650V industrial CoolSiC MOSFETs in TOLT and Thin-TOLL packages
Infineon Technologies has launched 650V silicon carbide MOSFETs in thin packages for industrial applications and AI power supplies.
The introduction of the Thin-TOLL 8×8 and TOLT packages boosts the space available on 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 discrete 650V CoolSiC MOSFET range with two new product families housed in the Thin-TOLL 8×8 and TOLT packages. These are based on the CoolSiC Generation 2 (G2) technology for high and medium switching-mode power supplies (SMPS), including AI servers, renewable energy, EV chargers, and large home appliances.
Infineon takes SiC MOSFET down to 400V for AI server power supplies
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 in AI and server power supply units (PSU), reducing 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.
The TOLT devices complete Infineon’s top-side cooled CoolSiC industrial portfolio alongside the 750V CoolSiC in a Q-DPAK package. This enables 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.
Infineon introduces next generation of SiC MOSFET technology
The CoolSiC MOSFETs 650 V G2 in ThinTOLL 8×8 and TOLT are now available in R DS(on) from 20, 40, 50 and 60 mΩ. Additionally, the TOLT variant is also available with an R DS(on) of 15 mΩ. The product family will be expanded by a more granular portfolio by the end of 2024.
Infineon will showcase the CoolSiC MOSFET 650 V Generation 2 at the PCIM exhibition in Nuremberg in Germany later this month.
