MBR3045DC-R

YFW · Schottky Barrier Diodes (SBD) · TO-263

MBR3045DC-R from YFW, in a TO-263. 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 A1 passive Anode of the first Schottky diode leg, rated 15 A average forward current per leg and 45 V repetitive peak reverse voltage.
2 K passive Common cathode of both Schottky legs (centre pin, connected to the case tab), with 30 A total average forward current.
3 A2 passive Anode of the second Schottky diode leg, rated 15 A average forward current per leg and 45 V repetitive peak reverse voltage.
