Description

The RHRG75120 is a hyperfast diode with soft recovery characteristics (t_rr< 85ns). It has half the recovery time of ultrafast diodes and is silicon nitride passivated ion-implanted epitaxial planar construction.

This device RHRG75120 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 switching circuits, thus reducing power loss in the switching transistors.

Formerly developmental type TA49042.
