SFH600-4XSMT&R

Overview

The SFH600-4XSMT&R is a surface-mount single-channel optocoupler manufactured by Isocom Components. It features an NPN phototransistor output and utilizes a DIP-style SMD package with six pins. The device provides high isolation capability of 5300 Vrms between input and output circuits. 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 current transfer ratio ranges from a minimum of 200% to a maximum of 400%, supporting a maximum collector current of 50 mA.

Feature Summary

• NPN phototransistor output configuration for digital signal isolation
• High insulation voltage rating of 5300 Vrms for safety compliance
• Surface-mount technology compatible with automated assembly processes
• Fast switching characteristics suitable for general-purpose applications

Applications

• Industrial control systems requiring galvanic isolation
• Power supply units for feedback loop isolation
• Microprocessor interface circuits
• Signal transmission in noisy environments

Procurement Notes

Verify the specific suffix 'XSMT&R' against official Isocom documentation to confirm surface-mount tape-and-reel packaging specifications. Ensure the component matches the required NPN output type and 6-pin DIP footprint dimensions for your PCB layout. Cross-reference the CTR range (200%-400%) with circuit design requirements to guarantee proper signal integrity during operation.

Selection Notes

Select this component when a surface-mount solution is required for single-channel isolation with moderate speed requirements. The NPN output is suitable for standard logic interfacing. Consider the 5300 Vrms isolation rating for applications demanding robust safety barriers. Verify that the 6-pin package fits within the available board space constraints compared to smaller 4-pin alternatives.

Part Context

This part belongs to the SFH600 series of optocouplers produced by Isocom Components. The series is designed as a replacement for industry-standard components, offering comparable performance with flexible manufacturing options. Isocom specializes in providing alternative sources for discontinued or hard-to-find optoelectronic devices, ensuring supply chain continuity for critical electronic assemblies.

Replacement Considerations

Direct cross-reference data for SFH600-4XSMT&R substitutes is not explicitly provided in the source material. However, the SFH600 series generally corresponds to standard NPN phototransistor optocouplers. Users should verify pinout compatibility and electrical parameters against original designs before substituting with other manufacturers' equivalents.
