Avago Technologies, a supplier of analog interface components for communications, industrial and consumer applications, has released a new optocoupler available in special packages designed for use in renewable energy applications.
The new ACNV4506 optocoupler provides electrical signal isolation as an intelligent power module interface or insulated gate bipolar transistor (IGBT) gate drive in wind turbines, renewable energy harvesting sites and other industrial control applications.
These applications are increasingly using a 1700V IGBT, which requires higher creepage and clearance – the distance between conductive parts in a design – according to Avago. The ACNV4506 optocoupler is available in a 500 mil, 10-pin dual-inline package as well as a gull-wing lead option for standard surface mount processes, both with 13-mm creepage and clearance that meets the IEC60664-1 standard.Â
The high insulating voltages of the device make it suitable for applications with 690V power main voltages. In addition to high-insulation ratings, the device's packages provide distance through insulation of 2 mm, meeting EN50178 regulatory standards.Â
