SM12-02HTG

UMW · ESD And Surge Protection (TVS/ESD) · SOT-23

SM12-02HTG from UMW, in a SOT-23. 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 I/O1 bidirectional Bidirectional TVS protection line rated for a 12V working voltage, clamping to Pin 3 with ±30kV contact and air ESD withstand per IEC 61000-4-2.
2 I/O2 bidirectional Bidirectional TVS protection line rated for a 12V working voltage, clamping to Pin 3 with ±30kV contact and air ESD withstand per IEC 61000-4-2.
3 GND power_in Common reference pin to which Pin 1 and Pin 2 clamp during surge and ESD events.

CAD (KiCad official)

  • Symbol: SM12-02HTG
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: sm12-02htg-etched.step / sm12-02htg-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sm12-02htg.step / sm12-02htg.glb are the bare package body.

Provenance

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

  • Datasheet: UMW datasheet (11 pp, sha256 0e09b07cb6bbf5ef, retrieved 2026-11-05, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-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).
