Description
Littelfuse DST series Ultra Low VF Schottky Barrier
Rectifier is designed to meet the general requirements
of commercial and industry applications by providing high
temperature, low leakage and lower VF 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
