DLA Certification for Hi-Rel Diodes and Transistors: How It Works and Why It’s Important

Jan. 17, 2017

Capping Booth w Video Screen_small.jpgIf you’re designing electronic systems for aerospace and defense applications, identifying government certified, hi-rel diodes and transistors is as easy as looking through the Defense Logistics Agency’s (DLA) Qualified Manufacturers List (QML) and Qualified Product List (QPL) slash sheets. If you’re the supplier that offers DLA certified diodes and transistors to these designers, things aren’t nearly so easy.

The process via which these components are screened and certified by the DLA is exacting and exhaustive, and rightfully so. Whether they’re specified to JANTXV, JANTX or JANS qualification grades, these components are expected to provide highly reliable performance under extremely demanding conditions, for long lifespans, with very low failure rates.

In the case of JANS components – short for Joint Army-Navy Space, the highest level of qualification – the rigors that these components will be subjected to are intense. Among the many severe conditions that a spacecraft will encounter: extreme vibration during launch, drastic temperature fluctuations as it orbits in and out of sunlight and floating debris that can cause electronic system interference. Considering that an entire mission’s success can hinge on the integrity and reliability of a single component, it’s no wonder that the DLA takes such great pains to screen and qualify each component.

The certification process entails a team of DLA experts assessing a supplier’s quality standards spanning from the fab to the assembly, test and manufacturing facilities. The quality and heritage of each individual semiconductor component must be traceable all the way down to the die level. Upon successful completion of the audit, DLA certifications for semiconductor components typically extend for two years, at which time a new audit is initiated and the process starts all over again.

The effort and investment required for a semiconductor company to support this stringent DLA certification activity is simply too much for many suppliers to bear – but not MACOM. In fact, we increased our investment in this domain when we acquired Aeroflex/Metelics in 2015. We enthusiastically embrace this DLA certification activity as a necessary requirement that enables us to increase the value that we provide for our aerospace and defense customers in the United States and around the world.

Leveraging our DLA certified wafer fab and manufacturing facilities in Lowell and Lawrence, Massachusetts, respectively, we continue to grow our portfolio of hi-rel, JAN certified diodes and transistors in conformance with the MIL-PRF-19500P standard, with select support for MIL-PRF-38534, MIL-PRF-38535, utilizing test methods defined in the MIL-STD-883 and MIL-STD-750 standards.

The strength of MACOM’s customer relationships in the aerospace and defense market – developed over six decades – is directly attributable to the quality of the products, service and application expertise that we provide, bolstered by strategic distributor engagements that expand our global reach. Our DLA certifications are key to this effort.

In the months and years ahead, designers will review their slash sheets and see increasing numbers of hi-rel MACOM diodes and transistors to choose from. Each and every new component reflects our unrelenting commitment to the aerospace and defense market, and the uncompromising quality standards that MACOM and the DLA demand.
