SFH617A-2XSMT&R

Overview

The SFH617A-2XSMT&R is a single-channel optocoupler manufactured by Isocom Components. It features a surface-mount DIP package with four pins. The device utilizes an infrared LED input and an NPN silicon phototransistor output. Key electrical specifications include a maximum forward voltage of 1.65V, a maximum input current of 50 mA, and an isolation voltage of 4470 Vrms. The typical rise time is 2µs, while the typical fall time is 11µs. The minimum current transfer ratio is 63%.

Feature Summary

Integrates an infrared light emitting diode with an NPN silicon phototransistor for signal transmission
Provides high-voltage isolation between input and output circuits via dielectric barrier
Designed for surface-mount assembly to facilitate automated PCB placement

Applications

Industrial automation control systems
Process automation monitoring circuits
High-power module interface isolation

Procurement Notes

Verify the specific suffix 'SMT&R' against official manufacturer documentation to confirm the exact reel packaging configuration and tape-and-reel specifications. Ensure the component matches the required surface-mount footprint and pin alignment for the target application board design before finalizing procurement orders.

Selection Notes

Select this component when a compact, surface-mount solution is required for galvanic isolation in low-to-medium speed digital signaling applications. Consider the 4-pin form factor and specified isolation voltage ratings relative to system safety requirements. Evaluate the current transfer ratio and switching speeds against the timing constraints of the driven load circuitry.

Part Context

This part belongs to the SFH617 series of optocouplers from Isocom Components. The series typically offers transistor outputs for general-purpose isolation tasks. The SMT variant specifically addresses modern manufacturing needs for reduced board space and improved production efficiency compared to through-hole alternatives.
