SA85CA

Brightking Elec (TAIWAN) · TVS · DO-15

SA85CA from Brightking Elec (TAIWAN), in a DO-15. 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 Terminal 1 passive Axial lead of the bidirectional SA85CA (VRWM 85 V, VBR 94.40~104.00 V at 1 mA, VC 137 V at 3.7 A); no polarity, no cathode band.
2 Terminal 2 passive Second axial lead of the bidirectional SA85CA, interchangeable with the other lead since the part is bidirectional with no polarity marking.
