LGE · Schottky Barrier Diodes (SBD) · TO-277
SD10U50SL 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 terminal, one of two left-side leads tied together internally in the pin configuration diagram; the diode is rated 10A average forward current and 50V repetitive peak reverse voltage. |
| 2 | A | passive | Anode terminal, the second left-side lead tied internally to the first anode lead in the pin configuration diagram; the combined anode carries up to 10A average forward current. |
| 3 | K | passive | Cathode terminal, the single right-side pad at the diode bar in the pin configuration diagram, with 50V repetitive peak reverse voltage rating. |
