RHRG30120
Data Sheet January 2000
30A, 1200V Hyperfast Diode
The RHRG30120 is a hyperfast diode with soft recovery
characteristics (t
< 65ns). It has half the recovery time of
rr
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 high frequency switching
power supplies and other power switching applications. Its
low stored charge and hyperfast soft recovery minimize
ringing and electrical noise in manypower switching circuits,
thus reducing power loss in the switching transistors.
Formerly developmental type TA49041.
