ROHM Semiconductor Unveils Advanced 650V GaN HEMT Technology

Introducing ROHM's Latest 650V GaN HEMT Innovations

ROHM Semiconductor has recently unveiled its highly anticipated 650V GaN HEMT semiconductor device. Marked by its innovative TO-Leadless (TOLL) packaging, this new product symbolizes a significant advancement in the company’s efforts to impact various power-intensive applications positively. Designed to optimize heat dissipation, this compact package accommodates high current capacities and superior switching performance, making it an ideal choice for industrial and automotive sectors where efficient power management is critical.

Meeting the Power Efficiency Challenge

As the global demand for efficient power solutions increases, industries are presented with the challenge of drastically improving the efficiency of motors and power supplies. Power devices are central to addressing energy consumption—especially since these systems account for a significant portion of the world's electricity usage. New semiconductor materials, specifically Silicon Carbide (SiC) and Gallium Nitride (GaN), are paving the way for enhanced power performance, which is crucial for achieving a more sustainable and decarbonized world.

Evolution of ROHM's GaN Technology

ROHM began its journey into the world of GaN technology with the production of its first-generation 650V GaN HEMTs in early 2023. This was quickly followed by the introduction of power stage ICs, which combine a gate driver with a GaN HEMT into a single, efficient package. The new release, featuring second-generation elements within the TOLL package, builds on the already robust DFN8080 package. This expansion is tailored to meet the rising market demand for smaller, more efficient solutions in high-power applications.

Key Features and Benefits of the New GaN Device

The newly launched 650V GaN HEMTs incorporate advanced GaN-on-Silicon technology, allowing for remarkable performance metrics. With an emphasis on reducing ON-resistance and output charge, these devices contribute significantly to energy efficiency in high-voltage and rapid-switching requirements.

Mass Production and Strategic Collaborations

To facilitate mass production, ROHM has drawn on its proprietary technology and industrial expertise. The vertically integrated production system enables meticulous design and planning while ensuring high-quality output. Currently, the front-end processing is managed in partnership with the renowned Taiwan Semiconductor Manufacturing Company (TSMC), while back-end operations are conducted by ATX Semiconductor (Weihai) Co., Ltd., an OSAT provider. This collaborative approach is expected to yield automotive-grade GaN devices as well.

Future Prospects in Automotive Applications

With the automotive sector increasingly inclined towards GaN technology, ROHM is set to expedite the introduction of automotive-grade devices. With anticipated industry growth, these partnerships are pivotal to ensuring swift development and integration into various automotive applications.
Liao Hongchang, Director and General Manager of ATX, expressed enthusiasm over the partnership with ROHM. He emphasized the importance of combining manufacturing expertise and capability to drive innovation and sustainability across industries.

Broader Applications of the 650V GaN HEMT

This groundbreaking product will find its place in a variety of applications, including but not limited to:

• Power supplies designed for servers and communication base stations.
• Industrial equipment that requires high power handling capabilities.
• AC adapters, such as USB chargers, and energy storage systems.
• Power supply systems capable of outputs ranging from 500W to 1kW.
