Overview
The SFH609-2SM is a surface-mount optocoupler from Isocom Components, featuring a single phototransistor output in a DIP-6 package. It provides 2800 Vrms isolation voltage and supports a collector-emitter breakdown voltage of 70 V. The device operates with a maximum forward current of 60 mA and offers a typical current transfer ratio of 40%. Designed for industrial applications, it functions within a temperature range of -55°C to 100°C and includes UL recognition under File No. E91231.
Feature Summary
- Single-channel phototransistor output configuration
- Surface-mount packaging for automated assembly
- High isolation voltage capability
- Wide operating temperature range
Applications
- Industrial control systems
- Signal isolation in microprocessor interfaces
- Power supply feedback loops
- General-purpose digital signal coupling
Procurement Notes
Verify the specific suffix 'SM' confirms the surface-mount variant against the standard through-hole SFH609-2. Confirm RoHS compliance status and UL file number E91231 applicability for your region. Check lead form availability as approvals may exclude certain variants. Ensure the supplier provides official datasheets matching the Isocom Components specification.
Selection Notes
Select this component when surface-mount technology is required for single-channel isolation. Compare the 2800 Vrms isolation rating against system requirements. Consider the 40% CTR for logic level compatibility. Evaluate thermal management needs given the 100°C maximum junction temperature limit.
Part Context
This part belongs to the SFH609 series of optically coupled isolators. The series includes multiple variants with different output types and lead forms. The SFH609-2 specifically denotes the phototransistor output version. The SM suffix indicates the surface-mount package style, distinguishing it from standard DIP or CECC approved lead forms.
Replacement Considerations
Direct substitutes include other surface-mount phototransistor optocouplers with similar isolation ratings. Verify pinout compatibility before replacement. Cross-reference electrical parameters such as CTR and breakdown voltage. Consult manufacturer cross-reference guides for validated alternatives.
