The new GaN technology employs through-epi vias, reducing defects and shrinking die size by around 24%. R_DS(on) is also reduced to just 41 mΩ (max., 35 mΩ typ. at 25 °C) 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 °C) 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 R_DS(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 datacenters. 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 proven innovative 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. More information including product specs and datasheets is available at www.nexperia.com/gan-fets.
