1.5KE250A from DOWO, 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 lead, marked by the color band on the DO-201 body; the 1.5KE250A is unidirectional with VBR 237.5 to 262.5 V at 1 mA and VRWM 214 V. |
| 2 | A | passive | Anode lead, at the end opposite the color band; the 1.5KE250A has a maximum clamping voltage of 344 V at IPP 4.36 A and a 1500 W 10/1000 µs peak pulse power rating. |
