SFH6286-3X001T

Overview

The SFH6286-3X001T is a single-channel transistor output optocoupler from Vishay, designed for surface-mount applications. It features an NPN phototransistor output with a high current transfer ratio ranging from 100% to 320%. The device provides robust electrical isolation of 5300 Vrms and supports AC input signals. Key electrical parameters include a maximum collector-emitter voltage of 55 V, a forward current of 50 mA, and a typical rise time of 3.5 µs. It operates within a temperature range of -55°C to +100°C and is housed in a compact 4-SMD package.

Feature Summary

• High current transfer ratio ensures efficient signal transmission between isolated circuits.
• AC input capability allows direct coupling with alternating current sources without additional conditioning.
• Strong insulation voltage rating provides reliable protection against high potential differences.
• Fast switching speeds support data integrity in medium-speed digital communication interfaces.

Applications

• Solid-state relay driver circuits
• Microcontroller interface isolation
• Power supply feedback loops
• Industrial control system signal isolation

Procurement Notes

Verify the specific suffix '3X001T' to confirm the tape-and-reel packaging configuration, as standard versions may differ. Ensure compatibility with surface-mount assembly processes by checking the recommended soldering profile for the 4-SMD package. Cross-reference the manufacturer's latest datasheet for any updates on mechanical dimensions or thermal characteristics before finalizing the design.

Selection Notes

Choose this component when high CTR and AC input compatibility are required for space-constrained designs. The 5300 Vrms isolation rating makes it suitable for mains-connected applications. Consider the 3.5 µs rise time for timing-critical applications. Verify that the 55 V collector-emitter voltage meets the load requirements of the target circuit.

Part Context

This part belongs to the SFH series of optocouplers, which are widely used in industrial and consumer electronics for galvanic isolation. The SFH6286 variant specifically targets applications requiring high reliability and fast response times. It complements other Vishay optocouplers like the SFH6186 and SFH6286-3T, offering different packaging options such as tubes or reels to suit various production needs.

Replacement Considerations

The SFH6286-3T is a related variant with identical electrical specifications but may differ in packaging. Verify pinout compatibility and mounting style when substituting. Other Vishay models in the SFH family should be evaluated based on their specific isolation voltages and CTR ranges to ensure functional equivalence.
