World's smallest 650V, 15A gallium nitride power transistors are 50% smaller
GaN Systems has unveiled what it believes to be the world's smallest 650V,
15A gallium nitride transistor. With a footprint of just 5mm x 6.5mm, the
GS66504B - one of a family of 650V devices that spans 7A to 200A - is 50%
smaller than competing devices.
Commenting, Jim Witham, CEO GaN Systems, said: "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."
"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."
GaN Systems believes it is the first company to have developed and brought a
comprehensive product range of devices with current ratings from 7A to 250A
to the global market - its Island Technology(r) die design, combined with
its extremely low inductance and thermally efficient GaNPX(tm) packaging and
Drive Assist technology means the company's GaN transistors offer a 40-fold
improvement in switching and conduction performance over traditional silicon
MOSFETs and IGBTs, says the company.
