Mitsubishi Electric's SiC modules reduce power loss in diode and MOSFETs
Mitsubishi Electric Corporation will begin shipping samples of five kinds of power modules for home appliances and industrial equipment on July 31st, 2012.
The modules use SiC, a next generation semiconductor material expected to significantly reduce power loss in diode and metal oxide semiconductor field effect transistor (MOSFET) chips.
The modules will be showcased at POWER SYSTEM JAPAN 2012 in TECHNO-FRONTIER 2012, an exhibition on electro-mechanical parts and devices to be held between July 11th and 13th at Tokyo Big Sight in Japan.
SiC module for home appliances
Industrial hybrid SiC-IPM
Industrial full SiC module
Inverters are widely used in home appliances like air conditioners and refrigerators, as well as in industrial devices, to increase energy efficiency. Mitsubishi Electric says its SiC modules offer significant reductions in power loss and improvements in high speed switching, achieving even higher efficiency and downsizing.
Of the five new types of SiC power module samples, three types are for home appliances, while two are for industrial devices such as inverters and servos.

Product Features
1. SiC power module for home electronics
1-1. Hybrid SiC DIPIPM
• A SiC Schottky Barrier Diode (SBD) is used for the diode.
• Power loss is reduced by about 12% compared to DIPIPM using silicon (Si).
• The shape, size and pin configuration are the same as those of the Super mini DIPIPM.
• Offers the same protection as the Super mini DIPIPM using Si.
1-2. Hybrid SiC DIPPFC
• A SiC-SBD is used for the diode and achieves a maximum of 30kHz high-frequency switching.
• High-frequency switching contributes to the downsizing of peripheral components such as reactors and heat-sinks.
• The installation of a power factor correction (PFC) and driving IC contributes to downsizing through reduction of the mounting surface area and simplified wire patterning.
• Offers package compatibility with the Super mini DIPIPM using Si.
1-3.Full SiC DIPPFC
• SiC-MOSFET is used for the transistor, while SiC-SBD is used for the diode.
• Power loss is reduced by about 45% compared to products using Si.
• The adoption of SiC achieves a maximum of 50kHz high-frequency switching.
• High-frequency switching contributes to the downsizing of peripheral components such as reactors and heat-sinks.
• The installation of a PFC and driving IC contributes to downsizing through the reduction of mounting surface area and simplified wire patterning.
• Offers package compatibility with the Super mini DIPIPM using Si.
2. SiC power module for general industry
2-1. Hybrid SiC-IPM
• SiC-SBD is used for the diode.
• Power loss is reduced by about 25% compared to its predecessor PM75CL1A120 of the IPM L1 series, and contributes to the downsizing and improved product efficiency.
• The shape, size and pin configuration are the same as those of its predecessor PM75CL1A120 of the IPM L1 series.
• Offers the same protection as its predecessor PM75CL1A120 of the IPM L1 series.
2-2. Full SiC-Module
• SiC-MOSFET is used for the transistor and SiC-SBD is used for the diode.
• Power loss is reduced by about 70% compared to its predecessor CM400DY-24NF of the IGBT module (used in a parallel configuration), and contributes to improved product efficiency.
• Significantly reduces the size of packages, while reducing the mounting area by about 60% compared to its predecessor CM400DY-24NF of the IGBT module (used in a parallel configuration), and contributes to downsizing and weight reduction.
• Adopts a low inductance package to fully utilise the superior performance of SiC.
