High-reliability MOSFETs target battery-powered applications

By Gina Roos, editor-in-chief

Infineon Technologies AG has expanded its StrongIRFET 40- to 60-V MOSFET product family with the addition of three new devices in the D²PAK 7pin+ package. Delivering extremely low R_DS(on)  and high current-carrying capability, these new power MOSFETs combine robustness and reliability for high-power-density applications that call for high efficiency. Target applications include battery-powered tools, battery management systems, and low-voltage drives.

The new D²PAK 7pin+ package adds another option to the StrongIRFET family, with the interchangeable pinout options delivering greater design flexibility. In addition, the package is optimized to hold a die with an increased area of up to 20% while sharing the same footprint and pinout as a standard D²PAK 7pin, said Infineon. This means it can replace the traditional D²PAK 7pin and H²PAK packages.

The new family offers up to 13% lower R_DS(on)  and up to 50% higher current-carrying capability when compared to previous-generation devices.  For example, the benchmark IRL40SC240 is a 40-V device with an R_DS(on)  of 0.65 mΩ and current-carrying capability of 360 A.

In addition, the product family offers both normal- and logic-level gate drive for greater flexibility in drive schemes. The StrongIRFET MOSFETs in the D²PAK 7pin+ package are available now.
