IR Introduces Ultra-fast Switching, Rugged 600V High Frequency IGBTs for Automotive Power Supply Applications

International Rectifier, IR® (NYSE: IRF), a world leader in power management technology, today introduced a highly innovative 600V automotive grade IGBT platform, COOLiRIGBT™ for use in a wide range of fast switching applications for electric (EV) and hybrid electric vehicles (HEV) including on-board DC-DC converters, motor drives, and battery chargers.

The new Gen. 1 COOLiRIGBT™ devices are capable of operating at the same fast switching speeds as MOSFETs while offering higher efficiency at high current levels. The first generation COOLiRIGBT™ devices cover a broad current range and offer a minimum short circuit rating of 5µs, low Vce(on) and positive Vce(on) temperature coefficient. Additional features common to the family include square reverse bias safe operating area (SRBSOA) and maximum junction temperature of 175°C. COOLiRIGBT™ also provides designers with the flexibility of selecting a diode with optimized performance for the application.

“With an extended temperature range of 175°C and much simpler and more rugged device structure, IR’s 200kHz capable COOLiRIGBT™s offer a superior and lower cost solution for fast switching applications such as HEV DC-DC converters or chargers and power supplies used in Plug-in-HEVs and EVs compared to super junction MOSFETs,” said Benjamin Jackson, Senior Power Switch Product Manager, IR’s Automotive Products Business Unit.

The AUIRGC655A1N0 is optimized for main electric and hybrid vehicle inverters and large motor drives while the AUIRGC65A20N0 and AUIRGC65G20N0 are targeted for power supply and high switching frequency applications. In addition to offering a higher maximum junction temperature and hard switching up to 200kHz, the two devices deliver improved performance of higher currents due to lower conduction losses and enhanced efficiency when used in resonant Zero Current Switching (ZCS) topologies.

IR’s automotive IGBTs are subject to dynamic and static part average testing combined with 100 percent automated wafer level visual inspection as part of IR’s automotive quality initiative targeting zero defects. The new devices are all environmentally friendly and assembled with IR’s automotive grade bill of materials which are lead-free and RoHS compliant.

Banner Engineering DF-G3 Discrete Fiber Amplifier Features World-Class Long Range Sensing Capability

Banner Engineering introduces its DF-G3 discrete long-range fiber amplifier with dual digital displays for use with plastic and glass fiber optic assemblies. Featuring increased sensing power, the DF-G3 can sense more than 3 meters (10 ft.) with opposed mode fibers or more than 1 meter (3 ft.) with diffuse mode fibers. The extra power provides increased detection reliability for dark targets at long range and enhanced detection sensitivity when using specialty fiber assemblies for large area and small part detection applications.

The DF-G3 is available with a single discrete output or two dual discrete outputs. The dual discrete outputs can be independently taught to trigger at different intensity values, which is ideal for correct part-in-place or error-proofing, bottle down, and edge guiding applications.

“We developed the DF-G3 fiber amplifier to meet our customers’ need to precisely detect smaller targets at longer ranges” said Dennis Smith, Senior Marketing Manager, Banner Engin…

TURCK M8 CORDSETS WITH 100 PERCENT SHIELDING OPTION PROTECT AGAINST EMI/RFI

TURCK is now offering the option to completely shield M8 picofast ® cordsets by connecting a braided shield directly to the coupling nut. This provides a cost-effective and reliable connection with 100 percent cable and connector shielding, which protects against electromagnetic and radio frequency interference.

The 3 and 4-pin cordsets are available with flexlife ® PVC or PUR jacketed cable. All connectors deliver IEC IP 67 protection.

The M8 picofast line, like most TURCK cordsets, provides male or female, straight and right angle connectors, standard and custom lengths, and pigtails or extensions. Fully encapsulated mating receptacles are also offered, completing the system.

IDEC Releases New Line of High Efficiency Power Supplies

IDEC Corporation announces the PS5R-V line of DIN-rail power supplies, offering their customers high-efficiency in a compact form factor at competitive prices. These power supplies suit a wide range of needs in the industrial marketplace, and carry all of the required certifications necessary for use in these demanding applications. This next generation of the industry standard PS5R power supply family has updated features and specifications to meet current and future needs.

The PS5R-V line of power supplies includes 10W, 15W, 30W, 60W and 120W versions, with additional versions coming soon.
