Hi-Rel discrete devices provide radiation-tolerant, high-efficiency power-switching solutions for mission-critical space and high-reliability applications. Our portfolio includes discrete GaN FETs and GaN-based power stages, delivering exceptional efficiency, fast switching speeds, and high power density for power conversion, motor control, and high-speed switching applications. Designed to withstand SEE and TID effects, these GaN solutions enable compact, lightweight, and highly efficient power designs, ensuring reliable operation in the harshest aerospace and defense environments.
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, JANS, and radiation-tolerant space plastic products that are revolutionizing the Hi-Reliability and space marketplaces.
