Power MOSFET

A well-considered selection of the MOSFET defines the overall performance. Due to its simplicity and robustness, Infineon’s game-changing technology is the best choice as it enables improved form factors and contributes to an overall system cost reduction. Another positive side effect is the overall reduced energy consumption. This helps to minimize CO₂ emissions and therefore reduces cost and is beneficial for the end-consumer as well. Infineon’s CoolMOS™ superjunction MOSFET offers extensive options for consumer, industrial and automotive applications such as lighting, TV, audio, server/telecom, solar, EV charging, DC-DC converter, onboard chargers and many more.

DC-DC applications can be classified by their need for extremely fast switching with low losses or more robust switching at moderate frequencies.

Designers benefit from the ultra-low switching losses of the Infineon OptiMOS™ power MOSFET technology in power supply applications above 100kHz. Infineon’s OptiMOS™ low-voltage MOSFET offers high efficiency and new possibilities in hard switching applications. It helps system designers to increase power density and reduce cost with the highest level of reliability.

In applications with the need for high avalanche protection such as motor control, developers benefit from the highly robust StrongIRFET™ power MOSFET. The MOSFETs can bring the highest energy efficiency to end applications like power and gardening tools, light electric vehicles, drones, and e-bikes that demand a high level of energy efficiency but are restricted in available space.
Infineon’s highly innovative MOSFET transistors deliver excellent performance and additionally reduce costs. These devices are the best choice for performance driven DC-DC converters.

Designs requiring the highest quality and enhanced protection features benefit from Infineon's automotive qualified n-channel and p-channel MOSFETs which go beyond AEC-Q101 industry standards providing the most reliable MOSFETs in the industry.
