Nexperia establishes new category of application-specific FETs to optimize performance

     Nexperia, a high-volume production specialist in semiconductor basic components, has responded to industry needs by defining a new set of MOSFET products to maximize performance. Application-specific FETs (ASFETs for short) employ MOSFETs that provide optimized parameters for a specific application. Significant improvements can be achieved by focusing on specific applications.

     Nexperia offers the ASFET series for battery isolation, motor control, hot swap and Power over Ethernet (PoE) applications. The improvements that can be achieved with custom ASFETs vary by application, for example, for hot-swap applications, the safe operating area (SOA) can be increased by a factor of 3 to 5; for motor applications, the maximum current rating can exceed 300 A.

     Chris Boyce, Senior Director, Power MOSFETs Division at Nexperia commented: “As designers push performance boundaries, it is critical to understand how to use MOSFETs in their applications. There are over 100 parameters in a typical MOSFET data sheet, but in every project Usually only a few parameters are important. However, as the application changes, the important parameters also change. At Nexperia, we determine the performance of each element in the product, including: core wafer technology, chip design, Packaging, manufacturing and testing procedures. By putting the needs of a specific application at the center of our consideration, we can choose to optimize the most important parameters in a specific application, often at the expense of other less relevant parameters. Essentially, We combine proven MOSFET expertise with a broad understanding of the application, so we can tailor and deliver the best performing products for a specific application or function."

     With the upcoming release of a new automotive product family, the ASFET category will be further enhanced to provide guaranteed repeated avalanche tolerance for driving inductive loads. Boyce added: "We are constantly seeking to deepen our understanding of specific applications, often working hand-in-hand with our customers. By providing our talented engineers with detailed application requirements, we will usher in new and exciting innovation opportunities, numerous advances in ASFET technology. Coming soon."
