S4MF20CA

ZHIDE · ESD And Surge Protection (TVS/ESD) · SOD-123FL

S4MF20CA from ZHIDE, in a SOD-123FL. 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 A1 passive Bidirectional TVS terminal (the C suffix marks bipolar, with no cathode band) with 20.0 V reverse stand-off voltage, 22.20 to 24.50 V breakdown at 1 mA, and 32.4 V maximum clamping at 12.3 A IPP.
2 A2 passive Bidirectional TVS terminal, interchangeable with the other terminal, with 20.0 V reverse stand-off voltage, 400 W peak pulse power (10/1000 us) and 1 uA maximum leakage at VRWM.

  • Symbol: S4MF20CA
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123FL (KiCad packages3D, STEP)
  • 3D model files: s4mf20ca-etched.step / s4mf20ca-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); s4mf20ca.step / s4mf20ca.glb are the bare package body.
