Overview
The CEL PS2561DL1-1Y-F3-L-A is a single-channel transistor output optocoupler housed in a 4-pin DIP package. It features an NPN phototransistor output with a maximum collector-emitter voltage of 80 V and a peak forward current rating of 40 mA. The device provides high isolation capability, rated at 5000 Vrms. Key electrical parameters include a minimum current transfer ratio of 50% and a maximum of 400%, with a typical forward voltage of 1.4 V. It operates within a temperature range of -55°C to +110°C and has a power dissipation limit of 150 mW.
Feature Summary
- Provides galvanic isolation between input and output circuits using an infrared LED and NPN phototransistor pair.
- Offers high dielectric strength with a 5000 Vrms insulation voltage rating for robust noise immunity.
- Designed for surface-mount installation in a compact 4-pin gull-wing DIP configuration.
Applications
- Industrial control systems requiring signal isolation
- Power supply feedback loops
- Microcontroller interface circuits
Procurement Notes
Verify the specific suffix 'L' against manufacturer documentation to confirm lead-free compliance or specific tape-and-reel packaging requirements. Ensure the ordering part number matches the exact pinout and isolation ratings required by the design specifications before finalizing procurement.
Selection Notes
Select this component when a surface-mount solution is required for single-channel isolation with high CTR variability. Compare the 50-400% CTR range against circuit gain requirements. Verify that the 80 V collector-emitter voltage and 50 mA collector current limits accommodate the load conditions in the target application environment.
Part Context
This part belongs to the PS2561DL series of transistor output optocouplers manufactured by Renesas Electronics under the CEL brand. The series is characterized by its small 4-pin form factor and high isolation voltage, making it suitable for space-constrained designs needing reliable signal transmission across isolated boundaries.
Replacement Considerations
Direct substitutes include the PS2561DL1-1Y-F3-A and PS2561DL1-1Y-Q. Verify pin compatibility and electrical parameter equivalence, particularly the current transfer ratio and isolation voltage, before substituting.
