Overview
The Everlight 4N29M is a single-channel transistor output optocoupler featuring an internal photodarlington structure housed in a PDIP-6 package. It provides high isolation voltage of 5000 Vrms between input and output circuits. The device supports a maximum forward current of 60 mA with a typical forward voltage of 1.2 V. The collector-emitter breakdown voltage is rated at 55 V, while the reverse voltage capability is 6 V. Power dissipation is limited to 200 mW. Operating temperatures range from -55°C to +100°C. Rise and fall times are specified at 25 µs and 18 µs respectively.
Feature Summary
- Photodarlington output configuration for high sensitivity
- High insulation voltage rating for safety isolation
- Through-hole mounting in compact dual-in-line package
Applications
- Power supply regulators
- Digital logic inputs
- Microprocessor inputs
Procurement Notes
Verify component authenticity through official manufacturer channels or authorized distributors. Confirm RoHS compliance status and specific UL/VDE approval numbers required for your region. Check datasheet revisions for parameter updates. Ensure packaging type matches assembly requirements. Validate temperature ratings against operational environment constraints before procurement.
Selection Notes
Select this component when high gain is required due to the photodarlington output stage compared to standard phototransistors. Consider the slower switching speed inherent to darlington structures versus single transistors. Verify isolation voltage requirements meet system safety standards. Evaluate thermal management needs within the specified power dissipation limits. Compare CTR specifications against drive circuit capabilities.
Part Context
The 4N29M belongs to the 4N2X series of optocouplers manufactured by Everlight Electronics. This series includes variants like 4N25, 4N26, and 4N27, sharing similar DIP-6 packaging and isolation characteristics. The 4N29M specifically utilizes a photodarlington output for enhanced sensitivity. It is part of a long-standing family of general-purpose optocouplers widely used in industrial and consumer electronics for signal isolation.
Replacement Considerations
Equivalent parts include Fairchild Semiconductor 4N29M and other generic 4N29 variants. Verify pinout compatibility and electrical parameters such as CTR and isolation voltage. Check for identical package dimensions and mounting styles. Ensure replacement meets same regulatory approvals if applicable.
