Wide-bandgap technologies (SiC and GaN) from Infineon enable the most efficient systems possible to power the green and digital transformation

The path to a more energy-efficient world is heavily reliant on the adoption of wide-bandgap (WBG) semiconductors. These innovative materials offer a multitude of benefits, including enhanced power efficiency, reduced size, lower weight, and decreased overall cost.

As a pioneer in the field of power semiconductors, Infineon boasts an impressive heritage spanning over two decades in Silicon Carbide (SiC) and Gallium Nitride (GaN) technologies. Our profound system expertise, coupled with our in-house manufacturing capabilities, makes us an ideal partner for companies seeking to harness the potential of WBG power electronics.

Wide-Bandgap Semiconductor Benefits

Depending on application requirements, silicon carbide (CoolSiC?) and gallium nitride (CoolGaN?) have specific value propositions enabling highest levels of system performance. They leverage the full potential based on the power ratings and switching frequency required by the application.

The higher efficiency and durability of WBG semiconductors contribute to reduced energy consumption and lower greenhouse gas emissions. Additionally, the reduced need for cooling and smaller system sizes can lead to substantial cost savings in both manufacturing and operation. These environmental and economic benefits make WBG semiconductors attractive for sustainable technology development.

The robust nature of WBG materials leads to longer-lasting devices that are less prone to wear and degradation over time. This durability is essential in critical applications where reliability is paramount, such as in military and medical devices. The extended lifespan also contributes to lower maintenance costs and improved overall system reliability.

WBG devices can handle higher power densities, which allows for the creation of smaller and lighter electronic components. This is particularly beneficial in portable and space-constrained applications, such as aerospace and consumer electronics. High power density also means that more power can be delivered in a smaller package, enhancing the performance of power systems.

WBG materials have greater energy efficiency. They can operate at higher voltages, frequencies, and temperatures with less energy loss compared to silicon. This efficiency is particularly advantageous in power electronics, where reducing energy loss translates directly to cost savings and improved performance in applications such as power supplies, inverters, and motor drives.

WBG semiconductors can function at much higher temperatures than silicon. This is crucial in applications where high heat generation is unavoidable, such as in electric vehicles (EVs) and industrial machinery. The ability to operate at elevated temperatures reduces the need for complex cooling systems, thereby simplifying design and lowering costs.

These materials can switch on and off faster than silicon-based devices. This higher switching frequency enables more compact and lightweight designs for power converters and other electronic systems. It also improves the overall performance and reliability of these systems, making them more suitable for advanced technologies like 5G communications and high-frequency radar systems.
