Transphorm Releases First JEDEC-Qualified 600V GaN-on-Silicon Power Devices

Transphorm Inc. today announced the Total GaN™ family of GaN (Gallium Nitride) on silicon transistors and diodes, establishing the world’s first JEDEC-qualified 600 V GaN device platform. This marks a significant milestone in the broad adoption of GaN-based power electronics in power supplies and adapters, PV inverters for solar panels, motor drives, as well as power conversion for electric vehicles. Based on Transphorm’s patented, high-performance EZ-GaN™ technology, the TPH3006PS GaN high electron mobility transistor (HEMT) combines low switching and conduction losses to reduce energy loss by 50 percent compared to conventional silicon-based power conversion designs.

The TO-220-packaged GaN transistor features low on-state resistance (RDS(on)) of 150 milliohms (mΩ), low reverse-recovery charge (Qrr) of 54 nanocoulombs (nC) and high-frequency switching capability — all of which result in more compact, lower cost systems. Also available in industry-standard TO-220 packages, the TPS3410PK and TPS3411PK GaN diodes offer 6-A and 4-A operating currents, respectively, with a forward voltage (Vf) of 1.3 Volts. In addition, three application kits — PFC (TDPS400E1A7), Daughter Board (TDPS500E0A) and Motor Drive (TDMC4000E0I) — are available for rapidly benchmarking the in-circuit performance of Transphorm’s products.

“Solidifying its leadership position in high-voltage GaN power conversion solutions, Transphorm has accomplished the first qualification of 600V GaN devices on silicon substrates,” said Primit Parikh, President of Transphorm. “This is critically important because it allows manufacturers to access the energy savings from our GaN transistor and diode products with the cost benefits of silicon. The introduction of the Total GaN family dispels the myth that qualification of high-voltage GaN on silicon is not possible, and enables the introduction of new power products in the marketplace that are dramatically more efficient compared to silicon-based products. Transphorm is today driving the next power standard.”

For approved customers, the TPH3006PS HEMT device is available for sale at a price of $5.89 each in 1,000 quantities. The TPS3410PK and TPS3411PK diodes are priced at $2.06 and $1.38, respectively, also in 1,000-piece quantities.
