STMicroelectronics SGT G-HEMT™ E-Mode PowerGaN Transistors
STMicroelectronics SGT G-HEMT™ E-Mode PowerGaN Transistors are high‑performance, enhancement‑mode (normally‑off) GaN devices designed to deliver exceptionally fast switching, low conduction losses, and high power density across demanding power‑conversion applications. These transistors leverage Gallium Nitride’s wide‑bandgap advantages to achieve extremely low capacitances, minimal gate charge, and zero reverse‑recovery charge, enabling superior efficiency compared to traditional silicon power switches.
The STMicroelectronics SGT transistors combine advanced G‑HEMT structures with robust packaging technologies to support high current capability and ultra‑fast switching behavior, promoting improved thermal performance and compact system designs. Key features include Kelvin‑source pads for optimized gate driving, high power‑management capability, and strong ESD robustness, making these transistors well‑suited for AC‑DC and DC‑DC converters, solar inverters, industrial power supplies, and other high‑frequency, high‑efficiency systems. Overall, ST’s E‑Mode PowerGaN portfolio provides designers with a powerful platform for building next‑generation power electronics with higher efficiency, reduced size, and enhanced performance.
