Low/Medium Voltage MOSFETs
Portfolio of comprehensive range of Low-medium voltage power Mosfets that delivers superior performance and reliability for switching applications. Our cutting-edge PowerTrench® T10 technology delivers industry leading RDS, higher power density, reduced switching losses and better thermal performance.
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.
