SFH620A-1XSM

Overview

The SFH620A-1XSM is a single-channel optoisolator manufactured by Isocom Components 2004 LTD. It features an AC/DC input type and a transistor output configuration housed in a 4-SMD package. The device provides high isolation with a voltage rating of 5300Vrms and 7500V peak. Electrical characteristics include a maximum current transfer ratio of 125% at 10mA input, typical rise time of 4µs, and typical fall time of 3µs.

Feature Summary

• Provides galvanic isolation between input and output circuits using infrared technology.
• Supports both AC and DC input signal types for versatile interface applications.
• Utilizes a phototransistor output stage for digital signal transmission.

Applications

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

Procurement Notes

Verify the specific suffix 'XSM' against official manufacturer documentation to confirm surface-mount package dimensions and tape-and-reel specifications. Ensure that the AC/DC input capability aligns with the target circuit design requirements before finalizing procurement orders.

Selection Notes

Select this component when high isolation voltage and moderate speed are required for single-channel signal transmission. Consider the 4-SMD form factor for space-constrained PCB layouts. Evaluate the current transfer ratio limits to ensure adequate drive capability for the downstream load conditions.
