Microchip Technology 1200V SIC MOSFETs
Microchip Technology 1200V SIC MOSFETs offer high efficiency in a lighter, more compact solution. The devices supply low internal gate resistance (ESR), resulting in a fast switching speed. The MOSFETs are simple to drive and easy to parallel, with improved thermal capabilities and lower switching losses.
The Microchip 1200V SIC MOSFETs eliminate the need for an external freewheeling diode and provide superior avalanche ruggedness in a fast and reliable body diode.
The TO-247-4 Notch package enables efficient, high-power designs with improved thermal performance and reduced parasitic effects. Its four-lead layout includes a Kelvin source to reduce gate ringing and switching losses, while the Notch design enhances creepage distance for improved high-voltage reliability.
The QDPAK package is a compact, surface-mount, top-side cooled solution designed to maximize the performance advantages of silicon carbide devices in high-power applications. It enables a direct thermal path from the device to an external heatsink, decoupling heat dissipation from the PCB and improving thermal performance, power density, and layout flexibility. The package also reduces parasitic inductance, supports fast switching, and simplifies automated assembly, while its emerging industry‑standard footprint allows scalable, multi-source designs and reduced system complexity.
