The new package was developed specifically for the company’s SP6LI product family with 2.9 nanohenry (nH) stray inductance suitable for SiC MOSFET technology and enable high current, high switching frequency as well as high efficiency.
The SP6LI family features five standard modules, offering phase leg topology ranking from 1200V, 210A to 586A at a case temperature (Tc) of 80ºC to 1700V, 207A at Tc of 80ºC. The new package enables fewer modules to be used in parallel to achieve complete systems, reducing equipment size.
The modules can be used in switch mode power supplies and motor control in a variety of industrial, automotive, medical, aerospace and defense applications. Examples include electric vehicle/hybrid electric vehicle (EV/HEV) powertrain and kinetic energy recovery systems (KERSs); aircraft actuation systems; power generation systems; switched mode power supplies for applications including induction heating, medical power supplies and electrification of trains; photovoltaic (PV)/solar/wind converters and uninterrupted power supply (UPS).
“Our extremely low stray inductance standard SP6LI package is ideal for improving the performance of SiC MOSFETs for high switching, high current and high efficiency applications, offering a smaller sized power systems solution which can help customers significantly reduce their equipment needs,” said Leon Gross, vice president and business unit manager for Microsemi's Discrete and Power Management business unit. “These superior switching characteristics of our low inductance package enable customers to develop higher performance and highly reliable systems to help differentiate them from the competition.”
According to market research firm Technavio, the global SiC market for semiconductor applications is expected to reach nearly $540.5 million by 2021, growing at a compound annual growth rate (CAGR) of more than 18 percent. In addition, IHS Markit’s research indicates by 2025 SiC MOSFETs are forecast to generate revenue exceeding $300 million, almost reaching the levels of Schottky diodes to become the second best-selling SiC discrete power device type.
