International Rectifier's single in-line package (SIP) handles multiple power die, a high voltage IC, and includes internal heat spreaders for the power die.
International Rectifier's 600V, 16A, and 20A integrated power modules (IPMs) address high-performance variable-speed motion control power stages for applications such as air conditioners and commercial freezers. To meet the requirements of variable speed motor drives for energy-efficient appliances operating from 85V to 253V ac, the IPMs integrate a high-voltage integrated circuit (HVIC) with a three-phase inverter power stage. The 16A device handles the 750W to 1.2 kW power range, while the 20A devices address 750W to 2.2 kW.
The highest performance and features are available in the IRAMY20UP60B, a 20A, 600V IPM with an internal shunt resistor for current sensing. This unit combines low VCE(on) non-punch-through and short-circuit-rated IGBT technology with a three-phase HVIC gate driver that provides over-current and over-temperature protection, as well as under-voltage lockout.
The unit comes in a 22-pin SIP3 package with a 78 ื 31.6 mm heatsink footprint and includes internal heat spreaders for the power die. The full-transfer mold design minimizes PCB space and simplifies heat sink isolation and mounting. The isolation voltage capability of the package exceeds 2,000 VRMS. For efficient operation, the maximum thermal resistance is 1.8 degrees C/W for each IGBT, 3 degrees C/W for each diode, and the typical case to heatsink thermal resistance is 0.1 degree C/W. Two other versions offer less features or lower power capability and are available in the more compact 62 ื 25.8 mm, 23-pin S1P2 outline.
By experimenting with the photovoltaic reaction in solar cells, researchers at MIT have made a breakthrough in energy efficiency that significantly pushes the boundaries of current commercial cells on the market.
In a world that's going green, industrial operations have a problem: Their processes involve materials that are potentially toxic, flammable, corrosive, or reactive. If improperly managed, this can precipitate dangerous health and environmental consequences.
With LEDs dropping in price virtually every year, automakers have begun employing them, not only on luxury vehicles, but on entry-level models, as well.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
