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. The 120 V MOSFETs are used in 48 V – 72 V supplied traction inverters for 2- or 3-wheelers and light electric vehicles.

A small footprint of discrete power MOSFETs plays a critical role in achieving space savings, cost reduction, and easy-to-design applications. Additionally, higher power density can lead to layout routing flexibility and overall system size reduction. By expanding the current PQFN 2×2 portfolio with the new best-in-class OptiMOS™ power MOSFETs, Infineon Technologies AG offers benchmark solutions optimized for efficiency and performance in a small footprint. The new products are ideal for applications like synchronous rectification in switched mode power supplies (SMPS) for servers, telecom, and portable- and wireless chargers. Additional applications also include electric speed controllers for small brushless motors in drones.
The new OptiMOS 6 40 V and OptiMOS 5 25 V and 30 V power MOSFETs further optimize the proven OptiMOS technology for high-performance designs. They offer leading-edge silicon technology, package reliability, and superior thermal resistance (R thJC, max = 3.2 K/W) in the ultra-small PQFN 2×2 mm² package. The new devices combine industry-leading low on-resistance R DS(on) with industry-leading figures of merit (FOMs, Q G and Q OSS) for outstanding dynamic switching performance. As a result, MOSFETs with ultra-low switching and reduced conduction losses ensure optimal energy efficiency and power density, all while simplifying thermal management.
With the compact PQFN 2×2 mm² package outline, the OptiMOS power switches enable an improved system form factor with smaller, more flexible geometric outlines for end-user applications. The MOSFETs facilitate reliable system design with less need for paralleling, significantly reducing space and system cost.
