Description

Littelfuse DST series Ultra Low V_FSchottky Barrier

Rectiﬁer is designed to meet the general requirements

of commercial and industry applications by providing high

temperature, low leakage and lower V_Fproducts.

It is suitable for high frequency switching mode power

supply, free-wheeling diodes and polarity protection

diodes.

Features

• Ultra low forward voltage

• Single die inTO-277B
