SFH617A-3X017T

Overview

The SFH617A-3X017T is a single-channel optocoupler featuring an NPN phototransistor output and surface-mount packaging. It provides high isolation voltage of 5300Vrms, suitable for demanding applications. The device operates with a DC input and supports a maximum forward current of 60mA. Key electrical parameters include a typical rise time of 4.6µs and fall time of 15µs. The current transfer ratio ranges from 100% to 200%. It functions within a temperature range of -55°C to +110°C.

Feature Summary

• Provides robust electrical isolation via high dielectric strength between input and output circuits.
• Features fast switching characteristics with defined rise and fall times for signal integrity.
• Offers wide operating temperature range for stability in extreme environmental conditions.

Applications

• Industrial control systems requiring galvanic isolation
• Power supply feedback loops
• Signal transmission across isolated boundaries

Procurement Notes

Verify the specific suffix 'X017T' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 4-SMD package dimensions align with the target PCB footprint. Ensure compliance with RoHS3 standards if restricted substances are a constraint. Cross-reference the datasheet revision date to confirm parameter validity against current design requirements.

Selection Notes

Select this component when high isolation voltage and fast response are critical. Compare the CTR range against circuit gain requirements to ensure reliable saturation. Consider the thermal dissipation capabilities given the small surface-mount form factor. Evaluate the trade-off between speed and power consumption relative to other Vishay series options.

Part Context

This part belongs to the SFH617A series of Vishay optocouplers. It shares functional similarities with through-hole variants like VO617A but utilizes a surface-mount package for compact designs. The series is designed for general-purpose isolation tasks where space efficiency is prioritized without compromising electrical performance or safety ratings.

Replacement Considerations

Direct substitutes include VO617A-3X016 for through-hole implementations. For surface-mount equivalents, verify pinout compatibility with similar Vishay SOP-4 devices. Ensure replacement parts maintain the same isolation voltage rating and current transfer ratio specifications to avoid circuit redesign.
