Mitsubishi Electric Power Module for Hybrid and Electric Vehicles Is Now Available in the Americas
Mitsubishi Electric Corp. recently launched a new transfer molded power module (T-PM) designed predominantly for hybrid and electric vehicle applications. The J-Series T-PM, incorporating Mitsubishi Electric’s proprietary technology which ensures power loss reduction, boasts a lifespan 30 times longer than industrial power modules and is also completely lead (Pb) free, including the terminal plating.
In the Americas, this new transfer molded power module is now available exclusively through Powerex, Inc. With its corporate headquarters located in Youngwood, Pennsylvania, southeast of the City of Pittsburgh, Powerex is the sales and logistics arm for Mitsubishi Electric Power Devices in the Americas.
Two Carrier-Stored Trench Gate Bipolar Transistor (CSTBT™) IGBT chips are incorporated in a 600V/300A power module. The J-Series T-PM (CT300DJH060) offers enhanced reliability by utilizing direct lead bonding (DLB), a technology developed by Mitsubishi Electric. DLB reduces power loss through decreasing wiring resistance and inductance in modules through the use of an extended main terminal made long enough to be bonded directly to the power chip. Previously, power chips were connected to the terminals by aluminum wire.
As referenced previously, the J-Series T-PM’s power cycle and temperature cycle lifespans are 30 times longer than those of typical industrial power modules. The power cycle lifespan is based on repetitive operation tests with the chip energized, rapidly changing the temperature within a range of 50-100°C. The temperature cycle lifespan is based on repetitive operation tests, modulating the temperature between -40 and 125°C without the chip energized.
In the expanding hybrid and electric vehicle market, automotive components are required to meet stringent safety standards, requiring power modules to be much more reliable than the standards required for industrial applications. Through its advanced technology, Mitsubishi Electric has achieved the quality and lifespan required for automotive applications. In 2004, through the use of transfer molding technology, Mitsubishi Electric was the first company to offer a highly reliable, lead (Pb)-free power module for automotive applications. With transfer molding – a process that enables the manufacturer to make multiple molds simultaneously, rendering power modules highly reliable –heated and pressurized resin is poured into a metal mold and then enclosed.
The traceability system for the J-Series T-PM enables management of material and components as well as the entire production process for each unit.
These products are available from stock to 12 weeks at $300 per device.

Energy Efficiency with Class D Amplifier Modules
Class-D switching amplifiers are helping audio designers create personal multimedia devices and home audio/visual systems that demonstrate how compact and stylish equipment can also deliver high sound quality and high audio output power. The key to this breakthrough, providing freedom from the large and bulky boxes housing traditional audio products, lies in the class-D amplifier’s high energy efficiency, which is typically around 90%. This allows designers to reduce or eliminate heatsinks as well as using smaller-sized PCBs and smaller components such as transformers, connectors and power supplies.

The Role of Hall Effect Sensors in Power Distribution Infrastructure
Power distribution units (PDUs) form an essential part of modern computing and data communications hardware. They provide multiple outputs for transferring electrical power with maximum efficiency, controlling the power capacity and safeguarding against the possible causes of supply interruption. With an ever increasing need from tech savvy consumers for higher data throughput and greater quantities of data storage capacity, as well as tough international legislation now governing CO&sub2; emissions, the demands being placed on these units are proving challenging for engineering teams to satisfy.
