Toshiba launches automotive MOSFET with industry-leading on-resistance



TK1R4S04PB 40V N-channel MOSFET

Toshiba Electronics has expanded its family of UMOS9 MOSFETs with the addition of a new 40V N-channel MOSFET housed in the advanced DPAK+ package. The new TK1R4S04PB has achieved AEC-Q101 qualification and is designed for automotive motor control applications such as water pumps, fuel pumps, oil pumps, fans, EPS and DC/DC converters.

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

The DPAK+ packaging is compatible with standard DPAK designs, measures just 6.5mm by 9.5mm 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.
