RURU50100
Data Sheet January 2000
50A, 1000V Ultrafast Diode
The RUR U50100 is an ultr afast diode with soft recovery
characteristics (t
< 125ns). It has low forward voltage drop
rr
and is of silicon nitride passivated ion-implanted epitaxial
planar construction.
This device is intended for use as a freewheeling/clamping
diode and rectifier in a variety of switching power supplies
and other powerswitchingapplications.Itslow stored charge
and ultrafast recovery with soft recovery characteristic
minimize ringing and electrical noise in many power
switching circuits, reducing power loss in the switching
transistors.
Formerly developmental type TA09910.
