MBR1045CT

MDD Microdiode Semiconductor · Schottky Diodes · TO-220AB-3

MBR1045CT from MDD Microdiode Semiconductor, in a TO-220AB-3. 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, which shares the common cathode at pin 2; the part is rated 45 V VRRM and 10.0 A total average forward current.
2 K passive Common cathode of both Schottky diodes, connected to the case (tab).
3 A2 passive Anode of the second Schottky diode, which shares the common cathode at pin 2.
