DESCRIPTION

This four-diode array is designed for general

purpose use as individual diodes or as a

high-speed, high-current bridge. It is particularly

useful on the outputs of high-speed power

MOSFET drivers where Schottky diodes are

needed to clamp any negative excursions caused

by ringing on the driven line.These diodes are also

ideally suited for use as voltage clamps when

driving inductive loads such as relays and

solenoids, and to provide a path for current

free-wheeling in motor drive applications.The use

of Schottky diode technology features high

efficiency through lowered forward voltage drop

and decreased reverse recovery time.This single

monolithic chip is fabricated in both hermetic

CERDIP and copper-eaded plastic packages.

The UC1611 in ceramic is designed for –55°C to

125°C environments but with reduced peak

current capability: while the UC3611 in plastic has

higher current rating over a 0°C to 70°C ambient

temperature range.
