cc0fe70b1d3f, retrieved 2026-10-31, tier: manufacturer)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (text), consensus claude-sonnet-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).
