Silicon Carbide (SiC) Cascode JFETs
Our high-performance SiC cascode JFETs deliver best-in-class switching speed, lower switching losses, and higher efficiency. They provide high switching frequency and deliver ultra-low on-resistance (RDS (on)) starting at just 5mohm, utilizing less than half the die size of any other technology. Available in both standard thru-hole (including Kelvin) and surface mount packages, they offer excellent cost-effectiveness. These devices utilize a unique cascode configuration, integrating a high-performance SiC fast JFET with a cascode-optimized Si-MOSFET. This innovative approach enables standard gate drive (0-12V) for SiC devices. Given their smaller die size and compatibility with existing driver solutions, the SiC cascode JFETs offer optimized system performance and cost structure.
Silicon Carbide (SiC) MOSFETs

Our SiC MOSFETs are designed to be fast and rugged and include system benefits from high efficiency to reduced system size and cost. MOSFETs are metal–oxide–semiconductor field-effect transistors with insulated gates. These silicon carbide MOSFETs have a higher blocking voltage and higher thermal conductivity than silicon MOSFETs, despite having similar design elements. SiC power devices also have a lower state resistance and 10 times the breakdown strength of regular silicon. In general, Systems with SiC MOSFETs have better performance and increased efficiency when compared to MOSFETs made with silicon material.

There are many advantages to choosing SiC MOSFETs over silicon MOSFETs, such as higher switching frequencies. High-temperature development is also not a concern when using SiC MOSFET modules because these devices can operate efficiently even in high heat. Additionally, with SiC MOSFETs, you benefit from a more compact product size because all components (inductors, filters, etc.) are smaller.

Silicon Carbide (SiC) JFETs
Our SiC JFETs are high-performance, normally-on JFET transistors with VDS-max ranging from 650V to 1700V. They provide high switching frequency and deliver ultra-low on-resistance (RDS (on)) starting at just 4 mohm, utilizing less than half the die size of any other technology. Additionally low gate charge (Qg) enables further reductions in both conduction and switching losses. SiC JFETs are optimized for one of the uses in Power Supply Units (PSUs) and downstream high-voltage DC-DC conversion to handle the enormous power requirements of future AI Data Center Racks. In addition, they improve efficiency and safety by replacing multiple components with a solid-state switch based on SiC JFETs in EV battery disconnect units. Furthermore, they enable certain Energy Storage topologies and Solid-State Circuit Breakers (SSCBs).
Silicon Carbide (SiC) Combo JFETs
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.
