4N29FG

Overview

The 4N29FG is a single-channel optocoupler manufactured by Isocom Components 2004 LTD. It features a Darlington transistor output configuration housed in a standard 6-pin DIP package. The device provides an isolation voltage rating of 5300Vrms, ensuring robust electrical separation between input and output circuits. Key electrical specifications include a collector-emitter saturation voltage of 1.2V and a collector current capability of 60mA. The unit offers a high current transfer ratio of 100% and operates with a propagation delay of 5 microseconds for both turn-on and turn-off transitions.

Feature Summary

Darlington compound transistor output structure for high gain
High isolation voltage rating for safety-critical applications
Standard 6-pin dual in-line package for through-hole mounting

Applications

Industrial control systems requiring galvanic isolation
Solid-state relay driver circuits
Microprocessor interface isolation

Procurement Notes

Verify the specific suffix FG against official Isocom Components documentation to confirm the Darlington output variant and pinout configuration. Ensure that the 6-DIP package dimensions align with the target PCB footprint. Cross-reference the 5300Vrms isolation rating with system safety requirements before finalizing component selection for production.

Selection Notes

Select this component when high current gain is required from a low input drive signal. The Darlington output architecture supports higher load currents compared to standard phototransistor variants. Confirm that the 60mA collector current limit meets the downstream circuit demands. Evaluate the 5 microsecond switching speed suitability for the intended signal frequency.

Part Context

This part belongs to the family of single-channel optoisolators designed for general-purpose isolation tasks. The 4N29 series is widely recognized in industrial electronics for its reliability and standardized packaging. The FG designation specifies the particular output type and mechanical form factor within the manufacturer's portfolio.
