KDR731S Datasheet, PDF (1/2 Pages) KEC(Korea Electronics) – SCHOTTKY BARRIER TYPE DIODE(SERIES CONNECTION)

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