Overview
The CEL PS2502-1-M-A is a single-channel transistor output optocoupler featuring a Darlington phototransistor output. It provides 5000Vrms isolation voltage between input and output circuits. The device supports a maximum forward current of 80 mA and a collector current of 50 mA. Key electrical parameters include a typical current transfer ratio of 200% at 5 mA, a maximum collector-emitter saturation voltage of 300 mV, and a power dissipation rating of 150 mW. It operates within a temperature range of -55°C to +100°C and is housed in a 4-DIP package.
Feature Summary
- Provides high-voltage electrical isolation for signal transmission
- Utilizes Darlington output configuration for high gain
- Designed for robust performance across wide temperature ranges
Applications
- AC input sensing circuits
- Solid-state relay drivers
- Microcontroller interface isolation
Procurement Notes
Verify component authenticity through authorized channels due to discontinued status. Confirm RoHS compliance details as documentation may vary by production batch. Ensure the specific suffix matches required pinout and insulation standards. Cross-reference datasheet revisions to validate electrical characteristics against current design requirements before integration.
Selection Notes
Select this component when high current transfer ratio is required from a single channel. The Darlington output offers higher sensitivity compared to standard phototransistor variants. Consider the 4-DIP package constraints for PCB layout. Verify that the 50 mA collector current meets load requirements. Check isolation voltage ratings against system safety standards.
Part Context
This part belongs to the CEL PS2502 series of optocouplers. The series includes variants with different channel counts and output types. The PS2502-1-M-A specifically denotes a single-channel unit with Darlington output. It is part of California Eastern Laboratories' portfolio of isolation components.
Replacement Considerations
PS2502L-1-A is a documented substitute within the same manufacturer family. Verify pin compatibility and electrical parameter alignment before substitution.
