Mid-voltage power MOSFETs feature high current capabilities

11 July 2007 Power Electronics / Power Management

Ixys has released a new line of high current mid-voltage power MOSFETs in versions ranging from 55 V to 100 V, featuring ultra-low Rds(on).

The new power MOSFETs capitalise on the benefits of proprietary ISOPLUS packaging technology, in this case the ISOPLUS i5-Pak. The principal feature of this set of i5-Pak MOSFETs arises from the joining of two IXYS mid-voltage MOSFETs with the reliable, high power handling capability of IXYS discrete ISOPLUS i5-Pak. Silicon current handling has outpaced the ability of most traditional discrete packaging, which typically limits steady state current to 75 A. In this case, the ISOPLUS i5-Pak is equipped with five heavy-gauge leads to provide a dual die, common-gate configuration with joined copper webs and backside heatsinking, all of which conservatively improve the package rating to 150 A for the two dice.

All IXYS ISOPLUS packages are manufactured with internal direct-copperbonded (DCB) isolation and are UL certified and provide integral backside case isolation. The IXTL2x240N055T (rated at 55 V, Rds(on) of 4,4 mΩ/MOSFET) and IXTL2x180N10T (rated at 100 V, Rds(on) of 7,4 mΩ/MOSFET) are just some examples.
