SMCJ11A

JUXING · Electrostatic And Surge Protection (TVS/ESD) · SMC

SMCJ11A from JUXING, 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 of the unidirectional SMCJ11A TVS diode (reverse stand-off voltage 11V, breakdown 12.2V min to 13.5V max at 1mA, max clamping 18.2V at 82.5A).
2 Anode passive Anode of the TVS diode (SMCJ11A is the unidirectional type, 1500W peak pulse power at 10/1000µs).

CAD (KiCad official)

  • Symbol: SMCJ11A
  • Footprint: Diode_SMD:D_SMC
  • 3D model: SMC (KiCad packages3D, STEP)
  • 3D model files: smcj11a-etched.step / smcj11a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smcj11a.step / smcj11a.glb are the bare package body.
