Overview
The SFH6156-1X001 is a single-channel surface-mount optocoupler featuring an AlGaAs infrared LED and an NPN silicon phototransistor. It provides high isolation voltage of 5300Vrms and operates within a temperature range of -55°C to +100°C. The device supports a maximum forward current of 60mA with a typical forward voltage of 1.25V. Current transfer ratio ranges from 40% to 80% at 10mA input. Switching characteristics include typical rise and fall times of 2µs, ensuring reliable signal transmission between isolated circuits.
Feature Summary
- High isolation voltage capability for safe circuit separation
- Low coupling capacitance for improved noise immunity
- Surface-mount packaging for automated assembly integration
Applications
- Signal transmission between electrically isolated circuits
- Industrial control system interface isolation
- Power supply feedback loop isolation
Procurement Notes
Verify the specific suffix X001 confirms the required current transfer ratio bin (40%-80%) and package variant. Ensure compatibility with standard SMD reflow profiles. Confirm RoHS compliance status matches project requirements. Cross-reference datasheet revision history for any recent parameter updates or pinout changes before finalizing procurement specifications.
Selection Notes
Select this component when high isolation voltage and moderate speed are required in a compact surface-mount form factor. Consider the 40-80% CTR range for logic-level interfacing. Evaluate thermal management needs given the 150mW power dissipation limit. Compare against through-hole alternatives if mechanical robustness during handling is a primary concern.
Part Context
This part belongs to the Vishay SFH6156 series of high-reliability optocouplers. The series offers various current transfer ratio bins and package options. The SFH6156-1X001 specifically denotes the surface-mount version with defined electrical characteristics suitable for general-purpose isolation applications requiring verified safety certifications.
Replacement Considerations
The VO615A-1X001 is listed as a recommended alternative. Verify pinout compatibility and electrical parameter equivalence before substitution. Ensure the replacement maintains the required isolation voltage and operating temperature range.
