IR Expands Offering of QPL-Certified Schottky Rectifiers for Space Applications

Tue, 02/08/2011 - 11:11am

International Rectifier 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 45 V and 100 V reverse recovery voltage, rated from 15 A to 45 A 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.

QPL_Schottky-Space AppsSchottky 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.
