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.
With erupting concern over police brutality, law enforcement agencies are turning to body-worn cameras to collect evidence and protect police and suspects. But how do they work? And are they even really effective?
A half century ago, cars were still built by people, not robots. Even on some of the country’s longest assembly lines, human workers installed windows, doors, hoods, engines, windshields, and batteries, with no robotic aid.
DuPont's Hytrel elastomer long used in automotive applications has been used to improve the way marine mooring lines are connected to things like fish farms, oil & gas installations, buoys, and wave energy devices. The new bellow design of the Dynamic Tethers wave protection system acts like a shock absorber, reducing peak loads as much as 70%.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
