SD20U150SL 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: one of the two small leads, tied internally to the other anode lead, on the diode symbol side of the 20A/150V Schottky rectifier. |
| 2 | A | passive | Anode: second small lead, tied internally to the other anode lead, on the diode symbol side of the 20A/150V Schottky rectifier. |
| 3 | K | passive | Cathode: the large single tab/pad on the bar side of the diode symbol; footprint shows a 4.40 x 3.50 mm pad. |
