SD12U120SL
LGE · Schottky Barrier Diodes (SBD) · TO-277
SD12U120SL 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 the two small pads tied together on the left of the pin configuration drawing; the diode is rated 12A average forward current. |
| 2 | A | passive | Anode terminal, the second small pad tied internally to the other anode pad in the pin configuration drawing; the diode is rated 12A average forward current. |
| 3 | K | passive | Cathode terminal, the large pad on the bar side of the diode symbol; the part has a 120V peak repetitive reverse voltage rating. |
