SFH6286-2T

Overview

The SFH6286-2T is a single-channel surface-mount optocoupler featuring an AC-input LED and NPN phototransistor output. It provides 5300Vrms isolation voltage with a typical rise time of 3.5μs and fall time of 5μs. The device supports a maximum forward current of 50mA and operates within a temperature range of -55°C to +100°C. Current transfer ratio ranges from 63% to 200%, ensuring reliable signal transmission in noise-sensitive environments.

Feature Summary

• AC input capability for direct mains or AC signal interfacing
• High isolation voltage rating for safety-critical applications
• Low coupling capacitance for high-speed noise immunity

Applications

• Mains-powered switch-mode power supplies
• Solid-state relay control circuits
• Industrial communication interface isolation

Procurement Notes

Verify the specific suffix '2' corresponds to the required current transfer ratio bin (63%-200%) rather than other variants like '-4'. Confirm package type matches design requirements, as tape-and-reel packaging may differ from tube configurations in equivalent part numbers. Ensure compliance with RoHS directives if applicable to the target market.

Selection Notes

Select this component when AC input driving is required without additional rectification circuitry. The NPN transistor output suits sinking current applications. Consider thermal management due to 150mW power dissipation limit. Verify that the 5300Vrms isolation meets system safety standards compared to lower-rated alternatives.

Part Context

Part of the Vishay SFH628 series designed for general-purpose isolation. The 'T' suffix typically indicates tape-and-reel packaging for automated assembly. This model differs from DC-input variants by its internal LED configuration optimized for alternating current signals.

Replacement Considerations

SFH6286-2 is the tube-packaged equivalent. SFH6286-4 offers different CTR specifications.
