EL SEGUNDO, Calif., 25 March 2007. International Rectifier in El Segundo, Calif., is introducing high-reliability Schottky rectifiers in accordance to the Defense Supply Center Columbus (DSCC) Qualified Products List (QPL).

These QPL devices (see related story) target high-reliability applications in switching power supplies (SMPS), satellite power distribution systems, resonant power converters, and low-voltage motor control.

QPL certification ensures repeatable performance regardless of device lot or maturity and eliminates the need for customers to generate their own Source Control Drawings (SCDs), reducing cost and time to market.

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), the devices minimize conduction and switching losses in power supply designs.

International Rectifier's new QPL Schottky rectifiers feature a 45 to 100 volts reverse-voltage range, a 0.69 to 1.3 volts forward-voltage range, and 10 to 35 amps current rating. Available in surface-mount and through-hole packages, the devices are screened to JANTX, JANTXV, and JANS levels per MIL-PRF-19500/MIL-STD-750, offering customers the highest reliability available.

The Qualified Parts List 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.
