Overview
The SFH600-3SMT&R is a surface-mount single-channel optocoupler manufactured by Isocom Components. It features an NPN phototransistor output and operates with a DC input current type. The device provides high isolation capability with a rated voltage of 5300 Vrms. Key electrical parameters include a maximum forward voltage of 1.65V, a typical rise time of 2µs, and a typical fall time of 11µs. The unit supports a maximum input current of 60 mA and offers a minimum current transfer ratio of 200% with a maximum of 400%. It is housed in a 6-pin DIP package.
Feature Summary
- Provides galvanic isolation between input and output circuits using infrared light transmission.
- Features an NPN phototransistor output stage for digital signal switching applications.
- Designed for surface-mount technology (SMT) assembly to facilitate automated PCB placement.
Applications
- Industrial control systems requiring signal isolation
- Power supply units for feedback loop isolation
- Data communication interfaces needing noise immunity
Procurement Notes
Verify the specific suffix 'SMT&R' confirms the reel packaging format required for your assembly line equipment. Confirm that the 6-pin DIP footprint matches your board layout exactly. Ensure the manufacturer designation on the datasheet aligns with Isocom Components rather than the original design source, as component sourcing may vary by region.
Selection Notes
Select this component when a surface-mount solution is required for single-channel isolation with high current transfer ratios. Compare the 5300 Vrms isolation rating against system safety requirements. Evaluate the 2µs rise time against the maximum switching frequency needed in the target circuit to ensure adequate response speed without distortion.
Part Context
This part belongs to the SFH600 series of optocouplers, which are widely recognized for their reliability in industrial environments. Isocom Components sources these devices to provide alternatives to discontinued or hard-to-find semiconductor parts. The series is characterized by robust performance in standard DIP form factors adapted for modern SMT processes.
Replacement Considerations
Direct replacements must match the 6-pin DIP SMT package and NPN phototransistor output configuration. Verify that substitute components meet the 5300 Vrms isolation requirement and similar CTR ranges. Check pinout compatibility to ensure direct interchangeability without PCB redesign.
