SMCJ14A

YFW · ESD And Surge Protection (TVS/ESD) · DO-214AB(SMC)

SMCJ14A from YFW, in a DO-214AB(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 SMCJ14A; the datasheet gives a 14 V stand-off (VRWM), a 15.6 V to 17.2 V breakdown range at 1 mA test current, and a 23.2 V maximum clamp voltage at 64.7 A peak pulse current.
2 Anode passive Anode of the unidirectional SMCJ14A; the datasheet limits the maximum instantaneous forward voltage to 3.5 V at 100 A for unidirectional devices and rates the part for 1500 W peak pulse power on a 10/1000 µs waveform.

  • Symbol: SMCJ14A
  • Footprint: Diode_SMD:D_SMC
  • 3D model: DO-214AB(SMC) (KiCad packages3D, STEP)
  • 3D model files: smcj14a-etched.step / smcj14a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smcj14a.step / smcj14a.glb are the bare package body.
