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.

Evaluation board

ESDEVM — Universal evaluation module for ESD diode packages, including 0402, 0201, and others

The electrostatic-sensitive device (ESD) evaluation module (EVM) is a development platform for most of our ESD portfolio. The board comes with all traditional ESD footprints in order to test any number of devices. Devices can be soldered onto their respect footprint and then tested. For typical (...)
