MBR2045A from MOT, 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 | Anode | passive | Anode of the first diode leg; the datasheet gives the per-leg limits of VRRM 45 V and IO 10 A per leg, with a non-repetitive surge of 200 A (8.3 ms half sine). |
| 2 | Common Cathode | passive | Common cathode shared by both diode legs; the datasheet gives the total average rectified output current IO of 20 A and operating/storage range of -55 to +175 °C. |
| 3 | Anode | passive | Anode of the second diode leg; the datasheet gives the per-leg limits of VRRM 45 V and IO 10 A per leg, with a non-repetitive surge of 200 A (8.3 ms half sine). |
