3-A / 40-V QPL Schottky Diode for Military and Aerospace Markets

November 01, 2018 by Paul Shepard

Semtech Corporation announced the addition of a new Qualified Products List (QPL) Schottky diode to its High-Reliability Product family targeting military and aerospace applications. The new addition, 1N5822, is Semtech’s first Schottky diode, adding to the wide range of QPL diodes, Transient Voltage Suppressors and Zeners already available.

Semtech has now become only the second qualified manufacturer for this highly specialized diode.

“Semtech’s new Schottky diode expands our QPL offerings, enabling higher efficiency at lower output voltages for dc-dc converters and steering applications,” said Alan Burchfield, Power and High-Reliability Product Line Director for Semtech’s Wireless and Sensing Products Group.

“This diode also becomes an available building block for Semtech’s epoxy-encapsulated modules and ISOPAC™ modules for alternate topologies and higher current capabilities above the discrete device rating,” Burchfield added.

The Schottky diode, 1N5822, is qualified to MIL-PRF-19500/620 up to JANTXV level and is available in axial and surface mount (MELF) packages. The device is available through distribution. For pricing and purchasing options please inquire by contacting a local sales office.
