MBR40L120CT

NH · Schottky Diodes · TO-220AB

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.
