GaN FETs serve as drop-in SiC replacements
Transphorm announced two SuperGaN FETS in 4-lead TO-247 packages, offering an original design option or alternative to 4-lead silicon or SiC devices. The TP65H035G4YS and TP65H050G4YS are both 650-V FETs with an on-resistance of 35 mΩ and 50-mΩ, respectively. Based on the company’s GaN-on-silicon substrate process, the devices are well-suited for high-volume manufacturing on silicon production lines.
The two SuperGaN FETs support power supplies at 1 kW and higher in such applications as data centers, renewables, and industrial equipment. Their 4-lead configuration provides a Kelvin source terminal to enhance switching efficiency. In a hard-switched synchronous boost converter, the 35-mΩ 4-lead FET reduced losses by 15% at 50 kHz and 27% at 100 kHz compared to a SiC MOSFET with comparable on-resistance.
The TO-247-4L devices offer the following core specifications:
The 50-mΩ TP65H050G4YS is available now. The 35-mΩ TP65H035G4YS is sampling and slated for release in Q1 2024.

LED backlight driver offers dual LCD bias
Kinetic Technologies’ KTZ8868 integrates in a single chip an 8-LED backlight driver and 250-mA LCD bias power for up to 12-in. display panels. High switching frequency allows the use of a smaller inductor and capacitor, while an input operating range of 2.7 V to 5.5 V accommodates 1-cell lithium-ion batteries or a 5-V supply.
The LED driver has two step-up converters, and each converter drives four current sinks. Each of the eight current sinks can regulate up to 30 mA. Maximum boost output voltage is 40 V. The LCD bias power section comprises a step-up converter, LDO regulator, and an inverting charge pump to generate dual outputs, whose voltage is programmable via an I2C interface.
Built-in protection features of the KTZ8868 include inductor current limit, output short circuit, output overvoltage, LED fault (open or short), and thermal shutdown. The part is housed in a 5×5-mm, 32-lead WQFN package.

Digital POT Resistor with Display
Hello, I bought a digital POT resistor to replace the one installed in my GameCube console. I plan to mount this underneath or on the side of the console to easily adjust it as some reproduction games work at different settings. I want to attach a display to the resistor to display what the ohms are currently at and am wondering if there is an easy way to do this. I searched online, only found components to display voltage. Appreciate the help!

ZINSIGHT enhances efficiency in new energy vehicle e-compressor controller with STMicroelectronics’ silicon-carbide
Extends electric vehicle mileage in summer and winter, reduces total ownership cost
STMicroelectronics, a global semiconductor leader serving customers across the spectrum of electronics applications, has announced it is supplying its third-generation silicon-carbide (SiC) MOSFET technology for the e-compressor controllers from ZINSIGHT Technology, a Chinese high-tech company focusing on SiC power modules and advanced electric power conversion systems, for new energy vehicles (NEVs). These highly efficient controllers offer several benefits including an extended electric vehicle (EV) driving range of 5~10km (for a medium-size EV model with battery capacity from 60 kWh to 90 kWh) that is particularly beneficial during the summer and winter seasons.
ZINSIGHT is the only company in the world today that mass-produces SiC-based e-compressor controllers for air-conditioning running on 400V, 800V and 1000V EV platforms, delivering a significant number of units by the end of 2023. ST’s advanced third-generation 1200V SiC MOSFET ensures industry-leading process stability and performance, efficiency, and reliability. The EV e-compressor controllers use ST’s third-generation SiC MOSFET technology in combination with ZINSIGHT’s unique cooling solution and advanced thermal protection design. Together the e-compressor controllers deliver better thermal management for NEVs, improved NVH (noise, vibration, and harshness), and greater compactness and cost efficiency for e-compressors. For example, without compromising summer and winter mileage, this solution can help carmakers achieve significant cost saving per EV in overall system expenses.
“ZINSIGHT and ST share the goal of sustainability through technology innovations. Leveraging ST’s leadership in SiC technology and ZINSIGHT’s innovative design and state-of -the-art process, our cooperation with ST is accelerating innovation in e-compressor controller design, achieving breakthroughs in performance, efficiency, and mileage,” said Doctor Jingkui SHI, President of ZINSIGHT. “ST and ZINSIGHT continue to expand our cooperation, contributing to the innovation and development of China’s NEV industry.”
As a pioneer in SiC technology, ST is advancing SiC manufacturing process using a complete vertically integrated supply chain. ST continues to gain design wins from a wide range of leading automotive and industrial leaders for its well-recognized product reliability. At the same time, ST is continuing to invest in expanding production capacity and enhancing manufacturing technology.
“Developing and refining SiC technology for more than 25 years, ST has built a big portfolio of key patents,” said Henry CAO, Executive Vice President of Sales & Marketing, China Region, STMicroelectronics. “ST’s SiC technology has been widely adopted in onboard chargers, traction inverters, and DC-DC converters for NEVs.
