SMF22CA

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

SMF22CA from LGE, in a SOD-123. 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 1 (SMF22CA, 22 V working voltage, 200 W peak pulse power at 10/1000 μs); the device is symmetric and has no cathode band.
2 A2 passive Bidirectional TVS terminal 2 (SMF22CA, 22 V working voltage, 200 W peak pulse power at 10/1000 μs); the device is symmetric and has no cathode band.

CAD (KiCad official)

  • Symbol: SMF22CA
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: smf22ca-etched.step / smf22ca-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smf22ca.step / smf22ca.glb are the bare package body.
