• Have increased robustness and reliability for high-power-density applications
• Offers up to 13 per cent low R_DS(on) and up to 50 per cent high current-carrying capability

Infineon Technologies has expanded its StrongIRFET™ 40-60 V MOSFET product family with the addition of three new devices in D²PAK 7pin+ package. They are aimed for battery-powered applications including, battery-powered tools, battery management systems and low-voltage drives.

In comparison to the standard D²PAK 7pin package, the new family offers up to 13 per cent lower R_DS(on) and up to 50 per cent higher current-carrying capability. This increases both robustness and reliability for high-power-density applications that require high efficiency. For instance, the benchmark IRL40SC240 is a 40V device that has an R_DS(on) of 0.65 mΩ and current-carrying capability of 360A.

New but same footprint

The D²PAK 7pin+ package is optimized to hold a die with an increased area of up to 20 per cent while sharing the same footprint and pinout as a standard D²PAK 7pin. Thus, it can easily replace the traditional D²PAK 7pin and H²PAK packages. The product family offers both normal-level and logic-level gate drives as well for providing designers flexibility in their drive schemes.

This expansion further enhances the options for selecting the ideal power device for many design challenges. Additionally, the interchangeable pinout options of the new package allow for unmatched design flexibility.

The StrongIRFET in the D²PAK 7pin+ package is available now.
