RHRP30120
30A, 1200V Hyperfast Diode
The RHRP30120 is a hyperfast diode with soft recovery
characteristics (trr < 65ns).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 high frequency switching
power supplies and other power switching applications. Its low
stored charge and hyperfast soft recoveryminimize ringing and
electrical noise in many power switching circuits, reducing
power loss in the switching transistors.
Formerly developmental type TA49041.
