SFH608-5X007

Overview

The SFH608-5X007 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor with a base terminal for enhanced switching speed and control capabilities. The device provides high isolation voltage of 5300 Vrms, suitable for demanding industrial applications. Key electrical parameters include a minimum current transfer ratio of 250% at 1 mA forward current, ensuring efficient signal transmission. The component operates within a temperature range of -55°C to +100°C and is housed in a surface-mount 6-SMD package.

Feature Summary

• Integrated base terminal on the output phototransistor allows for faster switching speeds and improved linearity compared to standard configurations.
• High current transfer ratio design enables effective operation with low input currents, reducing power consumption in the LED driver circuit.
• Robust insulation capability supports safe galvanic isolation between input and output circuits in high-voltage environments.

Applications

• Industrial automation systems requiring reliable signal isolation
• Power supply feedback loops for voltage regulation
• Solid-state relay driver circuits

Procurement Notes

Verify the specific suffix X007 confirms the surface-mount packaging and tape-and-reel delivery format when sourcing. Confirm RoHS compliance status through official Vishay documentation prior to integration. Ensure the supplier provides valid traceability data for quality assurance purposes. Check for any recent lifecycle changes or obsolescence notices directly from the manufacturer before finalizing procurement plans.

Selection Notes

Choose this component when fast switching performance is critical due to its base-driven output structure. The high CTR specification makes it suitable for low-power LED drive scenarios where minimal input current is required. Consider the 6-SMD footprint constraints during PCB layout design. Validate that the 5300 Vrms isolation rating meets the safety requirements of the target application environment.

Part Context

The SFH608 series represents Vishay's offering for high-performance optocouplers with integrated base terminals. This family is designed to bridge the gap between standard phototransistor outputs and logic-output devices, providing better speed than basic types while maintaining simplicity. The SFH608-5X007 variant specifically addresses surface-mount assembly needs within this product line.

Replacement Considerations

Direct substitutes may include other Vishay SFH608 variants with different packaging options such as SFH608-5 for through-hole applications. Cross-brand replacements require careful verification of pinout compatibility, isolation voltage ratings, and current transfer ratio specifications to ensure functional equivalence in the existing circuit design.
