Overview
The PS2505L-1-F3-A is a single-channel transistor output optocoupler from the NEPOC series, manufactured by CEL. It features an NPN phototransistor output and supports AC/DC input signals. Key electrical parameters include a maximum collector-emitter voltage of 80 V, a maximum collector current of 50 mA, and a forward current rating of 80 mA. The device provides high isolation with a rated insulation voltage of 5000 Vrms. It operates within a temperature range of -55°C to +100°C and is housed in a surface-mount SMD-PDIP-4 package.
Feature Summary
- Supports AC input response for direct connection to AC power lines without external rectification
- High common mode transient immunity for reliable operation in noisy environments
- Surface mount packaging designed for automated assembly processes
Applications
- AC mains detection circuits
- Solid state relay driver interfaces
- Microcontroller input isolation for AC loads
Procurement Notes
Verify component authenticity through authorized CEL distributors or certified suppliers. Confirm RoHS compliance status as indicated on official datasheets. Check for obsolescence notices, as lifecycle status may affect long-term availability. Ensure storage conditions meet manufacturer specifications to prevent moisture sensitivity issues prior to reflow soldering.
Selection Notes
Select this component when AC input detection is required alongside galvanic isolation. Compare CTR ranges against specific drive requirements. Verify package compatibility with existing PCB footprints. Consider thermal dissipation limits if operating near maximum junction temperatures. Evaluate alternative channels if multiple isolation points are needed.
Part Context
This part belongs to the PS2505L family of high-isolation voltage optocouplers. It shares architectural similarities with other members like the PS2505L-2 but differs in channel count and pin configuration. The F3 suffix typically denotes specific tape-and-reel packaging variations compared to tube-packed equivalents.
Replacement Considerations
PS2505L-1-F3 is a functional equivalent from NEC/Renesas. PS2505L-1-A is a related variant with different packaging. Verify pinout compatibility before substitution.
