SM15C

MDD Microdiode Semiconductor · ESD And Surge Protection (TVS/ESD) · SOT-23

SM15C from MDD Microdiode Semiconductor, 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 passive Protected line 1, a bidirectional TVS to pin 3 with VRWM 15 V, VB 16.7 V min at 1 mA, and IEC 61000-4-2 ESD rating of ±30 kV (air and contact).
2 I/O2 passive Protected line 2, a bidirectional TVS to pin 3 with VRWM 15 V, VB 16.7 V min at 1 mA, and IEC 61000-4-2 ESD rating of ±30 kV (air and contact).
3 COMMON passive Common node shared by both bidirectional TVS diodes, which the circuit diagram shows joined at pin 3 and which has no polarity.

  • Symbol: SM15C
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: sm15c-etched.step / sm15c-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sm15c.step / sm15c.glb are the bare package body.
