Microsemi, a provider of semiconductor solutions differentiated by power, security, reliability and performance, has introduced its new silicon carbide (SiC) MOSFET product family with new 1200 volt (V) solutions. The new SiC MOSFETs are designed for high-power industrial applications where efficiency is critical. These applications include solutions for solar inverters, electric vehicles, welding and medical devices.

Microsemi is well positioned to capitalise on SiC semiconductor market growth. Market researcher Yole Développement estimates that the SiC power semiconductor market will grow 39% year-over-year from 2015 to 2020, and Market Research estimates the SiC semiconductor market will grow 38% year-over-year to $5.3bn by 2022.


The new SiC MOSFETs provide patented technology from Microsemi and are designed to help customers develop solutions that operate at higher frequency and improve system efficiency.

Microsemi’s patented SiC MOSFET technology features include:

– RDS(on) vs. temperature

– Ultra-low gate resistance for minimising switching energy loss

– Superior maximum switching frequency

– Outstanding ruggedness with superior short circuit withstand

“Microsemi’s 1200V SiC MOSFETs are establishing a new benchmark for performance,” said Marc Vandenberg, general manager for Microsemi’s Power Products Group. “Microsemi continues to expand its SiC product portfolio by capitalizing on our in-house SiC fabrication capabilities and delivering high-power solutions to our customers.”

Microsemi’s 1200V SiC MOSFETs are rated at 80 milliohms and 50 milliohms and provide customers more development flexibility by offering both industry standard TO-247 and SOT-227 packages:

– APT40SM120B 1200V, 80milliohm, 40A, TO-247 package

– APT40SM120J  1200V, 80milliohm, 40A, SOT-227 package

– APT50SM120B  1200V, 50milliohm, 50A, TO-247 package

– APT50SM120J   1200V, 50milliohm, 50A, SOT-227 package

New SiC MOSFET Power Modules

SiC MOSFETs are also integrated into the company’s expanded MOSFET power modules, which are used in battery charging, aerospace, solar, welding and other high-power industrial applications. The new power modules provide higher frequency operation and improve system efficiency. 

New 1700V Schottky Diodes

Microsemi’s SiC MOSFETs are also complimented by Microsemi’s complete product line of SiC Schottky Diodes. The new 1700V SiC Schottky Diode expands the line beyond the 1200V and 650V. These products are designed with superior passivation technology for ruggedness in outdoor and humid applications.
