Overview
The Vishay SFH6286-4 is a single-channel surface-mount optocoupler featuring an AC-input LED and NPN phototransistor output. It provides high isolation with a maximum rating of 5300 Vrms. The device supports a maximum forward current of 50 mA and offers a typical forward voltage of 1.5 V. Key electrical parameters include a collector-emitter saturation voltage of 400 mV, a minimum current transfer ratio of 160%, and a maximum of 500%. Timing characteristics specify a typical rise time of 3.5 µs and a fall time of 5 µs. It operates within a temperature range of -55°C to +100°C.
Feature Summary
- Integrated AC input capability for direct mains connection without external rectification
- High insulation voltage rating of 5300 Vrms for robust safety isolation
- NPN phototransistor output designed for logic-level interfacing
Applications
- Switch-mode power supply feedback circuits
- Solid-state relay driver interfaces
- Industrial control system signal isolation
Procurement Notes
Verify the specific ordering suffix to confirm packaging configuration, as standard tube and tape-and-reel variants exist within the product family. Confirm compliance requirements against target market certifications such as UL, VDE, or IEC standards prior to final procurement decisions.
Selection Notes
Select this component when AC-driven input isolation is required to simplify circuit topology. Ensure the 5300 Vrms isolation rating meets safety clearance requirements. Verify that the 160% minimum CTR is sufficient for the intended load current at the operating temperature extremes.
Part Context
This part belongs to the Vishay SFH628 series of optocouplers. It shares the same physical package and isolation architecture as related models like the SFH6186-4T, differing primarily in current transfer ratio specifications and input drive characteristics.
Replacement Considerations
SFH6286-4T serves as the tape-and-reel equivalent variant. Cross-reference with SFH6186-4T if higher volume packaging or specific CTR ranges are required.
