2003. 2. 25 1/2
SEMICONDUCTOR
TECHNICAL DATA
KDR732E
SCHOTTKY BARRIER TYPE DIODE
(TWIN TYPE, CATHODE COMMON)
Revision No : 1
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.
Ultrasmall-sized package permtting KDR732
applied sets to be made small and slim.
