SMDJ180A

Liown · ESD And Surge Protection (TVS/ESD) · SMC(DO-214AB)

SMDJ180A from Liown, in a SMC(DO-214AB). 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 Cathode passive Cathode terminal of the unidirectional SMDJ180A (marked by the cathode band on the package), connected to the protected line, with 180V reverse stand-off voltage and 201-222V breakdown at 1mA.
2 Anode passive Anode terminal of the unidirectional SMDJ180A, normally returned to ground, with the cathode clamping at 292V maximum at 10.3A peak pulse current.

CAD (KiCad official)

  • Symbol: SMDJ180A
  • Footprint: Diode_SMD:D_SMC
  • 3D model: SMC(DO-214AB) (KiCad packages3D, STEP)
  • 3D model files: smdj180a-etched.step / smdj180a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smdj180a.step / smdj180a.glb are the bare package body.
