The firm also said that its wafer-foundry’s 15 million parts annual capacity for 50mΩ devices could “easily” scale to 5x that volume, and that its manufacturing process can be structured to scale from 6in wafers now to 8in wafers.

Transphorm’s in-production customers, it said, include Corsair (PC gaming PSUs), Bel Power, Delta (server PSUs), Yaskawa (servo drives), Inergy, Telcodium (portable power).

“While we are very pleased with what Transphorm has achieved in partnership with our customers, we are even more excited to see high voltage power semiconductor leaders like Nexperia and Infineon join the GaN revolution,” said Transphorm CEO Mario Rivas. “The pivotal benchmarks of any new technology’s market acceptance are adoption by leading customers in key market segments and the emergence of multiple, strong suppliers capable of supporting ensuing high volume ramps.”

Nexperia’s plans to release 600V+ GaN transistors and Infineon has a 600V portfolio.

“2018 has been a game-changing year for high voltage GaN,” said company founder Primit Parikh. “More than 250,000 650V GaN FETs from Transphorm are deployed in our customers’ power converter and inverter products. With our production volumes to date, we’re able to estimate more than 1.3 billion field hours of operation with a field FIT rate in the low single digits as well as over a billion hours of mean time before failure.”

Transphorm’s GaN transistor offering includes JEDEC and AEC-Q101 qualified parts.
