MUR3040CT

YFW · Fast Recovery / High Efficiency Diodes · TO-220AB

MUR3040CT 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 diode leg (PIN 1), rated 15 A average forward current per leg and 400 V repetitive peak reverse voltage.
2 CATHODE passive Common cathode of both diode legs (PIN 2, also the tab), with 30 A total average forward current and 400 V maximum DC blocking voltage.
3 A2 passive Anode of the second diode leg (PIN 3), rated 15 A average forward current per leg and 400 V repetitive peak reverse voltage.
