SFH609-4XSMT&R

Overview

The SFH609-4XSMT&R is a surface mount optocoupler manufactured by Isocom Components 2004 LTD. It features a single channel with a phototransistor output and an integrated base for enhanced switching performance. The device utilizes a 6-pin Surface Mount PDIP package. Key electrical specifications include a maximum forward current of 60 mA, a typical forward voltage of 1.25V, and a high isolation voltage of 5300 Vrms. The component offers a minimum current transfer ratio of 100% at 10mA input, with a maximum CTR of 500%. Switching characteristics include a typical rise time of 2.6µs and a fall time of 2.2µs.

Feature Summary

• Integrates a phototransistor with a dedicated base terminal to facilitate faster switching speeds and improved linearity compared to standard configurations.
• Provides robust electrical isolation capability rated at 5300 Vrms between the input LED and output transistor circuits.
• Designed for surface mount assembly using a compact 6-pin SMD package suitable for automated PCB manufacturing processes.

Applications

• Signal isolation in industrial control systems
• Interface circuits for microcontrollers and logic families
• Power supply feedback loops requiring galvanic isolation

Procurement Notes

Verify the specific suffix 'SMT&R' confirms the tape and reel packaging format required for your assembly line equipment. Confirm that the manufacturer designation matches Isocom Components 2004 LTD, as this part may be a rebranded version of Vishay components. Ensure the datasheet revision aligns with your design requirements before finalizing orders.

Selection Notes

Select this component when a phototransistor output with base access is necessary for speed or linearity improvements. The 5300 Vrms isolation rating supports applications demanding high safety standards. Compare the 100-500% CTR range against circuit gain requirements. Ensure the 60mA max forward current fits within the driving source capabilities.

Part Context

This component belongs to the SFH609 series of optically coupled isolators. It is functionally equivalent to the Vishay ILD2-X009T, sharing identical pinouts and electrical characteristics. The series is designed for general-purpose isolation tasks where moderate speed and high reliability are prioritized over ultra-high bandwidth applications.

Replacement Considerations

The Vishay ILD2-X009T is a confirmed direct substitute with matching specifications. Verify pin compatibility and thermal characteristics during replacement. Other SFH609 variants (e.g., SFH609-2) differ in CTR ranges and should be evaluated individually.
