Gallium nitride and silicon carbide are designated wide-bandgap (WBG) semiconductors based on the energy required to shift electrons in these materials from the valence to the conduction band — about 3.2 eV for SiC and 3.4 eV for GaN, compared with just 1.1 eV for silicon. The WBG properties lead to a higher applicable breakdown voltage, which can reach up to 1,700 V in some applications. At this year’s digital only PCIM Europe, held in May, several companies showed their latest innovations in GaN and SiC and offered insights on where WBG technology is headed.

Efficient Power Conversion (EPC) introduces a new family of radiation-hardened (rad-hard) gallium nitride (GaN) products for power conversion solutions in critical spaceborne and other high reliability environments.
EL SEGUNDO, Calif.— June 2021 — EPC announces the introduction of a new family of radiation-hardened gallium nitride transistors and integrated circuits. With higher breakdown strength, faster switching speed, higher thermal conductivity and lower on-resistance, power devices based on GaN significantly outperform silicon-based devices. The lower resistance and gate charge 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 also inherently radiation tolerant, making GaN-based devices a reliable, higher performing power transistor option for space applications.
