SFH617A-3X001

Overview

The SFH617A-3X001 is a single-channel transistor output optocoupler from Vishay, housed in a 4-pin PDIP package. It features an NPN phototransistor output with a maximum collector current of 50mA and a collector-emitter voltage of 70V. The device provides high isolation capability with a test voltage of 5300 VRMS. Key electrical parameters include a forward voltage of 1.65V, a maximum forward current of 60mA, and a saturation voltage of 250mV. The current transfer ratio ranges from 100% to 200%. Operating temperatures span from -55°C to +110°C.

Feature Summary

• High isolation voltage rating of 5300 VRMS for robust circuit separation
• Wide operating temperature range extending to 110°C for demanding environments
• High current transfer ratio ensuring efficient signal transmission

Applications

• Industrial control systems requiring galvanic isolation
• Power supply feedback loops
• Signal isolation in microprocessor interfaces

Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm pinout and isolation ratings. Ensure the procurement channel provides original manufacturer packaging. Cross-reference the part number with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status if required by your manufacturing standards. Validate that the DIP-4 package matches your PCB footprint requirements before finalizing orders.

Selection Notes

Select this component when high isolation voltage and wide temperature operation are critical. The PDIP package suits through-hole assembly processes. Compare the 5300 VRMS rating against system safety requirements. Consider the 100-200% CTR range for logic level compatibility. Evaluate the 50mA output current capacity against load requirements. Verify thermal management needs given the 110°C maximum junction temperature limit.

Part Context

This part belongs to the SFH617A series of transistor output optocouplers. It shares functional similarities with other Vishay devices like the VO617A but differs in packaging and specific electrical characteristics. The SFH617A series is designed for general-purpose isolation applications. It complements Vishay's broader portfolio of optoelectronic components. The DIP-4 format distinguishes it from surface-mount variants in the same family.

Replacement Considerations

Official substitutes include the VO617A-3X016. Verify pin compatibility and isolation ratings before substitution. Check datasheet differences for CTR and voltage specifications.
