Transform, a world leader in GaN power semiconductors, has announced the launch of a four-terminal TO-247 package (TO-247 -4L) has launched a new SuperGaN® device. The TP65H035G4YS FET and TP65H050G4YS FET have on-resistances of 35mΩ and 50mΩ, respectively, and provide versatile switching functionality while reducing energy loss with a Kelvin source terminal. The new device is fabricated on Transform’s established GaN-on-Silicon substrate fabrication process, which is cost-effective, reliable, and suitable for high-volume production on silicon manufacturing lines. The 50mΩ TP65H050G4YS FET is available now, and the 35mΩ TP65H035G4YS FET is currently available for sampling and is expected to be available in Q1 2024.
Transform’s 4-terminal SuperGaN® devices can be used in unique design-ins or as drop-in replacements for 4-terminal silicon and SiC solutions for power supplies above 1 kilowatt in a wide variety of applications, including data centers, renewable energy, and industrial applications. It can be used for. The 4-terminal structure gives the user more freedom to improve switching performance. A 35 mΩ SuperGaN 4-terminal FET reduces losses by 15 percent at 50 kHz and 27 percent at 100 kHz in a hard-switching synchronous boost converter compared to a SiC MOSFET device with comparable on-resistance.

Transform’s SuperGaN FETs have unique strengths, including:
- Industry-leading durability (gate threshold +/-20V, noise immunity 4V)
- Reduces circuits around the device and allows for easy design
- Driving FETs is easy because common off-the-shelf drivers can be combined with silicon devices.
The TO-247-4L device offers the same durability, design and driveability with the following core specifications:
