TPSMB75CA

Littelfuse · ESD And Surge Protection (TVS/ESD) · DO-214AA

TPSMB75CA from Littelfuse, in a DO-214AA. 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 with no polarity; either terminal may connect to the protected line (VR 64.1V, VBR 71.3-78.8V at 1mA, VC 103V at 5.9A Ipp).
2 A2 passive Second bidirectional TVS terminal with no polarity and no cathode band; interchangeable with the other terminal (600W peak pulse power at 10/1000µs).
