SB1545L

MSKSEMI · Schottky Diodes · TO-277

SB1545L from MSKSEMI, 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 (PIN 1), one of two small anode pads tied together; the part is rated 45V reverse and 15.0A average forward current.
2 K passive Cathode terminal (PIN 2), the large cathode pad indicated by the cathode band; the part is rated 45V maximum DC blocking voltage with 0.47V forward drop at 15.0A.
3 A passive Anode terminal (PIN 3), the second small anode pad shown in the same symbol as PIN 1; the part is rated 45V reverse and 15.0A average forward current.
