Semtech Releases New QPL Schottky Diode for Military and Aerospace Markets

New diode is suitable for switching power supply and steering applications, functions in extreme environments

CAMARILLO, Calif., Oct. 31, 2018 – Semtech Corporation (Nasdaq: SMTC), a leading supplier of high-performance analog and mixed-signal semiconductors and advanced algorithms, 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 (Direct Current to Direct Current) 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 ISOPACTM modules for alternate topologies and higher current capabilities above the discrete device rating.”

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.
