SMCJ43CA-L

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

SMCJ43CA-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 The datasheet's pinning table labels pin 1 as Cathode for the unipolar devices, and the bipolar (CA) symbol shows no polarity for this terminal, so it is interchangeable with pin 2 for the SMCJ43CA-L.
2 Anode passive The datasheet's pinning table labels pin 2 as Anode for the unipolar devices, and the bipolar (CA) symbol shows no polarity for this terminal, so it is interchangeable with pin 1 for the SMCJ43CA-L.

CAD (KiCad official)

  • Symbol: SMCJ43CA-L
  • Footprint: Diode_SMD:D_SMC
  • 3D model: SMC (KiCad packages3D, STEP)
  • 3D model files: smcj43ca-l-etched.step / smcj43ca-l-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smcj43ca-l.step / smcj43ca-l.glb are the bare package body.
