CQY80SMT&R

Overview

The CQY80SMT&R is a single-channel surface mount optocoupler manufactured by Isocom Components 2004 LTD. It features a phototransistor output and utilizes a 6-pin SMD package. The device provides an isolation voltage of 5300Vrms, ensuring robust electrical separation between input and output circuits. It supports a maximum DC forward current of 60 mA and delivers a collector output current of up to 50 mA. The unit operates within a temperature range of -55°C to 100°C. Key performance metrics include a minimum current transfer ratio of 40% and a maximum of 80% at 10 mA input. Typical switching characteristics include a rise time of 2µs and a fall time of 11µs.

Feature Summary

• Provides high-voltage electrical isolation via a 5300Vrms barrier between input and output sections.
• Integrates a phototransistor output stage capable of driving loads with up to 50 mA collector current.
• Designed for surface mount assembly using a compact 6-pin configuration.

Applications

• General-purpose signal isolation in industrial control systems
• Interface circuits for microcontrollers requiring galvanic separation
• Power supply feedback loops

Procurement Notes

Verify the specific suffix 'R' corresponds to the required tape-and-reel packaging format, as standard variants may use tubes. Confirm that the manufacturer designation Isocom Components 2004 LTD aligns with your approved vendor list. Ensure the component meets RoHS compliance requirements for your target market. Check for any obsolescence notices or lifecycle changes associated with this specific part number before finalizing procurement plans.

Selection Notes

Select this component when a surface mount solution is required for applications needing moderate speed and high isolation voltage. The 6-pin form factor suits space-constrained PCB layouts. Consider the 40-80% current transfer ratio range for biasing calculations. Verify that the 60 mA forward current limit accommodates the drive circuit capabilities. Compare against alternatives if lower propagation delays are necessary for high-speed digital signals.

Part Context

This device belongs to the CQY80 series of optocouplers, which are designed for general-purpose isolation tasks. The series typically offers a balance of cost-effectiveness and reliable performance for basic switching applications. The SMT&R variant specifically denotes the surface mount technology version packaged for automated assembly processes, distinguishing it from through-hole DIP equivalents.
