Gallium nitride (GaN) power devices

Maximize power density and reliability with our portfolio of GaN power devices for every power level

Our family of gallium nitride (GaN) FETs with integrated gate drivers and GaN power devices offer the most efficient GaN solution with lifetime reliability and cost advantages. GaN transistors can switch much faster than silicon MOSFETs which offers the potential to achieve lower switching losses. Our GaN transistors are being adopted for a wide range of applications from telecommunications, servers, motor drives, laptop adapters and on-board chargers for electric vehicles.


What is GaN?

Learn more about about Gallium Nitride and its benefits for power converter systems, including lower switching losses and higher frequency operation. 


Twice the speed, half the losses

GaN with an integrated driver enables switching speeds of >150 V/ns, resulting in half the losses compared to discrete GaN FETs. This, combined with our low-inductance package, delivers clean switching and minimal ringing in every power application.


Lifetime reliability

TI GaN-on-silicon process utilizes our 100% internal manufacturing facilities for fabrication, assembly and test, thus leveraging internally-owned capacity and maximized product quality.

GaN FETs with integrated driver & protection for power density

GaN FETs have inherently superior performance over traditional silicon FETs, which is enabling engineers to push the boundary in power designs and reach new levels of power density and efficiency. From consumer applications such as AC/DC power supplies all the way up to multi-kW, three-phase converters – GaN is reducing the weight, size and cost of these power designs while also reducing energy consumption. GaN’s high-speed switching is changing the way power systems look today, enabling market trends such as ultra-thin power supplies, motor drive integrated robotics and achieving >200% more power density in next-generation datacenters and 5G rectifiers.
