E-mode GAN FETs for low and high-voltage applications

By augmenting its cascode offering with seven new e-mode devices, Nexperia now provides designers with the optimum choice of GaN FETs from a single supplier alongside its substantial portfolio of silicon-based power electronics components.

Nexperia’s new portfolio includes five 650V rated e-mode GaN FETs (with RDS(on) values between 80 and 190mΩ) in a choice of DFN 5 x 6mm and DFN 8 x 8mm packages. They improve power conversion efficiency in high-voltage, low-power (less than 650V) datacom/telecom, consumer charging, solar, and industrial applications. They can also be used to design brushless DC motors and micro server drives for precision with higher torque and more power.

Nexperia now also offers a 100V (3.2mΩ) GaN FET in a WLCSP8 package and a 150V (7mΩ) device in a FCLGA package. These devices are suitable for various low-voltage (less than 150V), high-power applications to deliver, for example, more efficient DC/DC converters in data centres, faster charging (e-mobility and USB-C), smaller LiDAR transceivers, lower noise class D audio amplifiers, and more power dense consumer devices like mobile phones, laptops, and games consoles.

GaN FETs offer high power efficiency with a compact solution size in many power conversion applications, features which substantially reduce the bill of materials (BOM). As a result, GaN devices are increasingly entering mainstream power electronics markets, including server computing, industrial automation, consumer, and telecom infrastructure.

GaN-based devices offer the fastest transition/switching capability (highest dv/dt and di/dt) and deliver superior efficiency in low- and high-power conversion applications. The switching performance of Nexperia’s e-mode GaN FETs is attributable to very low Qg and QOSS values, while their low RDS(on) enables more power-efficient designs.

With this release Nexperia now supply a broad offering of GaN FET products to suit the wide range of power applications best suited to the technology, including cascode devices for high-voltage, high-power applications, 650V e-mode devices for high-voltage, low-power applications and 100/150V e-mode devices for low-voltage, high-power applications.

Furthermore, Nexperia e-mode GaN FETs are fabricated on an 8” wafer-line for increased capacity and qualified for industrial applications according to JEDEC standard. The expansion of its GaN device offering is a testament to Nexperia’s commitment to quality silicon and wide-bandgap technologies.
