Littelfuse DST series Ultra Low V

Rectifier is designed to meet the general requirements

of commercial and industry applications by providing high

temperature, low leakage and lower V

It is suitable for high frequency switching mode power

supply, free-wheeling diodes and polarity protection

diodes.

• Ultra low forward voltage

drop

• High frequency operation

• High junction

temperature capability

• Guard ring for enhanced

ruggedness and long

term reliability

• Common cathode

configuration in ITO-

220AB package

• Switching mode power

supply

• DC/DC converters

• Free-Wheeling diodes

• Polarity Protection Diodes
