Schottky Barrier Rectifier
DST2045C, 2x10A, 45V, TO-220AB, Common Cathode
DST2045C
Description
RoHS
Pb
Littelfuse DST series Ultra Low V
F
Schottky Barrier
Rectifier is designed to meet the general requirements
of commercial and industry applications by providing high
temperature, low leakage and lower V
F
products.
It is suitable for high frequency switching mode power
supply, free-wheeling diodes and polarity protection
diodes.
