STTH50W03CW from STMicroelectronics, in a TO-247-3. 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 of diode 1, rated 25 A average forward current per diode with 300 V repetitive peak reverse voltage. |
| 2 | K | passive | Common cathode of both diodes, which is also connected to the tab, and is rated 300 V VRRM. |
| 3 | A2 | passive | Anode of diode 2, rated 25 A average forward current per diode with 300 V repetitive peak reverse voltage. |
