Overview
The SFH600-1SM is a single-channel transistor output optocoupler manufactured by Isocom Components. It features a DIP-6 surface mount package and provides 5300V isolation voltage. The device utilizes a phototransistor output with a minimum collector-emitter breakdown voltage of 70V. Key electrical parameters include a maximum forward current of 0.06A, a typical current transfer ratio of 40%, and a maximum dark current of 35nA. It operates within a temperature range of -55°C to 100°C.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits
- Utilizes a phototransistor for signal transmission
- Designed for surface mount assembly in compact layouts
Applications
- Industrial control systems requiring galvanic isolation
- Signal interfacing in automated machinery
- Power supply feedback loops
Procurement Notes
Verify the specific suffix 'SM' confirms the surface mount package variant against official datasheets. Ensure compatibility with RoHS compliance standards if required by the target application. Cross-reference the manufacturer part number with authorized distributors to confirm availability and authenticity before procurement.
Selection Notes
Select this component when a surface mount solution is required for high-isolation applications. The 5300V rating suits industrial environments. Consider the 40% CTR and 70V Vceo for circuit design margins. Verify that the DIP-6 footprint matches the PCB layout constraints.
Part Context
This part belongs to the SFH600 series of optocouplers, which are widely used for general-purpose isolation. The SFH600-1SM specifically denotes the surface mount version of the standard through-hole SFH600-1. It shares core electrical characteristics with the series while offering different packaging for automated assembly.
Replacement Considerations
Direct replacements may include other SFH600 series variants with compatible pinouts. Verify that substitute components match the 5300V isolation and 70V breakdown voltage requirements. Check package dimensions for DIP-6 compatibility.
