Overview
The SFH6106-4T is a single-channel surface-mount optocoupler featuring an infrared LED input and NPN phototransistor output. It provides high isolation voltage of 5300 Vrms and operates within a temperature range of -55°C to +100°C. Key electrical parameters include a maximum forward current of 60 mA, typical forward voltage of 1.25 V, and collector-emitter saturation voltage of 400 mV. The device exhibits a current transfer ratio between 160% and 320% at 10 mA input, with typical rise and fall times of 2 µs each.
Feature Summary
- High isolation voltage capability for safe signal transmission across potential barriers
- Low coupling capacitance design minimizes high-frequency noise interference
- High current transfer ratio ensures efficient signal coupling with low input drive requirements
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops for voltage regulation
- Signal isolation in communication interfaces
Procurement Notes
Verify the specific suffix '4T' against the official Vishay datasheet to confirm pinout and packaging configuration. Ensure compliance with RoHS3 standards if required by your manufacturing process. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm that the 4-SMD package dimensions match your PCB footprint requirements before finalizing procurement.
Selection Notes
Select this component when high isolation voltage and fast switching speeds are critical. The NPN phototransistor output suits applications requiring digital signal isolation. Consider the operating temperature range and current transfer ratio variations when designing biasing circuits. Verify compatibility with system voltage levels and ensure adequate thermal management for continuous operation.
Part Context
The SFH6106 series belongs to Vishay's SFH family of surface-mount optocouplers. This series is designed for applications demanding high reliability and compact form factors. The SFH6106-4T variant specifically utilizes a 4-SMD package, distinguishing it from DIP versions like the SFH610A. It shares core performance characteristics with other members of the SFH6106 family while offering optimized mounting solutions for automated assembly processes.
Replacement Considerations
SFH6106-3T offers similar isolation but different current transfer ratio specifications. SFH6106-4X001T is a tube-packaged equivalent with identical electrical performance. Verify pinout compatibility and package dimensions before substitution.
