Overview
The Everlight 4N27M is a single-channel transistor output optocoupler housed in a 6-pin DIP package. It features an NPN phototransistor with a base terminal for improved switching performance. Key electrical parameters include a maximum collector-emitter voltage of 80 V, a minimum current transfer ratio of 10%, and a forward voltage of 1.5 V at 60 mA forward current. The device offers 5000 Vrms isolation voltage and operates within a temperature range of -55°C to +110°C.
Feature Summary
- Integrated base terminal on the phototransistor to enhance switching speed and reduce storage time
- High isolation voltage capability between input LED and output transistor
- RoHS compliant construction with lead-free packaging
Applications
- Industrial control systems requiring signal isolation
- Computer peripheral interface circuits
- Power supply feedback loops
Procurement Notes
Verify component authenticity through official manufacturer channels or authorized distributors. Confirm RoHS compliance status and specific lot traceability requirements before procurement. Ensure the selected variant matches the required DIP-6 package configuration and thermal specifications for the intended application environment.
Selection Notes
Select this component when base-driven switching speed is critical compared to standard phototransistors. Verify that the 80 V collector-emitter voltage rating exceeds the circuit's peak operating voltage. Ensure the 10% minimum CTR aligns with the load requirements and input drive capabilities of the controlling logic.
Part Context
This part belongs to the 4N2X series of transistor output optocouplers from Everlight Electronics. It shares the same physical footprint and basic isolation characteristics as variants like the 4N25, 4N26, and 4N28, but distinguishes itself by including a base connection on the output transistor for faster response times.
Replacement Considerations
Direct pin-compatible substitutes within the same family include the 4N25, 4N26, and 4N28. Verify that the replacement part maintains the necessary current transfer ratio and switching speed requirements for the specific circuit design.
