SFH610A-2X001

Overview

The SFH610A-2X001 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It integrates an infrared LED and an NPN phototransistor in a DIP-4 package for through-hole mounting. Key electrical specifications include a maximum collector-emitter voltage of 70 V, a maximum collector current of 100 mA, and a forward current of 60 mA. The device offers a high insulation voltage of 5300 Vrms and a typical power dissipation of 150 mW. Current transfer ratio ranges from 63% to 125%, with rise and fall times of 3 µs and 14 µs respectively. Operating temperature spans from -55°C to +100°C.

Feature Summary

• Provides galvanic isolation between input and output circuits using an infrared LED and NPN phototransistor configuration.
• Features high reliability construction suitable for demanding industrial applications requiring robust signal transmission.
• Delivers high current transfer ratio to ensure efficient signal coupling across the isolation barrier.

Applications

• Digital logic signal transmission and level shifting
• Power supply control and switching circuits
• Electrical insulation isolation between circuits and systems
• Impedance transformation in electronic interfaces

Procurement Notes

Verify the specific suffix X001 against manufacturer datasheets to confirm packaging type and binning. Ensure compatibility with DIP-4 through-hole assembly processes. Cross-reference part numbers with official Vishay documentation to distinguish between similar variants like SFH610A-3 or SFH610A-4 which may have different CTR ranges or timing characteristics.

Selection Notes

Select this component when high isolation voltage and reliable digital switching are required. Consider the 63-125% CTR range for circuit design margins. Verify that the 70 V collector-emitter voltage and 100 mA collector current meet load requirements. Check thermal constraints given the 150 mW power dissipation limit and operating temperature range.

Part Context

This part belongs to the SFH610A series of transistor output optocouplers. It shares the same physical footprint and basic functionality as other variants in the family, such as SFH610A-3 and SFH610A-4, but differs in current transfer ratio specifications and potentially timing parameters. The series is designed for general-purpose isolation tasks.

Replacement Considerations

Officially documented alternative part numbers include VO610A-3X001 and SFH610A-3. Verify that the replacement's current transfer ratio and switching speeds match the original design requirements before substitution.
