SMCJ30CA-L

Shandong Jingdao Microelectronics · ESD And Surge Protection (TVS/ESD) · SMC

SMCJ30CA-L 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 per the PINNING table, which labels pin 1 as Cathode for the unipolar symbol; the datasheet gives no polarity designation for the bipolar (CA) variant this MPN belongs to.
2 Anode passive Anode terminal per the PINNING table, which labels pin 2 as Anode for the unipolar symbol; the datasheet gives no polarity designation for the bipolar (CA) variant this MPN belongs to.

CAD (KiCad official)

  • Symbol: SMCJ30CA-L
  • Footprint: Diode_SMD:D_SMC
  • 3D model: SMC (KiCad packages3D, STEP)
  • 3D model files: smcj30ca-l-etched.step / smcj30ca-l-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smcj30ca-l.step / smcj30ca-l.glb are the bare package body.
