The results of the development of power switching transistors based on epitaxial gallium nitride heterostructures to create an energy-efficient conversion technique are presented. The developed powerful GaN transistor operates in enrichment mode with unlocking threshold voltage Vth = +1.2 V and a maximum drain-source current Ids = 0.15 A/mm at the drain-source voltage Vds = +8 V. The drain-source breakdown voltage in the closed state is Vb = 300 V at the drain-source distance Lds = 8.5 μm and drain-source voltage Vds = 0 V.
