SMCJ40CA-TR

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

SMCJ40CA-TR from STMicroelectronics, in a SMC(DO-214AB). 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 A1 passive Bidirectional TVS terminal with no polarity; either terminal may connect to the protected line, with stand-off voltage VRM 40 V and breakdown 44.4 to 46.7 V in both directions.
2 A2 passive Second bidirectional TVS terminal with no polarity; 1500 W (10/1000 µs) peak pulse power, clamping 64.5 V at 24 A (10/1000 µs).

  • Symbol: SMCJ40CA-TR
  • Footprint: Diode_SMD:D_SMC
  • 3D model: SMC(DO-214AB) (KiCad packages3D, STEP)
  • 3D model files: smcj40ca-tr-etched.step / smcj40ca-tr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smcj40ca-tr.step / smcj40ca-tr.glb are the bare package body.
