EPC Launches Rad Hard GaN Transistors for Space Applications

Article By : Efficient Power Conversion

EPC has expanded its family of rad-hard GaN products to address a multitude of critical spaceborne and other high-reliability applications.

Efficient Power Conversion (EPC) has expanded its family of radiation-hardened (rad-hard) gallium nitride (GaN) products for power conversion solutions with two new devices rated at 100V and 200V to address a multitude of critical spaceborne and other high-reliability applications.

The EPC7020 is a 200V, 11mΩ, 170APulsed rad-hard GaN FET in a small 12mm2 footprint, while the EPC7003 is a 100V, 30mΩ, 42APulsed, rad-hard GaN FET in a 1.87mm2 footprint. Both devices have a total dose radiation rating greater than 1,000K Rad (Si) and SEE immunity for LET of 83.7MeV/mg/cm2 with VDS up to 100% of rated breakdown.

These new devices, along with the rest of the Rad Hard family, EPC7019, EPC7014, EPC7004, EPC7018, EPC7007, are offered in a chip-scale package, the same as the commercial eGaN FET and IC family. Packaged versions will be available from EPC Space.

eGaN FETs and ICs are smaller, operate 40 times better electrically, and are lower cost than the Rad Hard silicon devices typically used in high reliability and space applications. GaN devices also support higher total radiation levels and SEE LET levels than 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, satellites including those for LEO and GEO orbits, and avionics.

“The Rad Hard product family ranges from 40V to 200V and from 4A to 530A covering a wide range of applications in harsh environments, such as space including interplanetary scientific missions, high altitude flight, and other high reliability military applications,” said Alex Lidow, CEO and co-founder of EPC.

The EPC7020 and EPC7003 are available for engineering sampling now.
