Description
The RHRG75120 (TA49042) is a hyperfast diode with soft
recovery characteristics (tRR < 85ns). It has half the recovery
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 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 switch-
ing circuits reducing power loss in the switching transistors.
