Military Equivalent Bare Die Up-Screening

Building high-reliability semiconductor solutions from the ground up

For mission-critical applications in military, aerospace, and space environments, standard commercial-off-the-shelf (COTS) components often aren't enough.

Our Military-Equivalent Bare Die Up-Screening capabilities ensure that every component meets the stringent demands of high-reliability systems, providing a robust foundation for your most sensitive designs. We specialize in transforming COTS bare die into high-reliability devices, ready for the harshest conditions.

To ensure rapid product development and product availability, Central Semiconductor maintains an extensive wafer inventory and test capacity in its Long Island, New York facility.

For customers requiring high reliability MIL-equivalent semiconductor devices, COTS bare die products are up-screened to MIL-PRF-38534 Class H and K equivalents and to MIL-PRF-19500 Class HC and KC equivalents.

Central Semiconductor offers extensive testing and screening services. Our up-screened products include a wide range of devices critical to high-reliability systems:  

Devices eligible for up-screening include:

• Small signal transistors
• Bipolar power transistors
• MOSFETs and JFETs
• EOS protection devices (TVS)
• Diodes/Rectifiers
• Thyristors
