MBR20150CT 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 (pin 1 in the internal diagram), with the common cathode on pin 2; part is rated 150 V VRRM and 20.0 A total average forward current. |
| 2 | K/CASE | passive | Common cathode of both Schottky diodes, connected to the case/mounting tab in the internal diagram; rated 150 V maximum DC blocking voltage. |
| 3 | A2 | passive | Anode of the second Schottky diode (pin 3 in the internal diagram), with the common cathode on pin 2; part is rated 150 V VRRM and 20.0 A total average forward current. |
