GaN Transistors Bring Newest Rad Hard Technology to Demanding Space Applications

GaN Transistors Bring Newest Rad Hard Technology to Demanding Space Applications

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

EL SEGUNDO, Calif.— April 2023 — EPC announces the introduction of two new radiation-hardened GaN FETs. The EPC7020 is a 200 V, 11 mΩ, 170 APulsed, rad-hard GaN FET in a small 12 mm2 footprint. The EPC7003 is a 100 V, 30 mΩ, 42 APulsed, rad-hard GaN FET in a tiny 1.87 mm2 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/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.

GaN Powers Small Satellites

GaN Powers Small Satellites

Small satellites bring a more cost-effective approach to low-Earth-orbit (LEO) missions, helping to deliver low-cost internet access across the globe. For this application, GaN FETs partnered with a radiation tolerant pulse width modulation controller and GaN fet driver allow more efficient switching, higher frequency operation, reduced gate drive voltage and smaller solution sizes compared to the traditional silicon counterparts.
