RS7E200BG is a 30V mosfet optimised for both secondary-side ac-dc conversion and hot-swap controllers in 12V enterprise server power supplies.
RS7N200BH is an 80V mosfet optimised for secondary ac-dc conversion in 48V server power supplies, as is RS7N160BH.
“The DFN5060-8S package increases the internal die size area by approximately 65% compared to the conventional 5 x 6mm HSOP8 package,” said Rohm. “As a result, the 30V RS7E200BG and 80V RS7N200BH achieve on-resistances of 0.53mΩ and 1.7mΩ respectively with 10V [gate drive].”

Within the package, the clip design has been optimise to to enhance heat dissipation.
“RS7E200BG at 30V achieves an SOA [safe operating area] tolerance of over 70A at a pulse width of 1ms and Vds = 12V, which is twice that of the conventional HSOP8 package mosfets under the same conditions,” claimed the company.
