DSTB2045C

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 low V_Fproducts.

It is suitable for high frequency switching mode power

supply applications, as free-wheeling and polarity

protection diodes.

Features

• Ultra low forward voltage
