SMCJ22CA-AT

Brightking · TVS · SMC(DO-214AB)

SMCJ22CA-AT from Brightking, 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 1 (SMCJ22CA-AT, no polarity, no cathode band) with VRWM 22.0 V, VBR 24.40~26.90 V at 1 mA, and VC 35.5 V at IPP 42.3 A.
2 A2 passive Bidirectional TVS terminal 2 (SMCJ22CA-AT, interchangeable with terminal 1) rated for 1500 W peak pulse power at 10/1000 μs.
