Cloud and Computing Power Solutions

Modern AI platforms, cloud data centers, enterprise servers, and high-performance computing systems require scalable, energy-efficient power architectures to support increasingly demanding processors, accelerators, GPUs, and memory subsystems. Reliable power delivery is essential for maximizing system performance, improving energy efficiency, and reducing operational costs.
onsemi delivers advanced power semiconductor solutions for computing infrastructure, including AC-DC power conversion, DC-DC regulation, point-of-load (PoL) power delivery, hot-swap protection, and intelligent power management. Leveraging innovative Silicon Carbide (SiC), Gallium Nitride (GaN), MOSFET, and mixed-signal technologies, onsemi helps designers achieve higher power density, improved efficiency, and greater system reliability across AI servers, cloud computing platforms, data centers, edge computing systems, and enterprise IT infrastructure.
With deep expertise in power conversion and computing architectures, onsemi enables next-generation computing systems that support the growing demands of artificial intelligence, machine learning, hyperscale data centers, and high-performance processing applications.

Silicon Carbide (SiC) MOSFETs

Our SiC MOSFETs are designed to be fast and rugged and include system benefits from high efficiency to reduced system size and cost. MOSFETs are metal–oxide–semiconductor field-effect transistors with insulated gates. These silicon carbide MOSFETs have a higher blocking voltage and higher thermal conductivity than silicon MOSFETs, despite having similar design elements. SiC power devices also have a lower state resistance and 10 times the breakdown strength of regular silicon. In general, Systems with SiC MOSFETs have better performance and increased efficiency when compared to MOSFETs made with silicon material.

There are many advantages to choosing SiC MOSFETs over silicon MOSFETs, such as higher switching frequencies. High-temperature development is also not a concern when using SiC MOSFET modules because these devices can operate efficiently even in high heat. Additionally, with SiC MOSFETs, you benefit from a more compact product size because all components (inductors, filters, etc.) are smaller.
