Transform Releases Industry’s First Simulation Model for 1200V GaN-on Apphire Devices
2023-06-12
The device is ready for the application of the innovative normally closed GaN platform of Transporm in the new generation of automobiles and three-phase power systems

Transform, Inc. (Nasdaq: TGAN), a leading enterprise and global supplier of highly reliable and high-performance gallium nitride (GaN) power conversion products, announced the launch of its 1200V power transistor simulation model and initial specifications. TP120H070WS power transistor is the only 1200V GaN-on Apphire power semiconductor launched so far, leading similar products. The launch of this product shows that Transporm has the ability to support future automotive power systems, as well as three-phase power systems that have been widely used in the industrial, data communication and renewable energy markets. Compared to alternative technologies, these applications can benefit from higher power density and superior reliability of 1200V gallium nitride devices, equivalent or superior performance, and more reasonable costs. Transform has recently verified the higher performance of gallium nitride devices in 5kW 900V buck converters with a switching frequency of 100kHz. The 1200V gallium nitride device achieved an efficiency of 98.7%, surpassing mass-produced SiC MOSFETs with similar ratings.


The innovative 1200V technology also demonstrates Transform's leading position in gallium nitride power conversion. The Vertical integration mode, its own epitaxial wafer production capacity, and patented process technology, combined with decades of engineering expertise, enable the company to bring the best performance GaN device combination to the market, and also has significant differentiation advantages in the following four aspects: manufacturability, easy drive, easy design, and reliability.

At the PCIM 2023 exhibition from May 9th to 11th, Transform also released information about 1200V devices.

Preliminary device specifications and how to obtain samples

The 1200V technology of Transform is based on proven processes and mature technology, meeting customers' reliability requirements. The GaN on Sapphire process is currently mass-produced in the LED market. In addition, the 1200V technology fully utilizes the high-performance, normally closed gallium nitride platform used in the current device combination of Transform.

The main specifications of TP120H070WS device include:

Internal resistance value 70 milliohms

Normally closed type

Efficient bidirectional conduction

Maximum ± 20V gate voltage

4-volt gate drive low disturbance

Zero QRR reverse recovery charge

3-pin TO-247 package



We suggest combining the Verilog-A device model with the SIMetrix Pro v8.5 circuit simulator. The LTSpice model is currently under development and will be released in the fourth quarter of 2023. Simulation modeling helps to achieve rapid and efficient power system design verification, while also reducing design iterations, development time, and hardware investment.

The 1200 volt power transistor sample is expected to be launched in the first quarter of 2024.

Application of Transform Gallium Nitride Power Devices in Automotive Power Systems and Charging Ecosystems

1200V gallium nitride devices are not only an ideal solution for various market applications, but also provide unique advantages for automotive systems.

The electric vehicle industry, especially at the higher kilowatt nodes of large vehicles, will develop towards 800V batteries in the second half of this decade. Therefore, the 1200 volt power conversion switch will be used to provide the required performance level. Therefore, Transpharm's 1200 volt platform will definitely play a major role in the field of new generation vehicle charger, DC-DC converter, drive inverter and Charging station system.

For electric vehicles currently using 400V batteries, the Transformer can provide a 650V normally closed SuperGaN ® Power tube solution. These power devices comply with the AEC-Q101 standard and can withstand high temperatures of 175 ° C, and have been mass-produced.
