Automotive power FET with 1.35mΩ on-resistance

February 19, 2016 // By Graham Prophet
This AEC-Q101 qualified 40V DPAK+ MOSFET claims lowest on resistance of just 1.35mΩ at 10V drive. In Toshiba’s UMOS9 MOSFET series, it is packaged in DPAK+. Applications include automotive motor control applications such as water pumps, fuel pumps, oil pumps, fans, EPS; and DC/DC converters.

This MOSFET achieves R DS(ON) = max1.35mΩ at VGS=10V – the lowest R DS(ON) of any MOSFET currently available. It does so by combining UMOS9 trench technology that minimises R DS(ON) x A, with the DPAK+ package that reduces package resistance compared to conventional DPAK packaging.

DPAK+ packaging is compatible with standard DPAK designs, measures 6.5 by 9.5 mm and features copper clip technology that replaces the traditional bondwire connections with copper clips that have a large contact area and are attached directly to the chip metallisation. The MOSFET is also enhanced compared with previous generations in terms of Electro-Magnetic Capability (EMC) and switching performance.
