SP1560L from Changjing, 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 | Anode 1 | passive | Anode terminal 1 of the Schottky rectifier, tied internally to Anode 2; 60V VRRM and 15A average forward current for the device. |
| 2 | Anode 2 | passive | Anode terminal 2 of the Schottky rectifier, tied internally to Anode 1; 60V VRRM and 15A average forward current for the device. |
| 3 | Cathode & Heatsink | passive | Cathode terminal, which is also the exposed heatsink tab; RθJ-L is 25 °C/W junction to terminal. |
