Backed by customer commentary and published metrics, Transphorm’s high-voltage GaN FETs move power electronics beyond Silicon’s limitations.
Transphorm’s customer base includes product manufacturers unsatisfied with the status quo. Companies on the bleeding edge of innovation that strive to break their own power system performance records, raising the bar industry-wide. Gallium nitride power transistors are proving to be their disruptive technology of choice.
Inergy’s Kodiak Extreme utilizes a photovoltaic (PV) inverter and battery charger both integrating Transphorm’s JEDEC-qualified GaN platform. These power systems result in a generator that is more powerful, lighter, and quicker to charge than competitive products.
TDK-Lambda’s redesigned standard power module uses a bridgeless totem-pole power factor correction topology to optimize Transphorm’s TPH3206LDG FET in an 8×8 PQFN package.
High quality, high reliability GaN in standard TO-XXX packages.
Transphorm’s GaN FETs switch up to 4x faster than Silicon solutions. Further, unlike Si MOSFETs, the GaN transistors are inherently bi-directional and optimized in a bridgeless totem-pole power factor correction design.
Our Q+R is in large part enabled by our design choice. Today, cascode is the only configuration proven to enable GaN in real-world applications. Transphorm’s GaN is backed by extensive lifetime, quality and reliability data—unavailable with other configurations today, such as pGaN e-mode.

High-voltage GaN technology benefits numerous markets that require reliable higher efficiency, higher performance power conversion. The highest adoption rates are projected for the following application areas:
Increases clean power output in standardized server and telecom form factors.
Improved efficiencies result in lower thermals, improved power density and lower system cost.
Reduces size and weight of systems that run industrial factories, charge battery powered forklifts, electric vehicles and keep critical data accessible..
Generates longer distance per charge with a lower overall system cost.
