Frequently Asked Questions

What are the advantages of SiC Schottky diodes over silicon diodes?

SiC Schottky diodes offer several advantages over silicon diodes including zero reverse recovery losses, higher temperature operation, and improved switching performance. The wide bandgap properties of SiC enable these improvements, making SiC diodes ideal for high-efficiency power conversion applications where silicon diodes would suffer from significant switching losses.

How do SiC diodes improve power converter efficiency?

SiC diodes improve power converter efficiency primarily through zero reverse recovery losses. Traditional silicon diodes have stored charge that must be removed during turn-on, causing significant switching losses. SiC Schottky diodes have no stored charge, eliminating these losses. Additionally, the higher switching frequencies enabled by SiC technology allow for smaller passive components and higher power density.

What is the significance of the TO-247-2L package?

The TO-247-2L package is a 2-lead version of the popular TO-247 package. It provides a robust mechanical interface and good thermal characteristics for reliable operation. The 2-lead configuration simplifies board layout compared to 3-lead packages while maintaining excellent thermal performance.
