GaN Transistor 650V

E-mode HEMT

Taiwan Semiconductor introduces 650V Enhancement Mode GaN Transistors which are packaged in thermally efficient PDFN packages with small 5×6 & 8×8 mm footprint. These GaN Transistor products meet today’s high-power system requirements to achieve higher operating currents, higher efficiency, and smaller size and weight. The transistors, developed specifically for industrial, and renewable energy industries, feature the highest current GaN in production.
