Avago Technologies Launches 10 MBd Digital Optocoupler for High Insulation Voltage Applications

ACNV2601 is designed to provide 7,500 Vrms/1 minute isolation voltage, 1,768 Vpeak continuous working insulation voltage and 12,000 Vpeak transient over voltage. The ACNV2601 is pending IEC/UL/CSA regulatory certification for Reinforced Insulation against electric shock applications.



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 1,500 V.



10 MBd Optocoupler Applications

The high insulating voltages of the Avago ACNV2601 makes it suitable for applications with 690 V power main voltages or high speed, power switching equipment that use high voltage IGBTs. Applications like wind turbines, Intelligent Power Modules and communication interfaces, such as RS‑232/RS‑485 and CANBus, will benefit from the combined high speed and insulation voltage characteristics of the ACNV2601.



Where conventional line receivers cannot operate, the ACNV2601 provides reliable logic interfacing and input/output buffering in the presence of extremely high ground or induced noise.
