MUR220RLG

onsemi · Diodes - Fast Recovery Rectifiers · DO-41

MUR220RLG from onsemi, in a DO-41. 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 CATHODE passive Cathode, marked by the polarity band on the package; the device is rated 200 V peak repetitive reverse voltage and 2.0 A average forward current at TA = 90°C.
2 ANODE passive Anode, the terminal opposite the polarity band (cathode).
