1.5KE350A from Brightking, in a DO-201. 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 unidirectional 1.5KE350A; stand-off voltage VRWM 300V, breakdown 332~368V at 1mA, max clamping 482V at 3.2A. |
| 2 | A | passive | Anode axial lead at the end opposite the cathode band; the part is unidirectional (the 'A' suffix is a 5% VBR tolerance, 'CA' is the bidirectional version). |
