EL SEGUNDO, Calif.— June 2021 — EPC announces the introduction of a new family of radiation-hardened gallium nitride transistors and integrated circuits. With higher breakdown strength, faster switching speed, higher thermal conductivity and lower on-resistance, power devices based on GaN significantly outperform silicon-based devices. The lower resistance and gate charge enable faster power supply switching frequencies resulting in higher power densities, higher efficiencies, and more compact and lighter weight circuitry for critical spaceborne missions. Gallium nitride is also inherently radiation tolerant, making GaN-based devices a reliable, higher performing power transistor option for space applications.

Efficient Power Conversion (EPC) will showcase the company’s latest enhancement-mode gallium nitride-based FETs and ICs demonstrating how GaN technology’s superior performance is transforming power delivery for high power density computing, automotive, eMobility, and robotics.

EL SEGUNDO, Calif.— June 2021 — The EPC team will be delivering multiple technical presentations, an educational tutorial, and an exhibitor webinar on gallium nitride (GaN) technology and applications at the upcoming Applied Power Electronics Conference (APEC) Virtual Conference + Exposition, June 14-17. In addition, the company will participate in the event’s virtual exhibition, showing its latest eGaN^® FETs and ICs in customers’ end products that are rapidly adopting eGaN technology.

GaN transistors and ICs increase power density in motor drive applications. An optimal lay-out approach allows obtaining ring-free output switching waveforms and clean current reconstruction signals either from leg shunts or from in-phase shunts.

Efficient Power Conversion (EPC) expands AEC Q101 product family with the addition of the EPC2219, 65 V gallium nitride transistor with integrated reverse gate clamp diode optimized for high resolution lidar systems.

EL SEGUNDO, Calif.— March 2021 — EPC announces successful AEC Q101 qualification of the 65 V EPC2219 designed for lidar systems in the automotive industry and other harsh environments. 

Enhancement-mode gallium nitride (eGaN) FETs have demonstrated excellent thermomechanical reliability in actual operation in the field or when tested according to AEC or JEDEC standards. This is because of the inherent simplicity of the “package,” the lack of wire bonds, dissimilar materials, or mold compound. Recently, an extensive study of underfill products was conducted to experimentally generate lifetime predictions. A finite element analysis at the end of this section explains the experimental results and generates guidelines for selection of underfill based on key material properties.
