SFH6106-1

Overview

The SFH6106-1 is a single-channel surface-mount optocoupler featuring an NPN phototransistor output. It provides 5300Vrms isolation voltage and operates within a temperature range of -55°C to 100°C. Key electrical parameters include a maximum forward current of 60mA, typical forward voltage of 1.25V, and collector-emitter saturation voltage of 400mV. The device exhibits a current transfer ratio of 40% to 80% at 10mA input, with typical rise and fall times of 2µs each.

Feature Summary

• High current transfer ratio for efficient signal transmission
• Low coupling capacitance to minimize interference
• High isolation voltage ensuring circuit safety
• End-stackable design compatible with standard spacing

Applications

• Signal transmission between electrically separated circuits
• General purpose digital signal isolation
• Industrial control system interfaces
• Power supply feedback loops

Procurement Notes

Verify the specific suffix matches the required current transfer ratio bin, as variants like SFH6106-1T differ from SFH6106-1. Confirm package type availability, noting that some distributors list tube packaging while others offer tape and reel options. Ensure compliance with RoHS3 standards if required by the target application environment.

Selection Notes

Select this component when high isolation voltage and fast switching speeds are required in a compact surface-mount footprint. Compare CTR specifications against other SFH6106 variants to ensure compatibility with drive circuit requirements. Consider thermal management capabilities given the wide operating temperature range and power dissipation limits.

Part Context

Part of the SFH610A/SFH6106 series designed for robust signal isolation. The SFH6106 variant specifically targets surface-mount applications, offering end-stackability for space-constrained designs. It serves as a modern alternative to through-hole equivalents, maintaining similar electrical performance characteristics in a smaller form factor.

Replacement Considerations

SFH6106-1T is a related variant with different CTR specifications. Verify exact CTR requirements before substitution, as the -1T version may not meet the 40-80% range specified for the -1 model. Check pinout compatibility and isolation voltage ratings to ensure functional equivalence in existing designs.
