Nexperia establishes new application specific FET category

1 min read

Nexperia has defined a new MOSFET product group. Application Specific FETs (ASFETs) will feature MOSFETs with optimised parameters for specific applications.

By focusing on individual applications, significant improvements can now be offered.

Nexperia said that it will be offering ASFET families for battery isolation, motor control, hot-swap and Power over Ethernet (PoE) applications.

Defining the improvements that these tailored ASFETs can offer includes a 3x – 5x improvement in Safe Operating Area (SOA) for hot-swap applications, and maximum current ratings in excess of 300 A for motor applications.

Commenting Chris Boyce, Senior Director for the Power MOSFETs Group at Nexperia, said, “As designers push the boundaries of performance, it is crucial to understand how the MOSFET will be used in the application. There are 100+ parameters on a regular MOSFET datasheet but usually only a few are critical in each project. However, as the applications change, so do the critical parameters. We determine the performance of every element of our products; the core silicon technology, the chip design, the package and the manufacturing & test procedures.

“By keeping individual application requirements front and centre of our thinking, we can choose to optimise the parameters that matter most in a particular use-case, often at the expense of others of less relevance.”

The ASFET category will be further enhanced with the imminent release of a new family of automotive products with guaranteed repetitive avalanche performance for driving inductive loads.
