These devices offer lower resistance and gate charge and enable faster power supply switching frequencies resulting in higher power densities, higher efficiencies, and more compact and lighter weight circuitry for critical spaceborne missions. Gallium nitride is inherently radiation tolerant, making these GaN-based devices a reliable, higher performing power transistor option for space applications.
Applications benefiting from these products include power supplies for satellites and mission equipment, light detection and ranging (lidar) for robotics and autonomous navigation and rendezvous docking, motor drives for robotics and instrumentation, and ion thrusters for satellite orientation and positioning, as well as interplanetary propulsion of low-mass robotic vehicles.
The EPC7014, a 60 V, 340 mΩ, 4 APulsed, rad-hard eGaN FET in a tiny 0.81 mm2 footprint, is the first in what will be a wide-range family of rad-hard transistors and integrated circuits. The EPC7014 has a total dose rating greater than 1 Mrad and SEE immunity for LET of 85 MeV/(mg/cm2). These devices are offered in a chip-scale package, same as the commercial eGaN FET and IC family.
Packaged versions will be available from EPC Space.
