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

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.

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.

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.
