• Single-channel isolated gate drivers in the 1ED301xMC121 series from Infineon are pin-compatible replacements for optocoupler-based designs. • They replicate optocoupler input characteristics, enabling drop-in use without control circuit changes, while using non-optical isolation internally to deliver higher CMTI and improved switching performance for SiC applications. • Their opto-emulator input stage uses two pins and integrates reverse voltage blocking, forward voltage clamping, and an isolated signal transmitter. • With CMTI exceeding 300 kV/µs, 40-ns propagation delay, and 10-ns part-to-part matching, the devices deliver robust, high-speed switching performance. • The series includes three variants-1ED3010, 1ED3011, and 1ED3012-supporting Si and SiC MOSFETs as well as IGBTs. • Each delivers up to 6.5 A of output current to drive power modules and parallel switch configurations in motor drives, solar inverters, EV chargers, and energy storage systems.
