Overview
The CEL PS2506-1-A is a single-channel transistor output optocoupler housed in a 4-pin DIP package. It features an NPN Photodarlington output with a minimum current transfer ratio of 200%. The device supports a maximum forward current of 80 mA and a collector-emitter voltage of 40 V, with a peak collector current capability of 200 mA. Electrical isolation is rated at 5000 Vrms. Operating temperatures range from -55°C to +100°C, with a power dissipation limit of 200 mW.
Feature Summary
- High isolation voltage rating for AC input applications
- NPN Photodarlington output configuration for high gain
- Through-hole mounting in standard DIP-4 package
Applications
- AC input detection circuits
- Industrial control signal isolation
- Power supply feedback loops
Procurement Notes
Verify the manufacturer designation carefully, as sources list both Renesas Electronics and CEL for this part number. Confirm the specific datasheet version matches the required electrical characteristics, particularly the Current Transfer Ratio which varies between 200% and 2000% across different documentation sets. Ensure the package type and pinout align with your PCB footprint requirements before finalizing procurement.
Selection Notes
Select this component when high isolation voltage is required for AC input sensing. The Photodarlington output provides higher sensitivity compared to standard phototransistors. Verify that the 80 mA forward current drive capability fits within your circuit's power budget. Consider the 100 us switching speed if used in high-frequency digital isolation applications.
Part Context
This part belongs to the PS2506 series of multi-photocouplers designed for high isolation voltage applications. The series includes variants with different channel counts and output types. The PS2506-1-A specifically denotes the single-channel variant with Darlington output configuration.
Replacement Considerations
PS2506-1 is a related variant within the same family. PS2566L2-1-A offers similar isolation but with a typical CTR of 2000%. Verify pin compatibility and electrical parameters before substitution.
