Overview
The SFH617A-3X017 is a Vishay Semiconductor Opto Division single-channel optocoupler featuring an infrared LED and NPN phototransistor output. It utilizes a surface-mount 4-SMD package with a gull-wing configuration. Key electrical parameters include a maximum collector-emitter voltage of 70 V, a forward current of 60 mA, and a typical forward voltage of 1.65 V. The device offers a high current transfer ratio ranging from 100% to 200%. It provides robust isolation with a rated voltage of 5300 Vrms. Operating temperatures span from -55°C to 110°C, ensuring reliability in demanding environments.
Feature Summary
- High isolation voltage capability for safe signal transmission across potential barriers
- Wide operating temperature range suitable for industrial applications
- Compact surface-mount footprint for automated assembly integration
Applications
- Industrial control systems requiring galvanic isolation
- Signal interface circuits between microcontrollers and power stages
- Communication equipment needing noise immunity
Procurement Notes
Verify the specific suffix X017 confirms the 4-SMD gull-wing package variant. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the ordering quantity matches the standard tape-and-reel specifications provided by the supplier. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing procurement orders.
Selection Notes
Select this component when a surface-mount solution is required instead of through-hole alternatives like the SFH617A-3X016. Consider the 70 V collector-emitter voltage limit against load requirements. Evaluate the 100-200% CTR range for sufficient gain in the target circuit design. Compare rise and fall times against signal speed requirements for the specific application context.
Part Context
This part belongs to the Vishay SFH series of transistor-output optocouplers. It serves as the surface-mount equivalent to the through-hole SFH617A-3X016. The series is designed for general-purpose isolation tasks. It shares functional similarities with other Vishay devices but differs in packaging and specific pinout configurations.
Replacement Considerations
The VO617A-3X016 is documented as a recommended alternative. Verify package compatibility and pin alignment before substitution. Check if the replacement meets all isolation voltage and thermal requirements.
