Semtech’s New 1N5822 QPL Schottky Diode Now Qualified to Space Grade

New JANS qualification opens this device up for sale into satellite/spacecraft applications

CAMARILLO, Calif., Nov. 18, 2020 – Semtech Corporation (Nasdaq: SMTC), a leading supplier of high-performance analog and mixed-signal semiconductors and advanced algorithms, announced the qualification of its new Schottky diode to space grade.

The new addition, JANS1N5822 (also available as JANS1N5822US in MELF surface mount packaging), is Semtech’s first Schottky diode for use in space applications. This diode will add to the range of QPL high reliability devices available from Semtech. This qualification will make Semtech the second qualified manufacturer for this highly specialized diode.

“Semtech’s new space grade qualification provides another source for this popular device to our satellite and spacecraft customer base,” said Alan Burchfield, Power and High Reliability Product Line Director for Semtech’s Wireless and Sensing Products Group. “As with the rest of the product family, this device and the die within can be used as building blocks for custom devices to match our customer’s specific needs.”
