Overview
The IS604SM is a single-channel AC input-transistor output optocoupler manufactured by Isocom Components. It provides 5300Vrms isolation voltage and operates within a temperature range of -55°C to 100°C. The device features a minimum current transfer ratio of 50% at 10mA, with a maximum forward current of 0.1A and typical forward voltage of 1.5V. Collector-emitter breakdown voltage is at least 30V, and maximum dark power is 50nA. It is housed in a 6-pin surface mount plastic package and complies with RoHS standards.
Feature Summary
- AC input capability for direct mains or AC signal interfacing
- High isolation voltage rating of 5300Vrms
- Transistor output configuration with open-collector structure
Applications
- Solid-state relay driver circuits
- Mains-powered equipment control interfaces
- Industrial automation signal isolation
Procurement Notes
Verify the specific manufacturer designation, as Isocom Components often distributes rebranded parts from other foundries. Confirm the package type matches the required PCB footprint and ensure the AC input specification aligns with the application's voltage requirements. Check for RoHS compliance documentation if environmental regulations apply.
Selection Notes
Select this component when high isolation voltage and AC input compatibility are required in a compact surface-mount form factor. Consider the 50% minimum CTR for driving subsequent logic stages. Evaluate thermal management capabilities given the 100°C maximum operating temperature limit.
Part Context
Isocom Components specializes in providing alternative sources for standard optocouplers, including those discontinued by original manufacturers. The IS604SM belongs to their surface-mount transistor output series, designed to replace legacy DIP packages with modern SMD solutions while maintaining electrical equivalence.
Replacement Considerations
Cross-reference with equivalent AC-input transistor output optocouplers offering similar 5300Vrms isolation. Verify pinout compatibility and current transfer ratio specifications before substitution.
