MUR120RLG

onsemi · Diodes - Fast Recovery Rectifiers · DO-41

MUR120RLG 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, identified by the polarity band on the axial body; this MUR120 device is rated for a peak repetitive reverse voltage (VRRM) of 200 V.
2 ANODE passive Anode, the lead opposite the polarity band; the average rectified forward current is 1.0 A at TA = 130°C for square-wave mounting method #3.
