SD10U45L from LGE, 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 | A | passive | Anode (left pin), connected internally to the right pin; the device is rated 10A average forward current and 45V repetitive peak reverse voltage. |
| 2 | A | passive | Anode (right pin), connected internally to the left pin; the device is rated 10A average forward current and 45V repetitive peak reverse voltage. |
| 3 | K | passive | Cathode, the bottomside heat sink of the TO-277 package, which is the cathode pad used for thermal dissipation (Rth(JA) 31 °C/W on the specified PCB). |
