Overview
The 4N29G is a single-channel optocoupler manufactured by Isocom Components 2004 LTD. It features a Darlington output transistor configuration for high current transfer ratio capability. The device provides electrical isolation with a maximum insulation voltage of 7500 V and an RMS isolation rating of 5300 Vrms. It operates within a temperature range of -55°C to 100°C. Key electrical specifications include a typical forward voltage of 1.2V, a maximum DC forward current of 80 mA, and a maximum collector-emitter saturation voltage of 1V.
Feature Summary
- Darlington output structure for enhanced gain
- High isolation voltage ratings
- Wide operating temperature range
Applications
- General purpose signal isolation
- Microprocessor interface circuits
- Logic level shifting
Procurement Notes
Verify the specific manufacturer designation when sourcing, as Isocom Components 2004 LTD may supply devices under this part number or equivalent industry-standard designations. Confirm package type and pinout compatibility with existing PCB layouts. Ensure the supplier provides documentation confirming the Darlington output configuration and isolation voltage ratings match system requirements.
Selection Notes
Select this component when high current transfer ratio is required from a single channel. The Darlington output allows for driving higher load currents compared to standard phototransistor outputs. Consider the 7500 V insulation rating for applications requiring robust galvanic isolation between low-voltage control logic and higher-voltage power stages.
Part Context
Isocom Components 2004 LTD specializes in infrared optoelectronic devices, including optocouplers and optoswitches. The 4N29G belongs to their portfolio of general-purpose optocouplers designed for reliable signal transmission across isolated boundaries. The company has extensive experience in manufacturing these components for industrial and commercial electronics.
Replacement Considerations
The 4N29G is functionally compatible with the industry-standard 4N29 optocoupler. Verify pinout alignment and electrical parameter limits before substitution. Other Darlington-output optocouplers with similar isolation ratings may serve as alternatives if pin-compatible.
