SFH617A-3XSM

Overview

The SFH617A-3XSM is a single-channel optocoupler featuring an infrared LED and NPN silicon phototransistor. It utilizes surface-mount packaging with four pins. The device provides galvanic isolation with a maximum isolation voltage of 4470Vrms. Key electrical parameters include a typical rise time of 2μs, a typical fall time of 14μs, and a minimum current transfer ratio of 100%. It operates within a temperature range of -55°C to 110°C.

Feature Summary

Provides high-voltage galvanic isolation between input and output circuits
Integrates an infrared emitter with an NPN silicon phototransistor for signal transmission
Designed for surface-mount assembly in compact electronic systems

Applications

Logic-to-logic isolation in noisy environments
Line receiver applications
Programmable current level sensing
Digital control of motors and servo machines

Procurement Notes

Verify the specific suffix '3XSM' against official Isocom documentation to confirm surface-mount configuration and pinout compatibility. Ensure that the 4470Vrms isolation rating meets the safety requirements of the target application. Cross-reference the package dimensions with PCB footprint specifications before finalizing procurement orders.

Selection Notes

Select this component when surface-mount technology is required for single-channel isolation. Consider the 2μs rise time and 14μs fall time for signal integrity in moderate-speed digital interfaces. Evaluate the 100% minimum current transfer ratio to ensure adequate output drive capability under varying temperature conditions from -55°C to 110°C.
