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 -55C to +125C environments but with reduced peak current capability: while the UC3611 in plastic has higher current rating over a 0C to +70C ambient temperature range.
