1.5SMC51CA-E3

Vishay Intertech · TVS · SMC(DO-214AB)

1.5SMC51CA-E3 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 Bidirectional (CA suffix) TVS terminal with electrical characteristics applying in both directions and no polarity marking, interchangeable with the other terminal (VWM 43.6 V, VBR 48.5 V to 53.6 V for the 51CA).
2 A2 passive Bidirectional (CA suffix) TVS terminal with electrical characteristics applying in both directions and no polarity marking, interchangeable with the other terminal (VC max 70.1 V at IPPM 21.4 A for the 51CA).
