Overview
The PS2503L-1-L-A is a single-channel transistor output optocoupler manufactured by CEL. It integrates an AlGaAs LED and an NPN silicon phototransistor within a surface-mount DIP-4 package. Key electrical specifications include a maximum collector-emitter voltage of 40 V, a maximum collector current of 30 mA, and a forward current of 80 mA. The device offers an isolation voltage of 5000 Vrms and operates within a temperature range of -55°C to +100°C.
Feature Summary
- Provides high-speed switching capabilities for signal transmission
- Ensures electrical isolation between input and output circuits
- Features low collector-emitter saturation voltage for efficient operation
Applications
- General-purpose signal isolation in industrial control systems
- Interface circuits for microprocessors and logic devices
- Power supply feedback loops requiring galvanic isolation
Procurement Notes
Verify the specific suffix 'L-A' against official CEL documentation to confirm pinout and packaging details. Confirm RoHS compliance status through the manufacturer's latest datasheet or certification documents before integration into designs.
Selection Notes
Select this component when a compact surface-mount solution with moderate speed and high isolation voltage is required. Ensure the circuit design accommodates the specified 80 mA forward current limit and 40 V collector-emitter voltage rating for reliable long-term performance.
Part Context
This part belongs to the PS2503L series of optocouplers from CEL. The series is designed for general-purpose applications requiring reliable optical isolation. The 'L' designation typically indicates a lead-free and halogen-free compliant package variant suitable for modern manufacturing processes.
Replacement Considerations
Direct substitutes may include other single-channel NPN phototransistor optocouplers with similar DIP-4 SMD packages and 5000 Vrms isolation ratings. Verify pin compatibility and electrical parameters such as CTR and propagation delay before substitution.
