TPSMF18A

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

TPSMF18A from TECH PUBLIC, 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 K passive Cathode of the uni-directional TPSMF18A TVS diode (18 V reverse stand-off, 20 V to 22.1 V breakdown at 1 mA, 29.2 V max clamping at 6.8 A IPP).
2 A passive Anode of the uni-directional TPSMF18A TVS diode, normally tied to the protected return or ground side.

  • Symbol: TPSMF18A
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123FL (KiCad packages3D, STEP)
  • 3D model files: tpsmf18a-etched.step / tpsmf18a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tpsmf18a.step / tpsmf18a.glb are the bare package body.
