Overview
The Everlight 4N25-V is a single-channel optocoupler featuring an infrared LED emitter and an NPN phototransistor output with a base terminal. It provides electrical isolation of 5000 Vrms between input and output circuits. The device operates within a temperature range of -55°C to +110°C and utilizes a 6-pin DIP package. Key electrical parameters include a forward current of 60 mA, collector-emitter voltage of 80 V, and typical current transfer ratio of 20%.
Feature Summary
- Integrates an infrared emitting diode with an NPN phototransistor for signal transmission
- Provides high-voltage electrical isolation via internal optical coupling mechanism
- Includes a dedicated base pin on the phototransistor for sensitivity control
Applications
- Industrial control systems requiring circuit isolation
- Signal switching in low-frequency digital logic interfaces
- Power supply feedback loops for voltage regulation
Procurement Notes
Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm RoHS compliance status and lead-free certification through supplier documentation. Ensure the part number suffix matches the exact variant required for your design specifications before finalizing orders.
Selection Notes
Select this component when standard transistor output isolation is sufficient for the application. Consider the base pin availability if external biasing or speed adjustment is necessary. Verify that the 5000 Vrms isolation rating meets the safety requirements of the target system environment.
Part Context
This component belongs to the general-purpose optocoupler family produced by Everlight Electronics. It shares the standard 4N25 pinout configuration but may differ in specific manufacturing batches or regional compliance certifications. It serves as a fundamental building block for galvanic isolation in electronic circuits.
Replacement Considerations
Direct substitutes include other 4N25 variants from different manufacturers such as Vishay or ON Semiconductor. Ensure replacement parts maintain the same DIP-6 package and electrical characteristics for pin-compatible integration.
