Overview
The SFH617A-3X016 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductors. It features an NPN phototransistor output housed in a PDIP-4 through-hole package. Key electrical specifications 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 device offers a high isolation voltage of 5300 Vrms and a typical forward voltage of 1.65 V. Current transfer ratio ranges from 100% to 200%. Operating temperatures span from -55°C to +110°C.
Feature Summary
- High isolation voltage capability for safe signal transmission across potential barriers
- High current transfer ratio ensures efficient signal coupling between input and output stages
- Low coupling capacitance minimizes noise interference during operation
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops for voltage regulation
- Communication interfaces needing signal isolation
Procurement Notes
Verify the specific suffix (3X016) against official Vishay documentation to confirm the exact packaging configuration and lead time requirements. Ensure that the DIP-4 through-hole package aligns with your PCB assembly capabilities. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status if required for your manufacturing standards.
Selection Notes
Select this component when high isolation voltage and high current transfer ratio are critical for circuit performance. Consider the PDIP-4 package size constraints and through-hole mounting requirements. Evaluate the operating temperature range suitability for your specific environmental conditions. Compare the 70 V collector-emitter voltage limit against your circuit's maximum voltage spikes to ensure adequate safety margins.
Part Context
This component belongs to the SFH617 series of transistor output optocouplers from Vishay. It shares functional similarities with other devices in the family but differs in packaging and specific electrical ratings. The SFH617A variant typically denotes specific binning or performance characteristics within the broader product line. It serves as a standard solution for general-purpose isolation applications.
Replacement Considerations
Officially documented alternative part numbers include VO617A-3X016. Verify pinout compatibility and electrical parameter equivalence before substitution. Ensure that any replacement maintains the required isolation voltage and current transfer ratio specifications for your application.
