600V GaN transistor is 'industry's first' in TO-247 package

600V GaN transistor is 'industry's first' in TO-247 package
From APEC 2015, Transphorm has announced that it is now offering engineering samples of its TPH3205WS transistor, the first 600V GaN transistor in an TO-247 package. Offering resistance of 63 mΩ and 34A ratings, the device utilises the company’s Quiet Tab source-tab connection design, which reduces EMI at high dv/dt to enable low switching loss and high-speed operation in power supply and inverter applications.
