HiRel - Coin GaN Driver Pair 600px.pngRuggedized, High Reliability Isolated Gate Drivers for 650V GaN Power HEMTs

The TDGD271 and TDGD274  isolators are ideal for driving GaN power parts used in a wide variety of power supply and motor control applications. The TDGD27x isolated gate drivers utilize silicon isolation technology, supporting up to 2.5 kVRMS. This technology enables industry leading common-mode transient immunity (CMTI), tight timing specifications, reduced variation with temperature and age, better part-to-part matching, and extremely high reliability.

Family of 650 V GaN HEMTs Expands with 15 A and 30 A Versions – Two new ruggedized, high power GaN HEMTs, TDG650E30BEP and TDG650E15BEP, were recently announced to augment our expanding GaN Power line. The HEMTs (High Electron Mobility Transistor) deliver lower current performance of 30- and 15-amp respectively, while the original 650V introduced last year, the TDG650E60, delivers 60 A. Both are in smaller packages allowing for higher circuit packing density. The 650 V family is the highest voltage GaN power device suite today for high-rel military, avionics, and space applications, particularly power supply, motor control, half bridge topologies, and solar and wind power.
