150V UltraFET MOSFET

December 12, 1999 by Jeff Shepard

Intersil Corporation (Palm Bay, FL) recently introduced its new 150V UltraFET MOSFET, the HUF75842. The HUF75842 is a 42A, 42 milliohm Rds(on) device designed for use in dc/dc converters, motor control applications and uninterruptible power supplies (UPSs). Intersil claims that the HUF75842 family of devices offers dc/dc converter engineers, who require MOSFETs with breakdown voltages higher than 100V, alternatives to the standard 200V MOSFETs currently available on the market. Optimal trade off between Rds(on), gate charge and switching speed allow engineers to employ the HUF75842 as a means of improving overall efficiency in dc/dc converter applications. The HUF75842 features a maximum gate charge of 92nC and typical fall time (tf) and turn off delay (tdoff) of 34 nanoseconds (nS) and 47nS respectively.
