Professional magazine and portal dedicated to electronics onsemi Unveils World’s First TOLL-packaged 650 V Silicon Carbide MOSFET
onsemi announced the world’s first TO-Leadless (TOLL) packaged silicon carbide (SiC) MOSFET. The transistor addresses the rapidly growing need for high-performance switching devices that are suitable for designs with high levels of power density. Until recently, SiC devices had been supplied in D2PAK 7-lead packages which required significantly more space.
With a footprint of just 9.90 mm x 11.68 mm, the TOLL package offers 30% savings in PCB area over a D2PAK package. And at a profile of just 2.30 mm, it occupies 60% less volume than a D2PAK package.
In addition to its smaller size, the TOLL package offers better thermal performance and lower package inductance (2 nH) than a D2PAK 7-lead. Its Kelvin source configuration ensures lower gate noise and lower switching losses – including a 60% reduction in turn-on loss (Eon) when compared to a device without a Kelvin configuration, ensuring significant improvements in efficiency and power density in challenging power designs as well as improved EMI and easier PCB design (more info).
