EPC Space announces the launch of the EPC7030MSH, a radiation-hardened (RH) 300 V gallium nitride (GaN) FET that delivers unmatched performance for high-voltage, high-power space applications, including next-generation satellite power plants and electric propulsion systems.

As satellite platforms require higher voltage buses to support growing power demands and advanced solar array technologies, the EPC7030MSH addresses a critical need for efficient, compact, and robust front-end power conversion.

With the lowest RDS(on) and gate charge in its class, the EPC7030MSH delivers the highest power current rating among all 300 V rad-hard GaN FETs currently on the market. This makes it ideal for front-end DC-DC converters that must operate under stringent thermal and radiation constraints.

“The EPC7030MSH 300V RH GaN FET delivers high current and rad-hard reliability, meeting the rigorous demands of higher-voltage space power architectures and simplifying thermal design for our customers,” said Bel Lazar, CEO of EPC Space.

Key Features:

  • Rated for 300 V operation at LET = 63 MeV, and 250 V at LET = 84.6 MeV
  • Lowest RDS(on) and QG of any 300 V rad-hard GaN FET
  • Highest current rating in its voltage class
  • FSMD-M hermetic surface-mount package optimized for conduction cooling and increased creepage distance
  • Compatible with existing GaN gate drivers

Target Applications:

  • Front-end DC-DC converters in satellite power systems
  • Power conversion for higher voltage distribution buses
  • Electric propulsion platforms requiring compact, high-performance switching

The EPC7030MSH is part of EPC Space’s ongoing mission to deliver space-grade Radiation Hardened GaN solutions that outperform silicon Radiation Hardened MOSFETs in efficiency, size, and thermal management—enabling more capable, reliable, and scalable satellite systems.

For 500-unit quantities engineering models are priced at 236 USD, and Rad Hard space qualified are priced at 349 USD.
