The electronics industry is witnessing a significant shift towards more compact and powerful systems, driven by technological advancements and a growing focus on decarbonization efforts. With the introduction of the Thin-TOLL 8×8 and TOLT packages, Infineon Technologies AG is actively accelerating and supporting these trends. They enable a maximum utilization of the PCB mainboard and daughter cards, while also taking the system’s thermal requirements and space restrictions into account. The company is now expanding its portfolio of CoolSiC MOSFET discretes 650 V with two new product families housed in the Thin-TOLL 8×8 and TOLT packages. They are based on the CoolSiC Generation 2 (G2) technology, offering significantly improved figures-of-merit, reliability, and ease-of-use. Both product families specifically target high and medium switching-mode power supplies (SMPS), including AI servers, renewable energy, EV chargers, and large home appliances.
The Thin-TOLL package has a form factor of 8×8 mm and offers the best-in-class Thermal Cycling on Board (TCoB) capability on the market. The TOLT package is a top-side cooled (TSC) enclosure with a similar form factor to TOLL. Both package types offer developers several benefits: Using them in AI and server power supply units (PSU), for example, reduces the thickness and length of the daughter cards and allows for a flat heat sink. When used in microinverters, 5G PSU, TV PSU and SMPS, the Thin-TOLL 8×8 package allows for a minimization of the PCB area occupied by the power supply devices on the mainboard, while TOLT keeps the junction temperature of the devices under control, given that these applications typically use convection cooling. In addition, TOLT devices complete Infineon’s top-side cooled CoolSiC industrial portfolio, namely CoolSiC 750 V in Q-DPAK. They enable developers to reduce the PCB footprint occupied by SiC MOSFETs when the power to be delivered to the devices does not require a Q-DPAK package.
Availability
The CoolSiC MOSFETs 650 V G2 in ThinTOLL 8×8 and TOLT are now available in RDS(on) from 20, 40, 50 and 60 mΩ. Additionally, the TOLT variant is also available with an RDS(on) of 15 mΩ. The product family will be expanded by a more granular portfolio by the end of 2024. More information is available at www.infineon.com/coolsic-gen2. Infineon will showcase the CoolSiC MOSFET 650 V Generation 2 at the PCIM in Nuremberg.
Infineon at the PCIM Europe 2024
PCIM Europe will take place in Nuremberg, Germany, from 11 to 13 June 2024. Infineon will present its products and solutions for decarbonization and digitalization in hall 7, booths #470 and #169. Company representatives will also be giving several presentations at the accompanying PCIM Conference and Forums, followed by discussions with the speakers.
