Transphorm, Inc. introduced three SuperGaN® FETs in TOLL packages with on-resistances of 35, 50, and 72 milliohms. Transphorm’s TOLL package configuration is industry standard, meaning the SuperGaN TOLL FETs can be used as drop-in replacements for any e-mode TOLL solution.
The new devices also offer Transphorm’s proven high voltage dynamic (switching) on-resistance reliability that is generally lacking in leading foundry-based e-mode GaN offerings. To sample the devices, visit Transphorm’s product page: https://www.transphormusa.com/en/products/.
The three surface mount devices (SMDs) support higher power applications operating within an average range of 1 to 3 kilowatts. These power systems are typically found in high performance segments such as computing (AI, server, telecom, data center), energy and industrial (PV inverters, servo motors), and other broad industrial markets which, collectively, have a current global GaN TAM of $2.5B. Notably, the FETs are optimal solutions for today’s rapidly expanding AI systems that rely on GPUs requiring 10 to 15 times the power of traditional CPUs.
Transphorm’s high power GaN devices are already widely supplied to leading customers who use them to power in-production high performance systems including datacenter power supplies, high power gaming PSUs, UPSes, and microinverters. These applications can also be supported by the TOLL devices as can electric-vehicle-based DC-to-DC converters and onboard chargers, with the underlying SuperGaN die already automotive (AEC-Q101) qualified.
The SuperGaN TOLL FETs represent the sixth package type offered by Transphorm, giving customers the widest selection of packages to meet their unique design requirements. As with all Transphorm products, the TOLL devices harness the inherent performance and reliability advantages made possible by the normally-off d-mode SuperGaN platform.
For a detailed competitive analysis between SuperGaN and e-mode GaN, download the company’s latest white paper titled The Fundamental Advantages of d-Mode GaN in Cascode Configuration. The white paper’s conclusion aligns with a head-to-head comparison released earlier this year showing the 72 milliohm SuperGaN FETs outperforming larger 50 milliohm e-mode devices in a commercially available 280 W gaming laptop charger.
SuperGaN devices lead the market with unmatched:
- Reliability at < 0.03 FIT
- Gate safety margin at ± 20 V
- Noise immunity at 4 V
- Temperature coefficient of resistance (TCR) at 20% lower than e-mode
- Drive flexibility with standard drivers and protection circuits readily available in silicon-based controllers/drivers
Device Specifications
The robust 650 V SuperGaN TOLL devices are JEDEC qualified. Because the normally-off d-mode platform pairs the GaN HEMT with a low voltage silicon MOSFET, the SuperGaN FETs are easy to drive with commonly used off-the-shelf gate drivers. They can be used in various hard- and soft-switching AC-to-DC, DC-to-DC, and DC-to-AC topologies to increase power density while reducing system size, weight, and overall cost.Part Dimensions (mm) RDS(on) (mΩ) typ RDS(on) (mΩ) max Vth (V) typ Id (25°C) (A) max TP65H035G4QS 10 x 12 35 41 4 46.5 TP65H050G4QS 10 x 12 50 60 4 34 TP65H070G4QS 10 x 12 72 85 4 29 Original – Transphorm

Researchers at the Indian Institute of Science (IISc) have developed a fully indigenous gallium nitride (GaN) power switch that can have potential applications in systems like power converters for electric vehicles and laptops, as well as in wireless communications. The entire process of building the switch – from material growth to device fabrication to packaging – was developed in-house at the Centre for Nano Science and Engineering (CeNSE), IISc.
Due to their high performance and efficiency, GaN transistors are poised to replace traditional silicon-based transistors as the building blocks in many electronic devices, such as ultrafast chargers for electric vehicles, phones and laptops, as well as space and military applications such as radar.
“It is a very promising and disruptive technology,” says Digbijoy Nath, Associate Professor at CeNSE and corresponding author of the study published in Microelectronic Engineering. “But the material and devices are heavily import-restricted … We don’t have gallium nitride wafer production capability at commercial scale in India yet.” The know-how of manufacturing these devices is also a heavily-guarded secret with few studies published on the details of the processes involved, he adds.
Power switches are used to control the flow of power to – essentially turn on or off – electronic devices. To design the GaN power switch, the IISc team used a metal organic chemical vapour deposition technique developed and optimised over a decade by researchers in the lab of Srinivasan Raghavan, Professor and Chair, CeNSE. It involves growing GaN alloy crystals layer by layer on a two-inch silicon wafer to fabricate a multi-layered transistor.
The entire process needs to be carried out carefully in a clean room to ensure that no defects arise due to environmental conditions like humidity or temperature, which can affect device performance. The team also took the help of Kaushik Basu, Associate Professor in the Department of Electrical Engineering (EE), and his lab, to build an electrical circuit using these transistors and test their switching performance.
GaN transistors typically operate in what is called a “depletion mode” – they are on all the time unless a negative voltage is applied to turn them off. But power switches used in chargers and adapters need to work the other way around – they normally need to be off and not carrying current, and should only turn on when a positive voltage is applied (“enhancement mode”). To achieve this operation, the team combined the GaN transistor with a commercially available silicon transistor to keep the device normally off.
“The packaging of the device was also indigenously developed,” explains Rijo Baby, PhD student at CeNSE and first author of the study. After packaging and testing, the team found the device performance to be comparable to state-of-the-art switches available commercially, with a switching time of about 50 nanoseconds between on and off operations.
Going forward, the researchers plan on scaling up the device dimensions so that it can operate at high currents. They also plan to design a power converter that can step up or step down voltages.
“If you look at strategic organisations in India, they have a hard time procuring GaN transistors … It is impossible to import them beyond a certain quantity or power/frequency rating,” says Nath. “This is essentially a demonstration of indigenous GaN technology development.”
