SiC Combo JFETs - low RDS(on) SiC JFET with a Si MOSFET in a single compact package
SiC combo-FETs represent a revolutionary advancement, combining our low RDS(on) SiC JFET with a Si MOSFET in a single, compact package. Specifically designed for low-frequency protection applications, such as Power Supply Units (PSUs), downstream high-voltage DC-DC converters for AI Data Center Racks, Solid-State Circuit Breakers (SSCBs), EV battery disconnects, and surge protection, these combo-FETs allow users to access the JFET gate for optimized design. The integration of the Si MOSFET ensures a normally-off solution, achieving a size reduction exceeding 25% compared to discrete implementations.
