Hi-Rel Digital Isolators

Renesas Hi-Rel digital isolators provide robust, radiation-tolerant signal isolation for mission-critical space and high-reliability applications. Designed for high-speed, low-latency communication, these isolators are ideal for use with RS-485 transceivers and other interface protocols, ensuring reliable data transmission in electrically noisy environments. Additionally, they can be paired with GaN FET drivers to create discrete bespoke power stages, delivering precise gate control, enhanced efficiency, and superior power management. Built to withstand radiation exposure and extreme operating conditions, these isolators enhance system robustness and electrical isolation in both communication and power applications.

Renesas offers products across many screening flows: QML-V, QML-V-equivalent, QML-P, QML-P-equivalent, and RT Plastic. Refer to product datasheets to determine which flows are applicable.
