JAXA Collaborates with Power Diamond Systems for Space Applications of Diamond Semiconductors

In a significant move towards advancing aerospace technology, Power Diamond Systems (PDS), headquartered in Tokyo, Japan, has initiated a collaborative research agreement with the Japan Aerospace Exploration Agency (JAXA). The project aims to investigate the applicability of diamond semiconductor devices in the space and aviation sectors, focusing particularly on high-performance power MOSFETs that could withstand the extreme conditions of outer space.

Background and Research Objectives

The utilization of spacecraft has diversified in recent years, encompassing various applications such as space exploration, satellite communications, and Earth observation. This evolving landscape demands electronic components that offer enhanced performance and reliability, particularly in power conversion technologies. To meet these requirements, diamond semiconductors, which are anticipated to be the next generation of power semiconductor materials after silicon (Si), silicon carbide (SiC), and gallium nitride (GaN), are gaining considerable attention. Notably, these semiconductors exhibit remarkable traits such as high current capacity, high-voltage tolerance, high-temperature operation, and exceptional radiation resistance.

Power Diamond Systems has been at the forefront of developing diamond semiconductor technology for industrial applications and power infrastructure. Through this collaborative research initiative, PDS will leverage its established expertise in designing and manufacturing diamond power MOSFETs, merging it with JAXA's profound knowledge of environmental evaluation and aerospace systems. Together, they will explore future implementation scenarios for diamond semiconductors in space applications.

Comments from Power Diamond Systems CEO

Tatsuya Fujishima, CEO of Power Diamond Systems, expressed his enthusiasm regarding this collaboration. Since the company's inception in August 2022, the development of diamond semiconductor power devices and their integration into various applications has been a primary focus. Fujishima recognizes the aerospace sector as a promising field for the application of their technology, emphasizing that for over a year, PDS has engaged in technical evaluations and discussions with JAXA.

"This official commencement of collaborative research represents a deepening of our partnership with JAXA, and it is a recognition of the quality of our technological achievements and discussions, which have reached new heights," said Fujishima. He outlined the ambition to aim for the implementation of diamond power MOSFETs in spacecraft, establishing evaluation technologies resilient to the harsh space environment.

In the future, through this collaboration, both entities aspire to pioneer the utilization of diamond power MOSFETs in space applications, marking a historic milestone in the field of power electronics.
