SMCJ170A

Shandong Jingdao Microelectronics · TVS · SMC

SMCJ170A from Shandong Jingdao Microelectronics, in a SMC. 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, identified as pin 1 in the PINNING table for the Unipolar symbol, which applies to the unidirectional SMCJ170A (listed in the UNI column of the Characteristics table).
2 Anode passive Anode terminal, identified as pin 2 in the PINNING table for the Unipolar symbol, which applies to the unidirectional SMCJ170A.

CAD (KiCad official)

  • Symbol: SMCJ170A
  • Footprint: Diode_SMD:D_SMC
  • 3D model: SMC (KiCad packages3D, STEP)
  • 3D model files: smcj170a-etched.step / smcj170a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smcj170a.step / smcj170a.glb are the bare package body.
