Overview
The SFH6156-3TX001 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output housed in a compact 4-SMD surface-mount package. The device provides high isolation with a rated insulation voltage of 5300 Vrms. Key electrical parameters include a maximum collector-emitter voltage of 70 V, a maximum collector current of 50 mA, and a forward current rating of 60 mA. The typical forward voltage is 1.25 V, with a maximum saturation voltage of 400 mV. The Current Transfer Ratio (CTR) ranges from 100% to 200% at a forward current of 10 mA. Operating temperatures span from -55°C to +100°C.
Feature Summary
- High isolation voltage capability for safe signal transmission between isolated circuits
- Compact surface-mount design suitable for automated assembly processes
- Fast switching characteristics with defined rise and fall times for digital applications
Applications
- Industrial control systems requiring galvanic isolation
- Signal isolation in microprocessor-based interfaces
- Power supply feedback loops for noise immunity
Procurement Notes
Verify the specific suffix 'X001' against official Vishay documentation to confirm exact binning or packaging specifications. Ensure compatibility with RoHS directives if required by your application standards. Cross-reference datasheet revisions to confirm pinout consistency with existing designs. Confirm availability status as distribution data may vary.
Selection Notes
Select this component when high isolation voltage and moderate speed are required in a small footprint. Compare CTR ranges against load requirements to ensure sufficient gain. Verify thermal management capabilities within the specified operating temperature range. Consider alternative packages if through-hole mounting is preferred for mechanical stability.
Part Context
This part belongs to the SFH6156 series of transistor output optocouplers. The series offers various CTR bins and packaging options to suit different design needs. The SFH6156-3 variant specifically targets applications needing a CTR range of 100% to 200%. The TX001 suffix typically denotes tape and reel packaging for high-volume manufacturing.
Replacement Considerations
SFH6156-3T is a direct equivalent in terms of function and electrical characteristics. SFH6156-3X001T shares identical core specifications but may differ in packaging format. Verify pinout and isolation ratings before substituting with other Vishay models like the SFH6186 series.
