SFH620A-2G

Overview

The SFH620A-2G is a single-channel optically coupled isolator manufactured by Isocom Components 2004 LTD. It features an AC input configuration utilizing inverse parallel infrared light emitting diodes paired with an NPN silicon phototransistor output. The device provides electrical isolation with a maximum output voltage rating of 70V and a dielectric strength of 5300Vrms. It is housed in a standard 4-pin DIP package with a pin spacing of 0.400 inches, designed for through-hole mounting.

Feature Summary

AC input capability via inverse parallel infrared LEDs
NPN silicon phototransistor output stage
High voltage isolation barrier rated at 5300Vrms

Applications

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

Procurement Notes

Verify the manufacturer designation as Isocom Components 2004 LTD when sourcing this component. Confirm the package type is 4-DIP (0.400 inch) to ensure mechanical compatibility with existing PCB layouts. Check that the specific suffix matches the required AC input variant. Ensure compliance with relevant safety certifications such as UL or VDE if required by the end application standards.

Selection Notes

Select this component for applications requiring AC signal input isolation. The inverse parallel LED structure allows operation with alternating current inputs without external rectification. The NPN phototransistor output is suitable for digital switching applications. Consider the 5300Vrms isolation rating for high-voltage separation requirements between input and output circuits.
