Avago has released a 10 Mbps digital optocoupler with high insulation voltage ratings for power supply and high-power motor control application. The ACNV2601 single-channel optocoupler is designed to provide 7500 Vrms/1 minute isolation voltage, 1768 Vpeak continuous working insulation voltage and 12 000 Vpeak transient over-voltage. Avago’s proprietary internal shield between the AlGaAs light emitting diode and photo-detector helps guarantee 20 000 V/μs common-mode transient immunity performance with a common-mode voltage of 1500 V. The high insulating voltages of the ACNV2601 make it suitable for applications with 690 V power main voltages or high-speed power switching equipment that use high-voltage IGBTs. Applications include wind turbines, intelligent power modules and communication interfaces such as RS232/RS 485 and CANBus.
