SS1045SP

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

SS1045SP from YFW, 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 (pins 1 and 2 are tied together as the anode), part of a 45 V repetitive peak reverse, 10 A average forward Schottky rectifier.
2 A passive Anode terminal (shorted internally with pin 1 per the schematic), carrying up to 10 A average forward current at TL=100°C.
3 K passive Cathode terminal, the large tab/pad of the TO-277 package, with 45 V maximum DC blocking voltage for SS1045SP.
