Renesas Launches New Radiation-Hardened Plastic ICs for Satellites in Medium and Geosynchronous Earth Orbits
Renesas Electronics Corporation, a premier supplier of advanced semiconductor solutions, launched a new line of plastic-packaged radiation-hardened devices for satellite power management systems.

The new ICs also complement the radiation-tolerant plastic-package ICs Renesas introduced in 2017 for smallsats in Low Earth Orbit. Together, Renesas’ plastic IC lineup supports multiple orbit ranges, providing the radiation performance and optimal cost balance required for a variety of satellite subsystems and payloads.
“With every new mission, customers want more functionality, which requires larger satellite payloads and has traditionally translated into increased SWaP for the satellite systems,” said Philip Chesley, Vice President, Industrial and Communications Business Division at Renesas. “With Renesas’ new ICs, customers can enjoy the SWaP advantages of plastic packaging to save up to 50 percent of the board area compared to ceramic-packaged devices, while maintaining the reliability and radiation assurance required for higher orbit missions with lifespans ranging up to and beyond 15 years.”
Traditionally, radiation-hardened ICs were almost exclusively produced using hermetically sealed ceramic packages, which achieved the required reliability but had significant tradeoffs in terms of size and weight. The new Renesas rad-hard plastic ICs help customers reduce their electronics footprint and cost without compromising performance.
To ensure the plastic ICs adhere to the highest quality for operation in harsh space environments, the new devices feature QMLV-like production level testing, and all devices will undergo Radiation Lot Acceptance Testing (RLAT).
The production test flow includes 100 percent CSAM, X-Ray, Temperature Cycling, Static and Dynamic Burn In, and visual inspection, and aligns with the SAE AS6294/1 standard for plastic encapsulated microelectronics in space. Additional screening includes Lot Assurance Testing per assembly and wafer lot product for HAST, Life Testing, and Moisture Sensitivity. Renesas offers power management products that can be used in multiple power distribution architectures.
The ISL71610SLHM, ISL73033SLHM and ISL71001SLHM are available now. The ISL71710SLHM will be available in September 2021 and the ISL71001SEHM will be available in Q4 2021.
