SMAJ170A-13-F

Diodes Incorporated · TVS · SMA

SMAJ170A-13-F from Diodes Incorporated, in a SMA. 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 terminal, identified by the cathode band on the unidirectional SMAJ170A, which has a 170V reverse standoff voltage and 275V maximum clamping voltage at 1.4A.
2 A passive Anode terminal at the end opposite the cathode band of the unidirectional SMAJ170A, with a 400W peak pulse power rating.

CAD (KiCad official)

  • Symbol: SMAJ170A-13-F
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA (KiCad packages3D, STEP)
  • 3D model files: smaj170a-13-f-etched.step / smaj170a-13-f-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smaj170a-13-f.step / smaj170a-13-f.glb are the bare package body.
