MBR40L120CT from NH, in a TO-220AB. 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 (Pin1), which shares the common cathode on Pin 2 and is rated at 120 V VRRM and 40 A total average forward current for the device. |
| 2 | K | passive | Common cathode of both Schottky diodes (Pin2), internally connected to the case/mounting tab, with 120 V VRRM. |
| 3 | A2 | passive | Anode of the second Schottky diode (Pin3), which shares the common cathode on Pin 2 and is rated at 120 V VRRM and 40 A total average forward current for the device. |
