CPDT-12V-HF

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

CPDT-12V-HF from Comchip, 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 K1 passive Cathode of the first ESD protection diode (protected line); breakdown voltage 13 V min at IR = 1 mA, clamping voltage 25 V max at IPP = 1 A (8/20 us).
2 K2 passive Cathode of the second ESD protection diode (protected line); breakdown voltage 13 V min at IR = 1 mA, clamping voltage 25 V max at IPP = 1 A (8/20 us).
3 A passive Common anode of both ESD protection diodes, shared return for the two protected lines (IEC 61000-4-2 ESD capability 16 kV air, 8 kV contact).

  • Symbol: CPDT-12V-HF
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: cpdt-12v-hf-etched.step / cpdt-12v-hf-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cpdt-12v-hf.step / cpdt-12v-hf.glb are the bare package body.
