New 40V N-channel Power MOSFETs with Improved Thermal Performance

In August, Toshiba starts mass production and shipments of its 40V N-channel power MOSFETs - “TPWR7904PB” and “TPW1R104PB”, for automotive applications. They will be available in DSOP Advance(WF) packages that comes with double-sided cooling, low resistance, and small size.

The power MOSFETs secure high heat dissipation and low On-resistance characteristics by mounting a U-MOS IX-H series chip, which comes with the latest trench structure, into a DSOP Advance(WF) package. It enables the heat generated by conduction loss to be effectively dissipated, improving the flexibility of thermal design.

The U-MOS IX-H series MOSFETs also deliver lower switching noise than Toshiba’s previous U-MOS IV series, contributing to lower EMI. The DSOP Advance(WF) package has a wettable flank terminal structure.

The devices are qualified for AEC-Q101, thus suitable for automotive applications; and comprise features such as double-sided cooling package with top plate and drain, improved AOI visibility due to wettable flank structure, and low On-resistance and low noise characteristics. They can be used in automotive applications like Electric power steering, Load switches and Electric pumps.
