MBR3045DT

OSEN · Schottky Diodes · TO-220AB

MBR3045DT from OSEN, in a TO-220AB. 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 (common-cathode dual); each leg is rated 45 V VRRM, with total device average forward current of 30 A.
2 K passive Common cathode of both Schottky diodes, tied to the center lead; VRRM is 45 V and total device IF(AV) is 30 A.
3 A2 passive Anode of the second Schottky diode (common-cathode dual); each leg is rated 45 V VRRM, with total device average forward current of 30 A.
