E-mode GAN fets are suitable for both low- and high-voltage applications

Nexperia has released its first power GaN fets in e-mode (enhancement mode) configuration for low (100/150V) and high (650V) voltage applications. By augmenting its cascode offering with seven e-mode devices, Nexperia now provides  a choice of GaN fets.

Nexperia’s portfolio includes five 650V rated e-mode GaN fets (with RDS(on) values between 80 mOhm and 190 mOhm) in a choice of DFN 5 x 6mm and DFN 8 x 8mm packages. They are claimed to improve power conversion efficiency in high-voltage, low-power (<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.

The company is also offering a 100V (3.2 mOhm) GaN fet in a WLCSP8 package and a 150V (7 mOhm) device in a FCLGA package. These devices are claimed to be suitable for low-voltage (<150 V), 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 such as mobile phones, laptops and games consoles.

GaN fets are said to offer the highest power efficiency with the most compact solution size in many power conversion applications, features that reduce the bill of materials (BOM). As a result, GaN devices are claimed to be entering mainstream power electronics markets, including server computing, industrial automation, consumer, and telecom infrastructure. According to the company, 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) is claimed to enable more power-efficient designs.

Nexperia e-mode GaN fets are fabricated on an 8-inch wafer-line for increased capacity and qualified for industrial applications, according to JEDEC standard.
