EPC Launches 40V Rad Hard GaN FETs That Set New Performance Standards for Demanding Space Applications

PublishTime： 2023-07-21 Article Source：EPC News

Efficient Power Conversion (EPC) expands its family of radiation-hardened (rad-hard) gallium nitride (GaN) products for power conversion solutions with two new 40V devices rated at 62A and 250A to address critical spaceborne and other high-reliability applications.

EPC announces the introduction of two new 40V-rated radiation-hardened GaN FETs. EPC7001 is a 40V, 4mΩ, 250A_Pulsed, rad-hard GaN FET in a small 7mm² footprint. EPC7002 is a 40V, 14.5mΩ, 62A_Pulsed, rad-hard GaN FET in a tiny 1.87mm² footprint. Both devices have a total dose radiation rating greater than 1,000K-Rad (Si) and SEE immunity for LET of 83.7 MeV/mg/cm²with V_DS up to 100% of rated breakdown. These new devices, along with the rest of the Rad Hard family, are offered in a chip-scale package. Packaged versions are available from EPC Space.

EPC’s eGaN FETs and eGaN ICs offer a higher-performing alternative to conventional rad hard silicon devices for high reliability and space applications. EPC’s Rad hard devices are significantly smaller, have 40 times better electrical performance, and lower overall cost than rad hard silicon devices. Moreover, EPC’s rad-hard devices exhibit superior resistance to radiation, supporting higher total radiation levels and SEE LET levels compared to traditional silicon solutions.

Applications benefiting from the performance and fast deployment of these devices include DC-DC power converters, motor drives, lidar, deep probes, and ion thrusters for space applications. They are particularly well-suited for satellites operating in both Low Earth Orbit (LEO) and Geosynchronous Earth Orbit (GEO), as well as avionics systems.

“The Rad Hard product family provides unparalleled performance and reliability, coupled with significant space heritage for more efficient and robust systems covering a wide range of applications in harsh environments, such as space and other high-reliability military applications”, said Alex Lidow, CEO, and co-founder of EPC.
