SM15

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

SM15 from Wild Goose, 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 CATHODE1 passive Cathode of the first unidirectional transil diode; reverse working voltage VRWM is 15 V max, with breakdown voltage 16.5 V at IT = 1 mA.
2 CATHODE2 passive Cathode of the second unidirectional transil diode; shares the same 15 V reverse working voltage and 16.5 V breakdown ratings as pin 1.
3 COMMON_ANODE passive Common anode shared by both diodes; junction capacitance is specified from pin 1 or pin 2 to pin 3 at VR = 0 V, 1 MHz.

CAD (KiCad official)

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