Overview
The CEL PS2502L-1-E3-A is a single-channel optocoupler featuring a GaAs infrared LED coupled to a Darlington transistor output. It provides 5000Vrms isolation voltage and operates within a temperature range of -55°C to 100°C. The device offers a nominal current transfer ratio of 200% at 1mA input current, with a minimum collector-emitter breakdown voltage of 40V. Designed for high-density mounting, it utilizes an 8-pin DIP package.
Feature Summary
- High-density mounting design suitable for compact circuit layouts
- Darlington output configuration providing high current gain
- Robust electrical isolation between input and output circuits
Applications
- Industrial control systems requiring signal isolation
- Power supply feedback loops
- Solid-state relay driver circuits
Procurement Notes
Verify component authenticity through authorized CEL or Renesas distributors. Confirm the specific suffix matches the required lead-free and RoHS compliance standards. Check manufacturing status as this part may be obsolete; validate availability with suppliers before finalizing procurement plans.
Selection Notes
Select this component when high current transfer ratio is needed without external amplification. Ensure the 5000Vrms isolation rating meets system safety requirements. Verify that the 40V collector-emitter breakdown voltage is sufficient for the load application. Consider thermal management for operation near the 100°C maximum limit.
Part Context
This device belongs to the NEPOC series from California Eastern Labs (CEL), now part of Renesas. It is part of the PS2502 family, which includes variants with different channel counts and output types. The PS2502L-1 variant specifically denotes a single-channel unit with enhanced performance characteristics compared to standard versions.
Replacement Considerations
Direct substitutes include PS2502-1-E3-A and PS2502L-1-E3-L-A. Verify pinout compatibility and electrical parameters such as CTR and isolation voltage before substitution. Cross-reference with Renesas datasheets for updated specifications.
