Enhanced Thermal Performance with GaN Power Packages for CGD Power ICs

CGD has introduced two innovative packages designed to enhance the performance and flexibility of their ICeGaN GaN power ICs. The DHDFN-9-1 (Dual Heat-spreader DFN) features a thin, dual-side cooled design with wettable flanks for easy optical inspection. With a compact 10- x 10-mm footprint and low thermal resistance, this package allows for bottom-side, top-side, and dual-side cooling options, surpassing the commonly-used TOLT package in various configurations.

The BHDFN-9-1 (Bottom Heat-spreader DFN) is a bottom-side cooled package that also boasts wettable flanks for simplified inspection. With a thermal resistance of 0.28 K/W, this package matches or exceeds the performance of leading devices in the market. Despite its smaller size compared to the TOLL package, the BHDFN maintains a similar footprint, enabling seamless integration with TOLL-packaged GaN power ICs.

Nare Gabrielyan, Product Marketing Manager at CGD, emphasized the strategic importance of these new packages in empowering customers to leverage ICeGaN GaN power ICs at higher power levels. Gabrielyan highlighted the growing demand for power-dense and efficient solutions in applications such as servers, data centers, inverters, motor drives, and micro-inverters. The ruggedness, reliability, and ease of integration offered by the new packages align with the evolving needs of these demanding applications.

Enhanced thermal resistance performance delivers multiple advantages to users. By enabling higher power output at the same RDS(on) level, the new packages contribute to improved efficiency and reduced system costs. Lower operating temperatures not only enhance reliability but also extend the lifespan of devices. Additionally, designers can opt for cost-effective solutions without compromising power output, thanks to the flexibility provided by the new packages.

Attendees at the upcoming PCIM exhibition in Nuremberg, Germany, will have the opportunity to witness the unveiling of these cutting-edge packages for the first time. For more information on CGD's latest offerings, visit www.camgandevices.com.
