SEMICONDUCTOR
TECHNICAL DATA
HIGH SPEED RECTIFICATION
(SWITCHING REGULATORS, CONVERTERS, CHOPPERS)
UNIVERSAL-USE RECTIFIERS.
FEATURES
·Low Forward Voltage : VF 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 SOT-23 package
facilitates high-density mounting and permits KDR731S
applied equipment to be made smaller.
