Can GaN Challenge Si Power Devices?

Posted October 21, 2008 8:00 AM

As a result of more than five years of device research and development gallium nitride (GaN) power devices may soon prove to be big competition for silicon (Si) power devices given their superior performance. The exotic devices are expected to target primarily AC/DC and DC/DC conversion, and class D audio applications. Will the integration of GaN power devices be the source of any design issues? Are there any remaining processing issues associated with the fabrication of such devices? What other immediate applications do you see GaN power devices serving?

I have read about them in a few trade magazines, and they look promising. Unforuneately, I have not used them myself yet, nor have I seen any being used. There may be other drawbacks to them that are not yet apparent. We'll have to wait and see, I guess.

It'll all come down to price - if GaN can be produced as cheap, then it will be a better product. But, there are better mousetraps then GaN already in the works (such as AlN) for certain applications, so the race is on.

Those devices do look promising, and should not be as toxic as the GaAs devices presently being used.

Like others here, I have yet to get my hands on one.

Kind Regards....

What planet are you from last time I looked no one was eating said toxic chips and if your talking about dumping said chips I am afraid you lost the plot, as one the chemicals are held in a crytaline structure and then most likely in some form of plastic.2) The quanitity of both materials are so low you would be amazed. 3) Dont comment on subject matter you have no idea about.. 4. Not as toxic um it is either toxic or it is not .. no such thing as "not as toxic"

Hello Guest,

You do not need to be insulting.

Manners maketh the man.

The GaAs devices have to be manufactured.

The toxicity is during the mining and refining of the two elements, plus the manufacturing afterwards.

I thought you should know, as you did not seem to understand, from your post above.

Kind Regards....
