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-leaded 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.
