MUR420RLG

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

MUR420RLG 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, marked by the polarity band; the diode conducts when the anode is positive relative to this terminal, and reverse voltage rating is 200 V for MUR420.
2 A passive Anode terminal of the axial-lead ultrafast rectifier, rated for 4.0 A average forward current (MUR420).
