TOSHIBA LAUNCHES AUTOMOTIVE 40V N-CHANNEL POWER MOSFETS WITH NEW PACKAGE

Toshiba Electronic Devices & Storage Corporation has launched two automotive 40V N-channel power MOSFETs, “XPJR6604PB” and “XPJ1R004PB,” that use Toshiba’s new S-TOGL™ (Small Transistor Outline Gull-wing Leads) package with U-MOS IX-H process chips.

Safety-critical applications like autonomous driving systems ensure reliability through redundant design, with the result that they integrate more devices and require more mounting space than standard systems. Accordingly, advancing size reductions in automotive equipment require power MOSFETs that can be mounted at high current densities.

The combination of the S-TOGL™ package and Toshiba's U-MOS IX-H process achieves a significant On-resistance reduction of 11% against Toshiba's TO-220SM (W) package product, which has the same thermal resistance characteristics. The new package also cuts the required mounting area by approximately 55% against the TO-220SM(W) package. On top of this, the 200A drain current rating of the new package is higher than Toshiba’s similarly sized DPAK + package (6.5mm×9.5mm), enabling high current flow. Overall, the S-TOGL™ package realizes high-density and compact layouts, reduces the size of automotive equipment, and contributes to high heat dissipation.

Since automotive equipment is used in extreme temperature environments, the reliability of surface mounting solder joints is a critical consideration. The S-TOGL™ package uses gull-wing leads that reduce mounting stress, improving the reliability of the solder joint.
