SMCJ90A-L

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

SMCJ90A-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 of the unidirectional TVS diode (for bipolar CA types the two terminals are interchangeable); the SMCJ90A-L has 90 V reverse stand-off voltage.
2 Anode passive Anode of the TVS diode; the SMCJ90A-L has 90 V stand-off, 100 V min breakdown voltage and 146 V max clamping voltage at 4.1 A peak pulse current.

CAD (KiCad official)

  • Symbol: SMCJ90A-L
  • Footprint: Diode_SMD:D_SMC
  • 3D model: SMC (KiCad packages3D, STEP)
  • 3D model files: smcj90a-l-etched.step / smcj90a-l-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smcj90a-l.step / smcj90a-l.glb are the bare package body.
