SD10U45L

LGE · Schottky Barrier Diodes (SBD) · TO-277

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).
