Recommendation:
If you’re looking for alternatives that are close to the RHRP8120, DSEP8-12A (IXYS) and VS-8ETU12HN3 (Vishay) are solid choices. They share similar packaging, reverse voltage, and average current specifications, with DSEP8-12A offering slightly lower forward voltage at 8A and faster reverse recovery time.
If your application requires higher current, the DHG10I1200PA (IXYS) offers a higher current rating of 10A, making it more suitable for high-current applications.
