 ACNV2601 optocoupler

Avago Technologies released of a 10MBd digital optocoupler with high insulation voltage ratings for power supply and high-power motor control application.

The ACNV2601 single-channel, 10MBd digital optocoupler addresses growing market segments that need high data communication rates along with high insulation voltage performance. The ACNV2601 combines 10MBd data rates while maintaining or increasing insulating voltage ratings.

ACNV2601 is designed to provide 7,500Vrms/1 minute isolation voltage, 1,768Vpeak continuous working insulation voltage and 12,000Vpeak 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 LED and photo-detector helps guarantee 20,000V/?s common-mode transient immunity performance with a common-mode voltage of 1,500V.

The high insulating voltages of the Avago ACNV2601 makes it suitable for applications with 690V 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.

The device features 2mm internal package distance-through-insulation, 13mm minimum package creepage and clearance with 5V supply operation. The ACNV2601 comes in 10-pin wide body DIP package with gull wing SMD lead option and operated at -40C to 105C. A 10-pin wide body (500 mil) DIP package is offered along with a gull wing lead option for standard surface mount processes.

Avago's ACVN2601 are priced at $2.17 each in 10,000-piece quantities. Samples and production quantities are available now through Avago's direct sales channel and worldwide distribution partners.
