onsemi Releases EliteSiC MOSFETs in T2PAK Top-Cool Package for EV, Solar and Energy Storage Applications

onsemi has launched its EliteSiC MOSFET portfolio in the T2PAK top-cool package for automotive and industrial high-power applications.

The initial devices are 650 V and 950 V EliteSiC MOSFETs with Rds(on) values ranging from 12 mΩ to 60 mΩ. The T2PAK package routes heat from the die through the top side directly to the system heatsink, bypassing PCB thermal limitations while maintaining low stray inductance.

The top-cool configuration is targeted at electric vehicle onboard chargers, DC-DC converters, solar inverters, energy storage systems, and industrial power supplies.

Initial devices are shipping to lead customers. Additional variants are scheduled for release in Q4 2025 and beyond.

Auggie Djekic, Vice President and Head of SiC Division at onsemi, stated: “With our EliteSiC technology and the innovative T2PAK top-cool package, customers can unlock superior thermal performance and design flexibility.”
