SM15-02HTG

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

SM15-02HTG 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 Protected signal line that is clamped to pin 3 by the SM15 TVS array, rated for ±30 kV contact and air ESD per IEC 61000-4-2 and 50 A EFT per IEC 61000-4-4 (5/50 ns).
2 I/O2 bidirectional Protected signal line that is clamped to pin 3 by the SM15 TVS array, rated for ±30 kV contact and air ESD per IEC 61000-4-2 and 50 A EFT per IEC 61000-4-4 (5/50 ns).
3 GND power_in Common reference terminal to which pins 1 and 2 are clamped; the electrical tables test I/O-to-GND and 'Pin 1 or Pin 2 to Pin 3' conditions.

CAD (KiCad official)

  • Symbol: SM15-02HTG
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: sm15-02htg-etched.step / sm15-02htg-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sm15-02htg.step / sm15-02htg.glb are the bare package body.
