Hi-Rel Analog

Renesas' radiation hardened (rad hard) and radiation tolerant (rad tolerant) analog ICs are meticulously designed to meet the rigorous demands of mission-critical applications, including space, aerospace, and defense systems. Our product offerings have optimized performance, consider system SWaP-c (size, weight, power, and cost) concerns, and speed time to market. With radiation-hardened components, low power consumption, and robust designs, our analog solutions are trusted for their reliability and precision in the most challenging conditions.

Manufacturing & Test Information

Renesas has an unparalleled track record of providing highly reliable, efficient, and accurate space-grade products that fit a wide range of space applications, including satellite communications and space flight systems.

The Total Ionizing Dose (TID) response of semiconductors is a key issue in space applications. Renesas addresses this by performing Radiation Lot Acceptance Testing (RLAT) on all space-grade products. For radiation hardened products, low dose rate and/or high dose rate RLAT is performed on a wafer-by-wafer basis (see part specification for more information). For radiation tolerant products, low dose rate RLAT is performed on a per wafer lot basis. Renesas also designs its space products to handle heavy ion interactions with minimal disruptions to functional operation while mitigating all Single Event Effects (SEE) including Single Event Transients (SET), Upsets (SEU), and destructive events like Burnout and Latch-up (SEB/L).

Renesas' radiation-hardened hermetic and plastic products follow MIL-PRF-38535/QML qualified production flows and are 100% burned-in to ensure the highest reliability. Renesas’ radiation-tolerant space plastic products follow an automotive-like production flow to provide robust, cost-sensitive options to support New Space applications.

By leveraging the latest technology, the Intersil space products group is releasing QML Class V, QML Class P, QML Class Q, and radiation tolerant space plastic products that are revolutionizing the Hi-Reliability and space marketplaces.

Over the past 19 years, the space industry has placed a higher value on understanding the effects that long-term, low dose radiation can have on ICs. Intersil's radiation testing specialist Nick van Vonno discusses why this shift has occurred and what we are doing to address this change.

Learn about Renesas's family of radiation-tolerant plastic-package ICs designed to support the emerging field of small satellites that will provide solutions such as high-speed Internet connections to hundreds of millions of users in communities, governments, and businesses worldwide. These ICs deliver rad-tolerance performance at a much lower cost point versus radiation assurance tested Class V (space level) products.

16 of Intersil radiation-hardened ICs were onboard the December 5, 2014 maiden voyage of NASA's Orion spacecraft, also known as the uncrewed Exploration Flight Test 1. These rad-hard ICs are deployed in Orion's crew module, where they are used to support subsystems for mission critical applications in power distribution, navigation and flight control, and in the inertial measurement unit.

The low dose rate ionizing dose response of semiconductors has become a key issue in space applications. We are addressing this changed market by introducing wafer by wafer low dose rate acceptance testing as a complement to current high dose rate acceptance testing.
