Overview
The CEL PS2506-4 is a four-channel optoisolator featuring a GaAs infrared LED coupled to NPN silicon Darlington transistor arrays. It provides high isolation voltage of 5000 Vrms and supports AC input applications. The device operates with a maximum forward current of 80 mA and delivers a collector current up to 160 mA at an output voltage of 40 V. Power dissipation is rated at 160 mW, with an operating temperature range from -55°C to +100°C.
Feature Summary
- Four independent channels for multi-signal isolation
- High isolation voltage rating of 5000 Vrms
- Darlington output configuration for high gain
- Compatible with AC input signals
Applications
- Industrial control systems requiring signal isolation
- AC input detection circuits
- Multi-channel data transmission interfaces
- Power supply feedback loops
Procurement Notes
Verify the specific suffix (e.g., -A) against your design requirements, as it may indicate lead-free compliance or packaging variations. Confirm the package type matches your PCB footprint, typically 16-DIP or L SMT. Ensure the isolation voltage rating meets your safety standards. Check the datasheet for exact pinout configurations to avoid wiring errors during assembly.
Selection Notes
Select this component when multiple isolated channels are required in a single package. The Darlington output offers higher current transfer ratio compared to standard phototransistors. Verify that the 40 V output voltage and 160 mA collector current meet load requirements. Consider the 5000 Vrms isolation for high-voltage noise immunity in industrial environments.
Part Context
The PS2506-4 belongs to NEC/CEL's high isolation voltage photocoupler series. It shares architectural similarities with PS2506-1 and PS2506-2 but integrates four channels instead of one or two. This family is designed for robust performance in noisy electrical environments, utilizing GaAs LEDs for efficient light emission and silicon Darlington arrays for signal amplification.
Replacement Considerations
Check for direct equivalents like PS2506L-4 for alternative packaging. Verify pin compatibility before substituting with other four-channel optocouplers. Ensure replacement parts maintain the 5000 Vrms isolation rating and Darlington output characteristics.
