Microsemi Corporation announced its extremely low inductance package dedicated to high current, low specific on-resistance (RDSon) Silicon Carbide (SiC) MOSFET power modules. The new package, developed specifically for the company's SP6LI product family, is designed to offer 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 power modules in the new packaging, along with other SiC power modules from Microsemi's existing product family, will be showcased June 5-7 in hall 6, booth 318 at PCIM Europe 2018, held at the Exhibition Centre in Nuremberg, Germany.
As Microsemi continues to expand its SiC solutions, it has become one of the few suppliers providing a range of Si/SiC power discrete and module solutions to the market. With one of the lowest stray inductance packages in the industry dedicated to high current SiC MOSFET power modules, Microsemi's SP6LI product family features five standard modules, offering phase leg topology ranking from 1200 volts (V), 210 amperes (A) to 586 A at a case temperature (Tc) of 80 degrees Celsius to 1700 V, 207 A at Tc of 80 degrees Celsius. Offering higher power density and a compact form factor, the new package enables lower quantity of modules in parallel to achieve complete systems, helping customers to further downsize their equipment.
Microsemi's SP6LI power 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).
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.
The SP6LI power modules from Microsemi feature a phase leg topology made of SiC power MOSFETs and SiC Schottky diodes, and offer an extremely low RDSon down to 2.1 mOhms per switch and an internal thermistor for temperature monitoring. They also offer screw-on terminals for both signal and power connections, as well as isolated and high thermal conductivity substrates (Aluminum Nitrate as a standard and Silicon Nitride as an option) for improved thermal performance. In addition, the standard copper base plate can be replaced as an option with Aluminum Silicon Carbide (AlSiC) material enabling higher power cycling capabilities.
Other key features include:
Microsemi's product experts will be at the company's booth at PCIM during show hours to showcase its next-generation SiC solutions, including its new low inductance SiC-based SP6LI power module. In addition, the company's recently announced next-generation 1200 V, 40 mOhm SiC MOSFET device and 1200V, 10/30/50A SiC diode product will be showcased along with a power factor correction (PFC) reference design.
