Plessey fabs GaN-on-Si lighting LEDs in the UK

Plessey is sampling 350mW lighting LEDs, made in its 6in Plymouth fab using a GaN-on-silicon process.


The firm as branded is process Magic: Manufactured on GaN I/C.

“The Magic GaN line using standard semiconductor manufacturing processing provides yield entitlements of greater than 95% and fast processing times,” claimed the firm.

“PLB010350 is our first, high current device operating at anywhere from 350mA through to 2A in pulse applications,” said Plessey’s COO Barry Dennington. “We have also been able to demonstrate the versatility and the potential of the Plessey GaN on Si technology by constructing an LED with a relatively large die area.”

The data sheet is not yet up on the Plessey website.

Applications are foreseen in: accent lighting, wall washing, wall grazing and strip-lighting.
