International Rectifier, IR, a world leader in power management technology, today announced the expansion of the company's offering of high reliability Schottky rectifiers in accordance with the Defense Logistics Agency (DLA) Land and Maritime Qualified Products List (QPL) for space applications including satellite bus power systems and payload power supplies. The QPL-certified devices are available in 45V and 100V reverse recovery voltage, rated from 15A to 45A current, and offered in a TO-254, TO-257, TO-258 or SMD0.5 hermetic package in a choice of single device, doubler or common cathode configurations. Schottky rectifiers are used primarily in the output stage of a switching power supply. Delivering very low forward voltage drops (Vf) and fast turn-off characteristics (trr), these new devices minimize conduction and switching losses in power supply designs. "The new family of devices extends IR's offering of QPL-qualified Schottky rectifiers, providing greater design flexibility for power system designers of satellite power distribution and payload power supplies. With a certified qualification and manufacturing process, the new devices eliminate the need for Source Control Drawings (SCDs) and their associated cost and time-to-market," said Odile Ronat, discrete marketing manager, HiRel Business Unit. The Qualified Parts List (QPL) is the U.S. Department of Defense's list of qualified semiconductor products produced by qualified suppliers in accordance with MIL-PRF-19500 screening requirements. Suppliers are audited periodically, thus assuring that all customers receive products that meet government standards. Datasheets are available on the International Rectifier website. Availability and Pricing Pricing ranges from US $263 for the JANS1N6660DT1 to US $350 for the JANS1N7070CCT3 each in100-unit quantities. Production orders are available immediately. Prices are subject to change. These products are subject to U.S. export control laws and regulations. www.irf.com
