MBRB2045CT

baocheng Shandong Baocheng Elec · Schottky Diodes · TO-263

MBRB2045CT from baocheng Shandong Baocheng Elec, 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; the diagram shows PIN1 as the anode of one diode whose cathode joins the common PIN2 (45 V for MBRB2045CT, 10 A per diode VFM 0.68 V at IFM=10.0 A).
2 K (common cathode) passive Common cathode of both Schottky diodes, shown as PIN2 in the diagram; total rectified output current is 20 A (IO).
3 A2 passive Anode of the second Schottky diode; the diagram shows PIN3 as the anode of one diode whose cathode joins the common PIN2.
