GaN Systems Claims World’s Smallest 650V GaN Transistor

GaN Systems claims to have the world’s smallest 650V, 15A gallium nitride transistor. Measuring just 5.0 x 6.5mm, the GS66504B, one of a family of 650V devices spanning 7A to 200A, is 50% smaller than competing devices, according to the company.

Jim Witham, CEO of GaN Systems commented, “We were somewhat surprised to see announcements at last week’s PCIM power electronics exhibition and conference that trumpeted gallium nitride 600V, 15A devices in 8x8mm dual-flat no-lead (DFN) packaging as the ‘industry’s smallest’ enhancement mode devices – our part is clearly much smaller. But I suppose this is just an indication of how quickly the GaN market is moving, and a positive indication that silicon has reached its limits.”

He continued, “Our message to designers in applications as diverse as flat screen TVs, games consoles, washing machines, inverters, electric vehicles, motors and wider is the same: if you are not on-board with GaN, you will be left behind by your competitors.”

The company claims that its GaN transistors offer a 40-fold improvement in switching and conduction performance over traditional silicon MOSFETs and IGBTs. GaN Systems attributes this performance improvement to the GaN transistors’ Island Technology® die design, combined with their extremely low inductance and thermally efficient GaNPX™ packaging and Drive Assist technology. Devices are available now through its worldwide distribution network.
