SFH617A-3SMT&R

Overview

The SFH617A-3SMT&R is a single-channel surface-mount optocoupler manufactured by Isocom Components. It features a phototransistor output and utilizes a 4-pin PDIP package. The device provides galvanic isolation with a maximum isolation voltage of 5.3 kVrms. Key electrical parameters include a maximum forward voltage of 1.65V, a typical rise time of 2µs, and a typical fall time of 14µs. It supports a maximum input current of 60mA and offers a minimum current transfer ratio of 100% with a maximum of 200%.

Feature Summary

Provides high-voltage galvanic isolation between input and output circuits.
Integrates an infrared emitting diode with a silicon phototransistor for signal transmission.
Designed for surface-mount technology applications requiring compact packaging.

Applications

Industrial control systems requiring signal isolation.
Communication equipment interface circuits.
Power supply feedback loops.

Procurement Notes

Verify the specific suffix 'SMT&R' to confirm surface-mount tape-and-reel packaging configuration. Ensure compatibility with standard reflow soldering profiles for the 4-pin DIP form factor. Cross-reference manufacturer datasheets for precise handling and storage sensitivity classifications before integration into production workflows.

Selection Notes

Select this component when a single-channel transistor-output isolator is required in a surface-mount footprint. Consider the 5.3 kVrms isolation rating for safety-critical applications. Evaluate the 100% to 200% current transfer ratio range against load requirements. Confirm that the 4-pin layout fits the target PCB design constraints compared to alternative pin counts.

Part Context

This part belongs to the SFH series of optocouplers from Isocom Components. It represents a transition from through-hole to surface-mount implementations while maintaining similar electrical characteristics to other devices in the family. The component serves as a bridge for digital signal isolation in modern electronic assemblies.
