SMCJ14CA

Shandong Jingdao Microelectronics · TVS · SMC

SMCJ14CA 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 The PINNING table labels pin 1 as Cathode for the unipolar device, but the bipolar (CA) symbol is drawn without polarity, so the datasheet does not assign a distinct role to this pin for SMCJ14CA.
2 Anode passive The PINNING table labels pin 2 as Anode for the unipolar device, but the bipolar (CA) symbol is drawn without polarity, so the datasheet does not assign a distinct role to this pin for SMCJ14CA.

CAD (KiCad official)

  • Symbol: SMCJ14CA
  • Footprint: Diode_SMD:D_SMC
  • 3D model: SMC (KiCad packages3D, STEP)
  • 3D model files: smcj14ca-etched.step / smcj14ca-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smcj14ca.step / smcj14ca.glb are the bare package body.
