FEATURES
A
Low Forward Voltage : V
F
max=0.55V
Fast reverse recovery time (trr max=10nS)
Low switching noise.
Low leakage current and high reliablility due to
Highly reliable planar structure.
Series connection of 2 elements in an ultrasmall-
sized Package facilitates high-density mounting and
permits KDR731 applied equipment to be made smaller.
