The safe hot-swap operation in AI servers and telecom requires MOSFETs with a robust linear operating mode as well as a low R DS(on). Infineon Technologies AG addresses this challenge with the new OptiMOS™ 5 Linear FET 2, a MOSFET designed to provide the ideal trade-off between the R DS(on) of a trench MOSFET and the wide safe operating area (SOA) of a classic planar MOSFET.
The device prevents damage to the load by limiting the high inrush current and ensures minimal losses during operation due to its low R DS(on). Compared to the previous generation (the OptiMOS Linear FET), the OptiMOS Linear FET 2 offers improved SOA at elevated temperatures and reduced gate leakage current, as well as a wider range of packages. This allows for more MOSFETs to be connected in parallel per controller, reducing bill-of-material (BOM) costs and offering more design flexibility due to the extended product portfolio.
The 100 V OptiMOS 5 Linear FET 2 is available in a TO-leadless package (TOLL) and offers a 12 times higher SOA at 54 V at 10 ms and 3.5 times higher SOA at 100 µs compared to a standard OptiMOS 5 with similar R DS(on). The latter improvement is particularly important for the battery protection performed inside the battery management system (BMS) in case of a short circuit event. During such events the current distribution between parallel MOSFETs is critical for the system design and reliability.
The OptiMOS 5 Linear FET 2 features an optimized transfer characteristic that allows for improved current sharing. Taking into account the wide SOA and improved current sharing, the number of components can be reduced by up to 60 percent in designs where the number of components is determined by the short-circuit current requirement. This enables high power density, efficiency, and reliability for battery protection which are used in a wide range of applications including power tools, e-bikes, e-scooters, forklifts, battery back-up units and battery-powered vehicles.
The new OptiMOS 5 Linear FET 2 MOSFET is now available. Further information can be found at www.infineon.com/optimos-linearfet and www.infineon.com/ipt023n10nm5lf2.

The package enables a simple and compact double-sided PCB design and minimizes cooling requirements and system costs for future automotive power designs. The SSO10T TSC is therefore well suited for applications such as electric power steering (EPS), EMB, power distribution, brushless DC drives (BLDC), safety switches, reverse battery, and DCDC converters.
The SSO10T TSC has a 5 x 7 mm² footprint and is based on the established industry standard SSO8, a 5 x 6 mm² robust housing. However, due to its top-side cooling, the SSO10 TSC offers more than 20 percent and up to 50 percent higher performance than the standard SSO8 – depending on the thermal interface (TIM) material used and the TIM thickness. The SSO10T TSC package is JEDEC listed for open market and provides wide second source compatibility. As a result, the package can be introduced quickly and easily as the future standard for top-side cooling.
The SSO10T package enables a very compact PCB design and reduces the system footprint. It also lowers the cost of the cooling design by eliminating vias, resulting in lower overall system costs and design effort. At the same time, the housing offers high power density and efficiency, thus supporting the development of future-proof and sustainable vehicles.

Artificial Intelligence is currently driving an exponential increase in global data generation, and consequently increasing the energy demands of the chips supporting this data growth. Infineon Technologies AG launched its TDM2254xD series dual-phase power modules that enable best-in-class power density, quality and total cost of ownership (TCO) for AI data centers.
The TDM2254xD series products blend innovation in robust OptiMOS TM MOSFET technology with novel packaging and proprietary magnetic structure to deliver industry-leading electrical and thermal performance with robust mechanical design. This lets data centers operate at higher efficiency to meet the high power demands of AI GPU (Graphic Processor Unit) platforms while also significantly reducing TCO.
Given that AI servers require 3 times more energy than traditional servers, and data centers already consume more than 2 percent of the global energy supply, it is essential to find innovative power solutions and architecture designs that further drive decarbonization. Paving the way for the green AI factory, Infineon’s TDM2254xD dual-phase power modules combine with XDP TM Controller technology to enable efficient voltage regulation for high-performance computing platforms with superior electrical, thermal and mechanical operation.
Infineon introduced the TDM2254xD series at the Applied Power Electronics Conference (APEC).

The electrification of the transportation system is advancing continuously. In addition to passenger cars, 2- and 3-wheelers as well as light vehicles are increasingly being electrified. Therefore, the automotive market for Electronic Control Units (ECUs) powered by 24 V-72 V is expected to keep growing in the coming years.
To address this development, Infineon Technologies AG is complementing its OptiMOS™ 5 portfolio of automotive MOSFETs in the 60 V and 120 V range with new products in the high power packages TOLL, TOLG and TOLT. They are offering a compact form factor with very good thermal performance combined with excellent switching behavior.
The six new products offer a narrowed gate threshold voltage (V GS(th)) enabling designs with parallel MOSFETs for increased output power capability. The IAUTN06S5N008, IAUTN06S5N008G and IAUTN06S5N008T are 60 V MOSFETs, and the IAUTN12S5N017, IAUTN12S5N018G and IAUTN12S5N018T are 120 V MOSFETs.
The on resistance (R DS(on)) ranges from 1.7 mΩ to 1.8 mΩ for the 120 V MOSFETs and is 0.8 mΩ for the 60 V MOSFETs. This makes the 60V MOSFETs perfectly suited for high power 24 V supplied CAV applications or for HV-LV DCDC converters in xEVs.
