SFH617A-1XSM

Overview

The SFH617A-1XSM is a single-channel transistor output optocoupler manufactured by Isocom Components 2004 LTD. It integrates an infrared emitting diode with an NPN silicon phototransistor in a surface-mount plastic package. The device provides electrical isolation between input and output circuits, rated at 4470Vrms isolation voltage. It is designed for applications requiring signal transmission across isolated boundaries while maintaining high reliability and safety standards.

Feature Summary

Integrates an infrared LED with an NPN silicon phototransistor for efficient optical coupling
Provides robust electrical isolation suitable for separating different circuit potentials
Utilizes a compact surface-mount plastic package for automated assembly

Applications

Logic-to-logic isolation in noisy environments
Line receiver circuits
Computer and peripheral device interfaces

Procurement Notes

Verify the specific suffix '1XSM' against official Isocom documentation to confirm pinout and isolation ratings. Ensure the component matches the required surface-mount footprint and that the 4470Vrms rating aligns with system safety requirements. Cross-reference datasheets for current transfer ratio specifications before integration.

Selection Notes

Select this component when a single-channel transistor output isolator is needed in a surface-mount form factor. Consider the 4470Vrms isolation capability for safety-critical designs. Evaluate the NPN phototransistor output characteristics against load requirements. Compare against other SFH617 variants if through-hole packaging or different output types are acceptable.

Part Context

This part belongs to the SFH617 series of optocouplers from Isocom Components 2004 LTD, which serves as a replacement source for legacy Siemens/Litronix devices. The series includes various channel counts and output types. The SFH617A-1XSM specifically denotes a single-channel variant in a surface-mount configuration, continuing the brand's focus on commercial optoelectronic replacements.
