Infineon Technologies broadened its CoolGaN series with two new devices: the CoolGaN 400 V and the CoolGaN 600 V. Gallium nitride (GaN) offers fundamental advantages over silicon, with outstanding specific dynamic on-state resistance and smaller capacitances compared to silicon MOSFETs. The new CoolGaN 400 V device will appeal to audio product designers looking for a premium solution for home or professional Class D amplifiers.
