SB1045L from GOODWORK, 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 lead (small pad, one of two anode leads) of the Schottky rectifier, rated 10.0 A average forward current and 45 V DC blocking voltage. |
| 2 | K | passive | Cathode, the large tab/pad on the opposite side from the leads and marked by the cathode band, which carries the 10.0 A average forward current with 0.53 V maximum forward voltage at 10.0 A. |
| 3 | A | passive | Anode lead (small pad, second of two anode leads) of the Schottky rectifier, rated 10.0 A average forward current and 45 V DC blocking voltage. |
