SFH600-2G

Overview

The SFH600-2G is a single-channel optocoupler manufactured by Isocom Components, featuring an NPN phototransistor output and housed in a 6-pin DIP package. Designed for through-hole mounting, it accepts DC input with a maximum forward voltage of 1.65V and a maximum input current of 60 mA. The device provides high isolation capability with a minimum isolation voltage of 5300 Vrms. It exhibits a typical rise time of 2µs and a typical fall time of 11µs. The current transfer ratio ranges from a minimum of 200% to a maximum of 400%, ensuring reliable signal transmission across the isolation barrier.

Feature Summary

• Provides electrical isolation between input and output circuits using infrared light transmission.
• Utilizes an NPN phototransistor output stage for digital switching applications.
• Features a standard 6-pin dual in-line package suitable for through-hole PCB mounting.

Applications

• Industrial control systems requiring signal isolation
• Power supply feedback loops
• Solid-state relay driver circuits

Procurement Notes

Verify the specific suffix 'G' against the manufacturer's latest datasheet to confirm compliance with RoHS directives and halogen-free status. Ensure the ordering code matches the exact pin configuration and lead finish requirements for your assembly process. Cross-reference the part number with official distributor catalogs to confirm availability and authenticity before procurement.

Selection Notes

Select this component when a high current transfer ratio is required for efficient driving of downstream logic or relay coils. The 5300 Vrms isolation rating makes it suitable for applications demanding robust safety barriers. Consider the 6-pin DIP footprint compatibility with existing board layouts and ensure the NPN output polarity aligns with the circuit design requirements.

Part Context

This component belongs to the SFH600 series of optocouplers offered by Isocom Components. The series is designed as a replacement for legacy components, providing enhanced performance characteristics such as higher current transfer ratios compared to standard equivalents. The SFH600-2G variant specifically targets applications needing moderate speed and high gain within a standard DIP package format.

Replacement Considerations

Check for direct cross-references to standard CNY17 or SFH600 variants from other manufacturers. Verify that substitute parts maintain the same 6-pin DIP footprint and NPN output type. Confirm that the replacement meets the 5300 Vrms isolation requirement and similar current transfer ratio specifications.
