HER308-B from GOODWORK, in a DO-27. 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 end of the axial rectifier, marked by the color band; the datasheet states 'Polarity: Color band denotes cathode end'. |
| 2 | A | passive | Anode lead of the axial rectifier (opposite end from the color band); HER308 is rated 1000 V DC blocking voltage and 3.0 A average forward current. |
