SMCJ9.0CA-AT

Brightking Elec (TAIWAN) · TVS · SMC(DO-214AB)

SMCJ9.0CA-AT from Brightking Elec (TAIWAN), 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 Terminal 1 passive Bidirectional TVS terminal (no polarity for the CA type) with VRWM 9.0V, VBR 10.00~11.10V at 1mA, and max clamping voltage 15.4V at IPP 97.4A.
2 Terminal 2 passive Second bidirectional TVS terminal, interchangeable with terminal 1, with reverse leakage max 10μA at VRWM 9.0V and 1500W peak pulse power at 10/1000μs.

CAD (KiCad official)

  • Symbol: SMCJ9.0CA-AT
  • Footprint: Diode_SMD:D_SMC
  • 3D model: SMC(DO-214AB) (KiCad packages3D, STEP)
  • 3D model files: smcj9-0ca-at-etched.step / smcj9-0ca-at-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smcj9-0ca-at.step / smcj9-0ca-at.glb are the bare package body.
