20V80SP from YFW, in a TO-277. 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 | A1 | passive | Anode terminal of the first leg of the dual Schottky rectifier, rated 80 V reverse voltage and 20 A average forward current per diode. |
| 2 | A2 | passive | Anode terminal of the second leg of the dual Schottky rectifier, rated 80 V reverse voltage and 20 A average forward current per diode. |
| 3 | K | passive | Common cathode terminal (exposed tab) shared by both diode legs, with thermal resistance junction to case of 72 °C/W typical. |
