Power MOSFET

Infineon is the market leader in efficient solutions for power generation, power supply, and power consumption, offering an extensive portfolio of state-of-the-art power MOSFETs. The latest generation of high power MOSFETs have been designed to deliver best-in-class performance, to improve efficiency, and to optimize thermal performance and EMI behavior. As the world’s leading MOSFET manufacturer and supplier, Infineon offers superior quality metal-oxide-silicon transistors to suit a variety of needs. Throughout our product portfolio, you’ll find reliable solutions to all major challenges faced by designers and manufacturers across a range of applications.

For AC-DC applications requiring high-voltage blocking capability and fast switching with low losses, the revolutionary CoolMOS™ superjunction technology ensures more efficient power supplies. Infineon’s superjunction MOSFETs serve both current and future trends in different topologies, ranging from a simple flyback to TCM Totem Pole PFC. Designers benefit from high temperature capability, improved form factor, and increased efficiency.

DC-DC applications can be characterized by their need for extremely fast switching with low losses, or more robust switching at moderate frequencies. Infineon’s unique OptiMOS™ power MOSFET technology ensures ultra-low switching losses in power supply applications above 100kHz, affording designers high efficiency and new possibilities in hard-switching applications. The OptiMOS™ product range encompasses a broad portfolio of low-voltage MOSFETs, enabling system designers to increase power density and reduce cost while maintaining the highest level of reliability.

In applications requiring high avalanche protection, such as motor control, developers benefit from the highly robust StrongIRFET™ power MOSFET. These MOSFETs ensure maximum efficiency in end applications that demand a high level of energy efficiency but are restricted in terms of space—such as power and gardening tools, light electric vehicles, drones, and e-bikes. Infineon’s innovative MOSFET transistors deliver excellent performance while reducing costs, making them the optimum choice for performance-driven DC-DC converters.

For designs requiring the highest quality and enhanced protection features, Infineon’s automotive qualified n-channel and p-channel MOSFETs offer the ideal solution. These high power MOSFETs exceed AEC-Q101 industry standards, making them the most reliable MOSFETs available on the market to date.

Infineon’s complete range of n-channel and p-channel power MOSFETs and systems enable innovation, performance, and efficiency for your desired application—from switch mode power supplies (SMPS) to computing, motor control and drives, consumer, mobile devices, lighting solutions, automotive, and more.
