SMCJ33CAHE3_A

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

SMCJ33CAHE3_A from Vishay Intertech, 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 Bi-directional TVS terminal (no cathode band or marking on bi-directional types), electrical characteristics apply in both directions, VWM 33 V for SMCJ33CA.
2 A2 passive Second bi-directional TVS terminal, interchangeable with the other terminal, with no polarity marking on bi-directional types.
