Data Sheet April 1995 File Number 3945.1

75A, 400V - 600V Hyperfast Diodes

RHRU7540, RHRU7550 and RHRU7560 (TA49067) are
hyperfast diodes with soft recovery characteristics
(t

< 55ns). They have half the recovery time of ultrafast

RR

diodes and are silicon nitride passivated ion-implanted epi­taxial planar construction.

These devices 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.
