The continuous progression of transportation electrification is underway. Alongside traditional passenger cars, electric power is increasingly being adopted by 2- and 3-wheelers as well as light vehicles. As a result, the market demand for Electronic Control Units (ECUs) operating within the 24 V to 72 V range is anticipated to keep expanding in the forthcoming years. Infineon Technologies AG has launched automotive MOSFETs designed for 60 V and 120 V applications to accommodate this trend.
The press release says that the on-resistance spans from 1.7 mΩ to 1.8 mΩ for the 120 V MOSFETs and maintains at 0.8 mΩ for the 60 V MOSFETs. This characteristic renders the 60 V MOSFETs exceptionally well-suited for high-power 24 V supplied applications in commercial autonomous vehicles (CAVs) or for high-voltage to low-voltage (HV-LV) DC-DC converters in electric vehicles (EVs). Meanwhile, the 120 V MOSFETs find application in traction inverters for two- or three-wheelers and lightweight electric vehicles, particularly those supplied with 48 V to 72 V power.
The company claims that the automotive MOSFETs, available in high-power packages denoted as TOLL, TOLG, and TOLT, offer a compact physical design alongside exceptional thermal performance, all combined with excellent switching characteristics. The six new products include a reduction in the gate threshold voltage, facilitating designs involving parallel MOSFETs to enhance output power capacity.
