SFH620A-2XSM

Overview

The SFH620A-2XSM is a single-channel optocoupler manufactured by Isocom Components 2004 LTD. It features an AC input configuration utilizing inverse parallel infrared LEDs and an NPN silicon phototransistor output. The device provides high isolation with a minimum isolation voltage of 5300 VRMS and a peak withstand voltage of 7500 VPK. Electrical characteristics include a collector-emitter saturation voltage (VCESAT) of 0.4 V at 10 mA forward current and 2.5 mA collector current. It is housed in a DIP-4 package.

Feature Summary

• AC input capability via inverse parallel infrared LED structure
• High-voltage electrical isolation between input and output circuits
• NPN silicon phototransistor output for digital signal switching

Applications

• Logic-to-logic isolation in noisy environments
• Line receiver circuits
• Digital control of motors and servo machines

Procurement Notes

Verify the specific suffix '2XSM' against official Isocom documentation to confirm pinout, packaging style, and compliance certifications. Ensure the component matches the required AC input specification and isolation voltage ratings for the target application circuit design.

Selection Notes

Select this component when AC signal isolation is required without external rectification. The inverse parallel LED design simplifies circuit topology. Verify that the NPN transistor output current transfer ratio meets the load requirements and that the DIP-4 package fits the PCB layout constraints.

Part Context

This part belongs to the SFH620A series, which are AC-input optocouplers designed as industry-standard replacements. Isocom Components specializes in providing alternatives to discontinued or hard-to-find optocouplers from other manufacturers, maintaining compatibility with established designs.

Replacement Considerations

Parametric equivalents may be available. Verify pin compatibility and electrical parameters such as CTR and isolation voltage before substitution.
