75A, 1200V Hyperfast Diode
The RHRG75120 is a hyperfast diode with soft recovery
characteristics (t
< 85ns). It has half the recovery time of
rr
ultrafast diodes and is 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 high frequency switching
power supplies and other power switching applications. Its
low stored charge and hyperfast soft recovery characteristic
minimize ringing and electrical noise in many power
switching circuits, thus reducing power loss in the switching
transistors.
Formerly developmental type TA49042.
