Industry Impact:

  1. The collaboration between GaN semiconductor and end product manufacturers in developing JEP198 underscores the industry's commitment to establishing uniform standards for GaN technology. This not only enhances the confidence of power system manufacturers but also contributes to the overall advancement of wide bandgap (WBG) power technologies.

  2. Dr. Kurt Smith's statement regarding the rise of renewable energy and electrification emphasizes the critical role of GaN power semiconductors in addressing the efficiency demands of these sectors. The guideline for Reverse Bias Reliability Evaluation serves as a testament to the industry's dedication to improving confidence in GaN technology and its products.

JC-70 Committee:

  1. The formation and growth of the JC-70 committee, which now comprises over 80 member companies, signify the industry's concerted efforts to develop universal standards for WBG power technologies. The participation of global multinational corporations, technology startups, and industry experts from various regions highlights the collaborative nature of this standardization effort.

  2. The upcoming committee meeting in February 2024 presents an opportunity for interested companies worldwide to join JEDEC and contribute to this critical standardization effort, further solidifying the industry's commitment to advancing GaN and SiC semiconductors.

In conclusion, the publication of JEP198 and the activities of the JC-70 committee reflect a significant push towards standardizing and enhancing the reliability and performance of GaN power semiconductors. This development not only addresses the immediate needs of power electronics but also aligns with the broader trends in renewable energy, electrification, and the global transition towards more efficient and sustainable technologies.
