SFH610A-3X006

Overview

The SFH610A-3X006 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output housed in a DIP-4 through-hole package. Key electrical parameters include a maximum collector-emitter voltage of 70 V, a maximum collector current of 100 mA, and a power dissipation of 150 mW. The device offers a high isolation voltage of 5300 Vrms and a current transfer ratio ranging from 100% to 200%. Typical switching times are 3 µs for rise time and 14 µs for fall time. It operates within a temperature range of -55°C to +100°C.

Feature Summary

• High isolation voltage capability for safe signal transmission across potential differences
• High current transfer ratio ensures efficient coupling between input and output circuits
• Low coupling capacitance minimizes interference in high-frequency applications

Applications

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

Procurement Notes

Verify the specific suffix X006 against official Vishay documentation to confirm packaging details such as tube quantity versus reel configuration. Ensure that the required isolation certifications (e.g., UL, CSA) match the intended regulatory compliance for the final equipment. Cross-reference the exact part number with the manufacturer's latest datasheet to confirm availability and any recent design changes.

Selection Notes

Select this component when high isolation voltage and moderate speed are required for DC or low-frequency signal isolation. Compare the 100 mA collector current limit against load requirements. Consider the DIP-4 package constraints for PCB layout. Evaluate the 5300 Vrms isolation rating against system safety standards. Verify thermal management needs given the 150 mW power dissipation rating.

Part Context

This component belongs to the SFH610A series of phototransistor output optocouplers. It is functionally equivalent to the VO610A-3 series, sharing similar electrical characteristics and pinouts. The SFH610A series is designed for general-purpose isolation applications where reliability and high isolation voltage are critical. It represents a standard solution for separating noisy digital or analog signals from sensitive control circuitry.

Replacement Considerations

The VO610A-3 is listed as a recommended alternative with identical electrical specifications. Verify pin compatibility and package dimensions before substitution. Confirm that the replacement part meets the same agency approvals required for the application.
