Welcome! SST Components, Inc is now doing business as VPT Components!

We’re One of the Largest Providers of JAN Certified Semiconductors and Provide Full-Service Independent Unbiased Testing and Custom Assembly of Electronic Components

VPT Components was formed as a collaboration between VPT Inc., a global leader in power conversion solutions, and SST Components, Inc., a MIL-PRF-19500 JANS certified semiconductor manufacturer. VPT Components is now one of the largest providers of JAN certified semiconductors along with a full-service facility for the independent, unbiased testing and custom assembly of electronic components.

VPT Components acquired the assets of MACOM’s Hi-Rel Components business (formerly Aeroflex Metelics) located in Lawrence, MA in Sepember 2018 and we are committed to supporting the former MACOM slash sheet qualifications as previously listed on the QML. This acquisition provides us with an additional 40,000 square feet of state of the art manufacturing and test capability of high reliability discrete semiconductors as we grow our product portfolio.

We are also maintaining our Billerica, MA operations with 10,000 total square feet and 4,500 square feet of class 10,000 cleanroom for discrete/hybrid assembly. Our Billerica operation includes the addition of $5M in new test, assembly, and screening equipment that enables us to assemble a wide variety of hermetically sealed components to the highest quality levels. VPT Components keeps pace with advancing technology by continually adding new and increasingly sophisticated automatic test and assembly capabilities.

Our expanding product portfolio includes MIL-PRF-19500 qualified Rad Hard NPN and PNP small signal and power switching transistors, SCRs, and MOSFETs along with an extensive offering of Zeners, rectifiers, switching diodes and Schottky products including JANHC and JANKC qualified die. Custom products and packaging services are also available.
