SFH6106-1X001T

Overview

The SFH6106-1X001T is a single-channel surface-mount optocoupler featuring an NPN phototransistor output. It provides high isolation with a test voltage of 5300 VRMS and supports a maximum collector-emitter voltage of 70 V. The device operates within a temperature range of -55°C to 100°C, with a typical rise time of 2 µs and fall time of 2 µs. It accepts a maximum forward current of 60 mA and delivers a collector current up to 50 mA. The current transfer ratio ranges from 40% to 80% at 10 mA input, housed in a compact 4-SMD package.

Feature Summary

• Provides robust electrical isolation via a 5300 VRMS dielectric barrier between input and output circuits.
• Features low saturation voltage for efficient switching performance in digital signal applications.
• Delivers high linearity in current transfer characteristics relative to the forward input current.

Applications

• Industrial control systems requiring galvanic isolation
• Signal transmission across isolated power supply grounds
• Microcontroller interface circuits for noise immunity

Procurement Notes

Verify the specific suffix '1X001T' against the official Vishay datasheet to confirm the exact Current Transfer Ratio binning and packaging configuration. Ensure that the procurement source provides documentation confirming RoHS compliance and lead-free status as specified by the manufacturer. Cross-reference the part number with authorized distributors to validate authenticity and traceability before finalizing orders.

Selection Notes

Select this component when high isolation voltage and fast switching speeds are required in a small surface-mount footprint. The 70 V collector-emitter rating suits low-voltage logic interfacing. Consider the 40-80% CTR range for circuit design margins. Verify thermal management requirements given the 100°C maximum operating temperature limit and ensure the PCB layout accommodates the 4-SMD package dimensions.

Part Context

This part belongs to the Vishay SFH series of surface-mount optocouplers, designed for compact electronic assemblies. The SFH6106 variant specifically targets applications needing reliable signal isolation with moderate speed capabilities. It complements other devices in the family by offering a balance of high isolation voltage and standard transistor output characteristics suitable for general-purpose digital isolation tasks.

Replacement Considerations

Direct substitutes include the SFH6106-1X001 (non-tape version) or SFH6106-2X001T if different CTR binning is acceptable. Verify pinout compatibility and isolation ratings before substitution. No direct cross-brand equivalents are confirmed in public data without detailed parameter matching.
