4N29

Overview

The Everlight 4N29 is a single-channel transistor output optocoupler housed in a PDIP-6 package. It features a Photodarlington output configuration with an insulation voltage of 5000 Vrms. Key electrical parameters include a maximum collector-emitter voltage of 55 V, a forward current rating of 60 mA, and a typical forward voltage of 1.5 V. The device exhibits a minimum current transfer ratio of 100%, with rise and fall times of 25 us and 18 us respectively. It operates within a temperature range of -55 C to +100 C and has a power dissipation capacity of 200 mW.

Feature Summary

Provides high-voltage isolation between input and output circuits via optical transmission.
Utilizes a Photodarlington output structure for enhanced signal gain and sensitivity.
Designed for through-hole mounting to facilitate integration into standard circuit boards.

Applications

Signal isolation in industrial control systems
Interface circuits for microprocessors and logic devices
Switching applications in power supply units

Procurement Notes

Verify the specific manufacturer designation, as the 4N29 part number is utilized by multiple producers including Everlight. Confirm that the component matches the required PDIP-6 package and Photodarlington output type. Ensure compliance with relevant environmental standards such as RoHS if specified for your application. Check availability status, as supply constraints may affect procurement timelines.

Selection Notes

Select this component when high isolation voltage and moderate speed are required. The Photodarlington output offers higher current transfer efficiency compared to standard phototransistors. Consider the thermal limits and operating temperature range to ensure reliability in the intended environment. Verify pinout compatibility with existing PCB layouts before finalizing the design.

Part Context

The 4N29 is a widely recognized general-purpose optocoupler used for electrical isolation. It belongs to the family of transistor-output optoisolators designed for digital signal transmission. The device serves as a critical interface between low-voltage control circuits and higher-voltage load circuits, ensuring safety and noise immunity in electronic systems.

Replacement Considerations

Equivalent parts from other manufacturers may share the same pinout and electrical characteristics. Verify functional compatibility regarding current transfer ratio and switching speeds before substitution.
