SAC45 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 | K | passive | Cathode, marked by the color band on the axial DO-15 body (unidirectional device); reverse stand-off voltage VRWM 45.0V, minimum breakdown 50.00V at 1mA for SAC45. |
| 2 | A | passive | Anode, axial lead opposite the cathode band; SAC45 maximum clamping voltage is 77.0V at IPP 6.8A with 500W peak pulse power at 10/1000μs. |
