SFH6712

Logic Output Optoisolators Overview

The SFH6712 is a high-speed logic output optoisolator manufactured by Vishay Semiconductor Opto Division. It features a push-pull output configuration housed in an 8-DIP package with a 0.300-inch (7.62mm) width. The device provides electrical isolation of 5.3kV and supports data rates up to 5 MBd. Key electrical parameters include a maximum propagation delay of 300ns for both low-to-high and high-to-low transitions, a typical forward voltage of 1.4V, and a maximum DC forward current of 20mA. The output channel can handle up to 25mA. Operating temperature ranges from -40°C to 85°C, and it exhibits a common mode transient immunity of 1 kV/µs.

Logic Output Optoisolators Procurement Notes

Verify component status as the SFH6712 is officially listed as obsolete and no longer manufactured by Vishay. Confirm availability through authorized distributors or secondary market channels if immediate procurement is required. Ensure that any substitute components meet the original electrical specifications, particularly isolation voltage and data rate requirements, to maintain system performance and safety compliance.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is required with a push-pull output stage. Consider the 5.3kV isolation rating for safety-critical applications. Evaluate the 300ns propagation delay against system timing constraints. Verify that the 8-DIP package fits the PCB layout. Check thermal limits within the -40°C to 85°C operating range for the specific environment.

Logic Output Optoisolators Part Context

The SFH6712 belongs to the family of high-speed logic output optoisolators from Vishay. It is designed for applications requiring fast signal transfer across isolation barriers. The push-pull output distinguishes it from open-drain variants, offering stronger drive capabilities. It serves as a legacy solution for high-speed isolation before newer generations became available.

Logic Output Optoisolators Replacement Considerations

Check for official substitutes listed by Vishay for the SFH6712. Ensure replacement parts match the 8-DIP package and 5.3kV isolation rating. Verify that the new component supports similar data rates and propagation delays.
