SMCJ28CA-L

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

SMCJ28CA-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 1 passive Terminal 1 of the bipolar SMC TVS (listed as Cathode in the pinning table for the unipolar type); SMCJ28CA-L has 28 V reverse stand-off, 31.1-34.4 V breakdown at 1 mA, and 45.4 V max clamping at 13.3 A.
2 2 passive Terminal 2 of the bipolar SMC TVS (listed as Anode in the pinning table for the unipolar type); SMCJ28CA-L has 28 V reverse stand-off, 31.1-34.4 V breakdown at 1 mA, and 45.4 V max clamping at 13.3 A.

CAD (KiCad official)

  • Symbol: SMCJ28CA-L
  • Footprint: Diode_SMD:D_SMC
  • 3D model: SMC (KiCad packages3D, STEP)
  • 3D model files: smcj28ca-l-etched.step / smcj28ca-l-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smcj28ca-l.step / smcj28ca-l.glb are the bare package body.
