SFH618A-2SMT&R

Overview

The SFH618A-2SMT&R is a single-channel optoisolator manufactured by Isocom Components 2004 LTD. It features a transistor output and provides an isolation voltage of 5300Vrms. The device operates within a temperature range of -55°C to 100°C. Key electrical parameters include a maximum collector-emitter voltage of 30V, a peak forward current of 100mA, and a typical forward voltage of 1.25V. The unit supports a continuous output current of 50mA per channel with a minimum current transfer ratio of 63% at 10mA input.

Feature Summary

Provides high-voltage isolation between input and output circuits for signal transmission.
Utilizes a surface-mount package design suitable for automated assembly processes.
Delivers fast switching response times appropriate for digital signal applications.

Applications

General-purpose digital signal isolation in industrial control systems
Interface circuits connecting microcontrollers to power stages
Signal transmission across isolated boundaries in measurement equipment

Procurement Notes

Verify the specific manufacturer designation when sourcing this component, as distribution channels may list it under alternative branding or legacy part numbers. Confirm that the received units match the exact suffix requirements for your assembly process. Ensure compliance with relevant environmental standards before integration into final products.

Selection Notes

Choose this component when a single-channel transistor output is required for moderate-speed digital isolation. Consider the 5300Vrms isolation rating for safety-critical applications. Evaluate the 50mA output current capability against load requirements. Verify that the surface-mount footprint aligns with the printed circuit board layout constraints.

Part Context

This component belongs to the family of surface-mount optocouplers designed for compact electronic assemblies. It serves as a standard solution for galvanic isolation in modern electronics. The device replaces through-hole variants to support miniaturization trends in consumer and industrial hardware designs.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consult official manufacturer resources for direct replacements if this specific model becomes unavailable.
