SFH609-1XSM

Overview

The SFH609-1XSM is a single-channel optocoupler manufactured by Isocom Components, featuring an infrared LED input and a phototransistor output. It utilizes a surface-mount DIP-6 package configuration designed for automated assembly processes. The device provides electrical isolation with a maximum insulation voltage of 2800 Vrms. Key electrical parameters include a maximum forward current of 60 mA, a rated current transfer ratio of 40%, and a collector-emitter breakdown voltage of 70 V minimum. Operating temperature range spans from -55°C to 100°C.

Feature Summary

• Integrates an infrared emitting diode with a phototransistor for signal transmission across isolated circuits
• Provides high-voltage electrical isolation between input and output sections
• Designed for surface-mount technology (SMT) applications using a compact six-pin package
• Capable of operating within extended industrial temperature ranges

Applications

• Industrial control systems requiring galvanic isolation
• Power supply units for feedback loop isolation
• Signal transmission in noisy electromagnetic environments
• General-purpose digital communication interfaces

Procurement Notes

Verify the specific suffix 'XSM' against official Isocom documentation to confirm surface-mount pinout and reel specifications. Ensure compliance with RoHS directives if required by the target application. Cross-reference the datasheet for exact mechanical dimensions to validate PCB footprint compatibility before procurement.

Selection Notes

Select this component when a surface-mount solution is required for single-channel isolation with moderate speed requirements. Consider the 40% current transfer ratio for drive circuit design. Verify that the 2800 Vrms isolation rating meets the safety standards of the end equipment. Compare thermal performance against through-hole alternatives if space constraints are critical.
