Infineon Technologies AG introduces the new CoolGaN™ Transistor 700 V G4 product family. The devices are highly efficient for power conversion in the voltage range up to 700 V. In contrast to other GaN products on the market, the input and output figures-of-merit of these transistors provide a 20% better performance, resulting in increased efficiency, reduced power losses, and more cost-effective solutions. The combination of electrical characteristics and packaging ensures maximum performance in many applications such as consumer chargers and notebook adapters, data center power supplies, renewable energy inverters, and battery storage.

The product series comprises 13 devices with a voltage rating of 700 V and on-resistance range from 20 mΩ to 315 mΩ. The increased granularity in device specification, combined with a wide range of industry standard package options including PDFN, TOLL, and TOLT allow R_DS resistance and packages to be selected according to application requirements. As a result, both electrical and thermal system performance can be optimized and implemented in the most cost-effective solution.

The devices are characterized by a fast turn-on and turn-off speed and minimal switching losses. The on-resistance range enables power systems from 20 W to 25,000 W. In addition, the 700 V E-mode with the industry's highest transient voltage of 850 V increases the reliability of the overall system as it offers greater robustness against anomalies in the user environment such as voltage peaks.

Availability

The CoolGaN Transistor 700 V G4 products in TOLL, PDFN 5x6 and 8x8 packages are available now, more variety in R_DS(on) as well as the TOLT package will follow later this year. Samples will be available in August 2024.
