V20PW45-M3 from Vishay Intertech, in a TO-252-2. 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 | Pin 1 is labelled K (cathode) in the pin diagram; the datasheet gives a maximum repetitive peak reverse voltage of 45 V and an average forward rectified current of 20 A for the device. |
| 2 | HEATSINK | passive | Pin 2 is the heatsink tab, labelled HEATSINK in the pin diagram; the datasheet does not state its electrical connection beyond this label and gives a junction-to-mount thermal resistance RθJM of 1.8 °C/W. |
| 3 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
