1.5SMC75A

MSKSEMI · ESD And Surge Protection (TVS/ESD) · SMC

1.5SMC75A from MSKSEMI, in a SMC. 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 K passive Cathode of the unidirectional TVS, marked by the color band, with 64.10V reverse stand-off (VRWM), 71.30~78.80V breakdown at 1mA and 103.0V maximum clamping at 14.8A IPP.
2 A passive Anode of the unidirectional TVS, opposite the color-band end, and the return side for the 1500W (10/1000μs) peak pulse rating.
