SA45A from Brightking, 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, the axial lead on the color-band side of the unidirectional SA45A (VRWM 45.0 V, VBR 50.00~55.30 V at 1 mA, VC 72.7 V at 7.0 A IPP). |
| 2 | A | passive | Anode, the axial lead opposite the cathode band; it is the lead that goes negative relative to the cathode in normal use, with the diode clamping in reverse breakdown (IR 1 µA max at VRWM 45.0 V). |
