component
SA85CA
Public Made by Adomby adom
Brightking Elec (TAIWAN) TVS, DO-15. Unpolarised two-terminal part: the datasheet prints no pin numbers, so pins 1 and 2 follow the library convention, KiCad symbol/footprint/3D.

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. |
