The IXFN70N120SK is a silicon carbide power MOSFET designed for high-voltage switching applications including solar inverters, motor drives, and UPS systems. It is packaged in an industry-standard SOT-227B (minibloc) housing with a backside aluminum nitride isolation layer and a Kelvin source connection for improved drive performance. The device supports a maximum drain-source voltage of 1200 V and a continuous drain current of 68 A at 25°C, with a maximum on-resistance of 34 mΩ at 25°C. It has a thermal resistance from junction to case of 0.45 K/W and operates reliably between -40°C and 150°C. The package provides 2500 V~ isolation between terminals and the backside, and meets UL 94 V-0 flammability standards. It is RoHS compliant.
Industrial grade, single switch SiC mosfet built in a 4 connectors, UL certified SOT227B package providing 3000V isolation (1s). Featuring a kelvin connection pin, and exhibiting good power cycling characteristics, and a very fast and low losses switching behaviour, this mosfets is recommend for use in high speed industrial switch mode power supplies and for pulsed power.
