MUR4100ERLG

onsemi · Diodes - Fast Recovery Rectifiers · DO-201AD

MUR4100ERLG from onsemi, in a DO-201AD. 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 K passive Cathode, indicated by the polarity band; the MUR4100E blocks reverse voltage up to 1000 V (VRRM/VRWM/VR).
2 A passive Anode; the MUR4100E carries 4.0 A average rectified forward current at TA = 35°C.
