SFH600-1G

Overview

The SFH600-1G is a single-channel through-hole optocoupler manufactured by Isocom Components. It features an NPN phototransistor output and utilizes a DIP-6 package for standard PCB mounting. The device provides electrical isolation with a maximum forward voltage of 1.65V and supports a maximum input current of 60 mA. Key performance metrics include a typical rise time of 3 µs and a fall time of 12 µs. The unit offers a minimum isolation voltage of 5300 Vrms, ensuring robust signal transmission between isolated circuits while maintaining high reliability in industrial applications.

Feature Summary

• Integrates an infrared emitting diode with an NPN phototransistor for efficient optical signal coupling.
• Provides high-voltage electrical isolation between input and output circuits to protect sensitive components.
• Designed for through-hole mounting in standard DIP-6 packages for reliable mechanical stability.

Applications

• Industrial control systems requiring galvanic isolation
• Signal interfacing between microcontrollers and high-voltage loads
• Power supply feedback loops for circuit protection

Procurement Notes

Verify the specific suffix 'G' against official Isocom documentation to confirm compliance with lead-free or RoHS standards, as suffixes may indicate material variations. Cross-reference the part number with authorized distributors to ensure authenticity and traceability. Confirm that the DIP-6 package dimensions match your PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a single-channel transistor output is required for moderate-speed signal isolation. The 5300 Vrms isolation rating suits applications with significant potential differences between domains. Consider the 3 µs rise time for timing-sensitive designs. Ensure the 60 mA maximum input current aligns with your driving circuit capabilities to prevent LED degradation.

Part Context

The SFH600 series represents a family of transistor-output optocouplers designed for general-purpose isolation. Variants within the series, such as SFH600-2 and SFH600-3, differ primarily in their Current Transfer Ratio (CTR) ranges. The SFH600-1G specifically targets applications requiring lower CTR characteristics compared to higher-gain variants, offering a balanced solution for standard digital isolation tasks.

Replacement Considerations

Publicly confirmed substitute part numbers for SFH600-1G are not available in the provided source data. Engineers should consult official manufacturer cross-reference lists or datasheets for verified equivalents. Generic replacements may vary in isolation voltage, CTR, or package dimensions, requiring careful validation.
