RHRG50100
50A, 1000V Hyperfast Diode
The RHRG50100 is a hyperfast diode with soft recovery
characteristics (t
rr
< 75ns). It has half the recovery time of
ultrafast diodes 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 power switching applications. Its low stored charge
and hyperfast soft recovery minimize ringing and electrical
noise in many power switching circuits, thus reducing power
loss in the switching transistors.
Formerly developmental type TA49066.
