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. |
