MBR40100CT-B

YFW · Schottky Barrier Diodes (SBD) · TO-220AB

MBR40100CT-B from YFW, 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 leg (PIN 1), rated 100 V VRRM and 20 A average forward current per leg.
2 K passive Common cathode of both Schottky legs (PIN 2), which is also connected to the tab, and carries up to 40 A total average forward current.
3 A2 passive Anode of the second Schottky diode leg (PIN 3), rated 100 V VRRM and 20 A average forward current per leg.
