File Number 3408.2
75A, 1200V Hyperfast Diode
The RHRU75120 (TA49042) is a hyperfast diode with soft
recovery characteristics (t
RR
< 85ns). It has half the recov-
ery time of ultrafast diodes and is silicon nitride passivated
ion-implanted epitaxial planar construction.
This device is intended for use as a freewheeling/clamping
diode and recti鏗乪r in a variety of high frequency switching
power supplies and other power switching applications. Its
low stored charge and hyperfast soft recovery minimize ring-
ing and electrical noise in many power switching circuits
reducing power loss in the switching transistors.
