Renesas‘ (formerly Intersil) history and experience in the space and defense industries span almost seven decades beginning with the founding of Radiation, Inc. in 1950. Today, Intersil continues to support and release new SMD and Class-V radiation hardened products for the Defense, Hi-Reliability, and Space marketplaces.

Renesas is also broadening their portfolio 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. Fleets of hundreds of small satellites will create mega-constellation networks to deliver broadband Internet links from low Earth orbit (LEO) to every corner of the globe.

Renesas‘ rad-tolerant plastic packaging flow leverages the company’s more than 60 years of spaceflight experience developing products for extremely harsh environments. The upfront radiation effects characterization and AEC-Q100 automotive-like qualification gives customers the utmost confidence to design Intersil radiation-tolerant plastic parts into cost-sensitive small satellites for LEO mission profiles up to five-years.

By leveraging Renesas‘ latest technology for the consumer marketplace, Renesas’ Intersil space products group is releasing Class V and radiation tolerant products that are revolutionizing the Hi-Reliability and Space marketplaces.

Renesas’ Approach to Radiation Environments in Space: TID (Total Ionizing Dose) TID is the progressive, long-term ionizing radiation damage caused by protons, electrons and other sources. Total ionizing dose testing of semiconductor components has historically been performed at ‘qualification’ dose rates in the 50 – 300rad(Si)/s. Modern sub-micron technologies tend to be more resistant to total dose effects. Renesas’ approach: TID hardness tested and guaranteed on a wafer by wafer basis to MIL-STD-883 Method 1019 using in-house Gammacell 220™ 60Co irradiator.


SEE (Single-Event Effects)

The intense heavy ion environment encountered in space applications can cause a variety of effects in electronic circuitry, including Single-Event Transient (SET), Single-Event Latchup (SEL) and Single-Event Burnout (SEB). These Single-Event Effects (SEE) can lead to system-level performance issues including disruption, degradation and destruction.

Renesas’ approach: SEE characterizations are performed at Texas A&M and complete reports can be found at


ELDRS (Enhanced Low Dose Rate Sensitivity)

Researchers have noted strong dose rate dependence in the total dose response of bipolar analog integrated circuits. Many industry-standard devices show severe degradation of key parameters when irradiated at very low dose rates. The de facto standard for low dose rate is 0.01 rad(Si)/s, which is now included in MIL-STD-883 Method 1019.

Renesas’ approach: Starting in 2011, Renesas performs wafer-by-wafer production testing qualification at both low and high dose rate under biased and unbiased conditions. Renesas constructed a vault-type low dose rate irradiator specifically to support this activity. Baseline ELDRS testing continues, and complete reports can be found on the Renesas website. Renesas parts released on this new low dose flow have an EH designation (vs. RH).
