HER503G
Yangzhou Yangjie Elec Tech · Fast Recovery / High Efficiency Diodes · DO-27
HER503G from Yangzhou Yangjie Elec Tech, 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, the lead at the end marked by the color band; the datasheet states 'Color band denotes cathode end'. |
| 2 | A | passive | Anode, the lead at the end opposite the color band; the HER503G has a 200 V repetitive peak reverse voltage and 5.0 A average forward current. |
