Description

The RHRD440CC, RHRD460CC, RHRD440CCS and RHRD460CCS are hyperfast dual diodes with soft recovery characteristics (t_rr < 30ns). They have half the recovery time of ultrafast diodes and are silicon nitride passivated ionimplanted epitaxial planar construction.

These devices RHRD440 are intended for use as freewheeling/clamping diodes and rectifiers in a variety of switching power supplies and other power switching applications. Their low stored charge and hyperfast soft recovery minimize ringing
and electrical noise in many power switching circuits reducing power loss in the switching transistors.

Formerly developmental type TA49055.
