Overview
The PS2505L-4-E3-A is a four-channel transistor output optocoupler manufactured by CEL. It features an NPN phototransistor output with a maximum collector-emitter voltage of 80 V and a maximum collector current of 50 mA. The device provides 5000 Vrms isolation voltage between input and output channels. It operates within a temperature range of -55°C to +100°C and is housed in a 16-SMD,鸥翼 (gull-wing) surface-mount package.
Feature Summary
- Four independent channels for multi-signal isolation
- High insulation voltage rating for safety separation
- NPN phototransistor output configuration
- Surface-mount packaging for automated assembly
Applications
- Industrial control systems requiring multi-channel signal isolation
- Power supply feedback loops
- Communication interface isolation
- Microcontroller I/O expansion with galvanic isolation
Procurement Notes
Verify component authenticity through authorized CEL distributors or Renesas Electronics channels. Confirm RoHS compliance status as indicated in official datasheets. Check for obsolescence notices or lifecycle changes before finalizing procurement plans. Ensure storage conditions meet manufacturer specifications to maintain performance integrity.
Selection Notes
Select this component when four isolated channels are required in a compact surface-mount form factor. Consider the 5000 Vrms isolation rating for high-voltage noise environments. Verify that the NPN output type matches the receiving circuit requirements. Ensure the operating temperature range suits the application environment.
Part Context
This part belongs to the PS2505L series of optocouplers from CEL, now under Renesas Electronics. The series offers various channel configurations including single, dual, and quad options. The PS2505L-4 variant specifically provides four isolated channels in a single package, suitable for applications needing multiple isolation barriers without increasing board space significantly.
Replacement Considerations
PS2505L-4-E4-A may serve as a direct replacement if available. Verify pinout compatibility and electrical parameters against original design requirements before substitution.
