Nexperia Samples New 650V GaN FETs
Next generation high voltage GaN technology targets automotive, 5G and data centre applications
Nexperia has announced a new range of GaN FET devices featuring next-gen high-voltage GaN HEMT H2 technology in both TO-247 and the company's proprietary CCPAK surface mount packaging. Devices achieve superior switching FOMs and on-state performance with improved stability, and simplify application designs thanks to their cascode configuration which eliminates the need for complicated drivers and controls.
The new GaN technology employs through-epi vias, reducing defects and shrinking die size by around 24%. RDS(on) is also reduced to just 41 mΩ (max., 35 mΩ typ. at 25degC) with the initial release in traditional TO-247, with high threshold voltage and low diode forward voltage. The reduction will further increase, to 39 mΩ (max., 33 mΩ typ. at 25 degC) with CCPAK surface-mount versions. Because the parts are configured as cascode devices, they are also simple to drive using standard Si MOSFET drivers. Both versions meet the demands of AEC-Q101 for automotive applications.
Dilder Chowdhury, Nexperia's GaN strategic marketing director commented: “Customers need a highly-efficient, cost-effective solution for high power conversion at 650 V and around the 30-40 mΩ RDS(on), where applications include on-board chargers, DC/DC converters and traction inverters in electric vehicles, and industrial power supplies in the 1.5-5 kW range for titanium-grade rack mounted telecoms, 5G and data centres. Nexperia continues to invest in the development and expansion of its range of products using next generation GaN processes, initially releasing traditional TO-247 versions and bare die format for power module makers, followed by our high-performance surface mount CCPAK packages."
Nexperia's CCPAK surface mount packaging adopts Nexperia's copper-clip package technology to replace internal bond wires. This reduces parasitic losses, optimizes electrical and thermal performance, and improves reliability. CCPAK GaN FETs are available in top- or bottom-cooled configurations making them very versatile and help further improving heat dissipation.
650 V GAN041-650WSB in TO-247 and GAN039-650NBB in CCPAK are sampling now.
