DST1045S-A

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 applications, such as free-wheeling and polarity

protection diodes.
