Core Product Advantages

AVAGO’s optocoupler portfolio spans diverse technologies and form factors to meet varied application demands:

High isolation voltage: Up to 15kVrms, effectively isolating high-voltage and low-voltage domains to prevent device damage from voltage spikes.

Wide operating temperature range: -40℃~125℃, suitable for extreme environments such as industrial high-temperature workshops and automotive engine compartments.

Multiple package options: Surface-mount technology (SMT), through-hole, and compact designs, compatible with space-constrained IoT devices and precision instruments.

Compliance certifications: AEC-Q101 (automotive-grade), ISO 13485 (medical-grade), meeting strict industry standards.

Real-World Application Cases

1. Industrial Automation: Isolation Between PLCs and Servo Drives

A leading global industrial automation company adopted AVAGO’s HCPL-7840 series high-speed optocouplers for signal transmission between its PLCs (Programmable Logic Controllers) and servo drives. Supporting a transmission rate of 100Mbps and an isolation voltage of 5kVrms, this product effectively suppresses electromagnetic interference (EMI) in industrial settings, avoiding equipment malfunctions caused by signal distortion. Currently, this solution is widely used in automotive production lines, robotic arm control, and warehouse logistics sorting systems, helping customers reduce equipment failure rates by 30%.

2. Automotive Electronics: EV Battery Management Systems (BMS)

In the battery management systems of new energy vehicles, AVAGO’s ACPL-796J series automotive-grade optocouplers perform critical isolation tasks. Compliant with AEC-Q101 standards, the product operates stably within a wide temperature range of -40℃~125℃, isolating the high voltage of the battery pack (up to 800V) from the vehicle’s low-voltage control system (12V/24V) to prevent safety risks from high-voltage leakage. After adopting this solution, a leading automaker not only passed the ISO 26262 functional safety certification but also improved battery energy management efficiency, extending the driving range by approximately 5%.

3. Medical Devices: Signal Isolation in Patient Monitors

Medical devices have extremely strict requirements for electrical safety. A medical equipment manufacturer selected AVAGO’s HCPL-0660 series medical-grade optocouplers for its multi-parameter patient monitors. With an isolation voltage of 8kVrms and leakage current less than 1μA, the product effectively isolates the monitor’s internal power circuits from the sensing circuits in direct contact with patients, eliminating the risk of electric shock. Meanwhile, its low-noise characteristics ensure accurate collection of physiological signals such as heart rate and blood pressure, helping the device obtain FDA and CE certifications. It is now used in intensive care units of hospitals worldwide.

4. Power Supplies: Noise Suppression in AC-DC Switching Power Supplies

A power supply manufacturer integrated AVAGO’s 6N137 series high-speed optocouplers into its industrial-grade AC-DC switching power supplies for signal isolation in feedback loops. The product suppresses conducted and radiated interference generated during power conversion, reducing the power output ripple to less than 50mV and meeting the high stability requirements of industrial equipment for power supplies. This solution has been mass-applied in server power supplies, industrial inverter power supplies, and other scenarios, reducing customer complaint rates by 40%.
