RHRP30120
Data Sheet January 2000 File Number 3409.3
30A, 1200V Hyperfast Diode
The RHRP30120 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 free wheeling/clamping
diode and rectifier in a variety of high frequency switching
power supplies and other power s witching applications . Its low
stored charge and hyperfastsoftrecovery minimize ringing and
electrical noise in many power switching circuits, reducing
power loss in the switching transistors .
Formerly developmental type TA49041.
