Gallium nitride (GaN) offers fundamental advantages over silicon. In particular, the higher critical electrical field makes it very attractive for power semiconductor devices, with outstanding specific on-resistance and smaller capacitances compared to silicon switches, which makes GaN HEMTs (high electron mobility transistors) ideal for high-speed switching.
The enhancement mode concept offers fast turn-on and turn-off speed as well as a better path towards integration, either on a chip or package level. Infineon Technologies’ CoolGaN 600 V e-mode GaN HEMTs exploit this technology according to a specific, GaN-tailored qualification process that makes it one of the most rugged and reliable solutions in the market.
The transistors enable simpler half-bridge topologies, and are applicable to applications such as server switch-mode power supplies (SMPS), telecoms, adaptors and chargers, wireless charging and Class D audio.
