MBR1645DT

OSEN · Schottky Diodes · TO-220

MBR1645DT from OSEN, in a TO-220. 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 of the dual common-cathode rectifier (45 V VRRM, 16 A total device average forward current).
2 K passive Common cathode of both Schottky diodes, also connected to the TO-220 tab/case (Rth(j-c) 1.5 °C/W max).
3 A2 passive Anode of the second Schottky diode of the dual common-cathode rectifier (45 V VRRM, 16 A total device average forward current).
