6A, 400V - 600V Hyperfast Diodes
Features
• Hyperfast with Soft Recovery<30ns
RHRD640, RHRD650, RHRD660, RHRD640S, RHRD650S
and RHRD660S are hyperfast diodes with soft recovery charac-

ultrafast diodes and are sil icon 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 switch-
ing transistors.
Applications
• Switching Power Supplies
• Power Switching Circuits
• General Purpose
