Description
Littelfuse DST series Ultra Low V_F Schottky Barrier
Rectifier is designed to meet the general requirements
of commercial and industry applications by providing high
temperature, low leakage and lower V_F products.
It is suitable for high frequency switching mode power
supply, free-wheeling diodes and polarity protection
diodes.
Features
• Ultra low forward voltage
drop
• High frequency operation
• High junction
temperature capability
• Guard ring for enhanced
ruggedness and long
term reliability
• Common cathode
