4N29FSMT&R

Overview

The 4N29FSMT&R is a surface-mount optocoupler manufactured by Isocom Components 2004 LTD. It features a single channel with a Darlington transistor output configuration housed in a 6-pin Surface Mount DIP package. Key electrical specifications include a maximum forward voltage of 1.65V, a typical rise time of 2µs, and a typical fall time of 11µs. The device supports a maximum input current of 50 mA and provides an isolation voltage of 5.3 kVrms.

Feature Summary

Provides electrical isolation between input and output circuits using a Darlington phototransistor output stage.

Applications

Electrical isolation in electronic circuits to prevent noise interference.

Procurement Notes

Verify the specific suffix 'FSMT&R' against official manufacturer documentation to confirm the exact tape-and-reel packaging and pin configuration. Ensure compatibility with surface-mount assembly processes. Cross-reference the part number with the latest Isocom Components datasheets to validate current manufacturing status and any potential obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component for applications requiring high gain due to the Darlington output structure. It is suitable for designs needing robust galvanic isolation up to 5.3 kVrms. Consider the surface-mount form factor for compact PCB layouts. Verify that the input current requirements align with the 50 mA maximum rating and that the switching speed meets the system's timing constraints.

Part Context

This component belongs to the 4N29 series of optoisolators, which are widely used for signal transmission across isolated boundaries. The SMT variant facilitates automated assembly. It serves as a bridge for control signals in environments with high voltage differences or electromagnetic interference, ensuring circuit protection and signal integrity.
