Combining Lowest RDS(on) + SMT for Space-Limited, High-Performance Apps

Pete Losee, Director of Technology Development, Qorvo

The performance of wide band-gap (WBG) semiconductor switches such as silicon carbide cascode FETs (‘SiC FET’ henceforth) (Figure 1) and SiC MOSFETs is closely tied to its package. At the pure technology level, nanosecond switching speed and low specific on-resistance result in very low losses, allowing mu
