SP5300L

Changjing · Schottky Diodes · TO-277

SP5300L 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 1 of the Schottky rectifier (300V VRRM, 5A IF(AV)), internally common with Anode 2.
2 Anode 2 passive Anode 2 of the Schottky rectifier (300V VRRM, 5A IF(AV)), internally common with Anode 1.
3 Cathode passive Cathode, connected to the exposed heatsink tab of the TO-277 package.
