Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) is the first company worldwide manufacturing automotive power MOSFETs on 300-millimeter thin wafers. The first product family OptiMOS™ 5 40V is optimized for CO2 reduction applications. The products are manufactured at Infineon’s fab in Villach, Austria.

“With the automotive power MOSFETs in 300-millimeter thin-wafer technology Infineon strengthens its technology and market leadership,“ says Jochen Hanebeck, President of the Automotive Division at Infineon Technologies AG. “Infineon ensures to offer high-performance automotive power MOSFETs in large scale volume production at competitive price. Our automotive customers will benefit from supply security and our long-term productivity roadmap of the 300-millimeter production line.”

Infineon’s leading 300-millimeter thin-wafer technology is a key basis for performance improvements of next-generation automotive power MOSFET product families. Thin-wafer technology minimizes power losses and enables compact MOSFET designs for high system efficiency and power density. With wafer thinning down to 60µm (0.06mm) OptiMOS 5 power semiconductors on 300-millimeter thin-wafer technology are among the world’s thinnest. For comparison: A sheet of standard writing paper features about 110µm (0.11mm).

Thanks to the 50 percent larger wafer diameter compared to standard 200-millimeter wafers, two-and-a-half times as many chips can be produced on each 300-millimeter wafer.

Performance leading OptiMOS 5 40V automotive power MOSFETs

Infineon starts its OptiMOS 5 thin-wafer product portfolio with 40V variants in a S308 package (TSDSON-8) with a small footprint dimension of only 3.3 x 3.3mm.

Compared to the previous OptiMOS generation, the OptiMOS 5 40V products feature a 40 percent reduction in on-resistance RDS(on) and further minimize power losses. In addition, they offer a 35 percent lower Figure of Merit RDS(on)xQg to further optimize switching behavior. As a result, the OptiMOS 5 40V products deliver high power density and energy efficiency for a broad range of automotive BLDC and H-bridge drive applications such as power window, door control, sun roof, fuel pumps, and also valve control and fast switching DC/DC converters.


OptiMOS 5 40V products are available in S308 package (TSDSON-8) with RDS(on) ranging from 2.8mOhm to 8.4mOhm. The OptiMOS 5 40V S3O8 products are available in high volume.
