Overview
The CEL PS2505L-2-E3-A is a dual-channel transistor output optocoupler designed for high-isolation applications. It features an NPN phototransistor output with a maximum collector-emitter voltage of 80 V and a collector current of 50 mA. The device provides 5000 Vrms insulation voltage between input and output. Key electrical parameters include a forward current of 80 mA, a typical forward voltage of 1.17 V, and a maximum collector-emitter saturation voltage of 300 mV. It operates within a temperature range of -55°C to +100°C and is housed in an 8-SMD package.
Feature Summary
- Dual-channel configuration for simultaneous signal isolation
- High insulation voltage capability for safety-critical circuits
- NPN phototransistor output for standard logic interfacing
Applications
- Industrial control systems requiring precise isolation
- AC input circuit monitoring and interface
- High-voltage signal transmission in noisy environments
Procurement Notes
Verify the specific suffix E3-A against the manufacturer's latest documentation to confirm lead-free compliance and packaging format. Confirm availability status as distribution channels may vary by region. Ensure the selected variant matches the required surface-mount package dimensions and pinout configuration for the target PCB design.
Selection Notes
Select this component when dual-channel isolation is required within a compact surface-mount footprint. The NPN output type suits applications needing standard transistor switching characteristics. Verify that the 5000 Vrms isolation rating meets the safety standards of the end application. Consider the operating temperature range if the environment exceeds standard commercial limits.
Part Context
This part belongs to the PS2505 series of transistor output optocouplers from CEL. The series includes variants with different channel counts and package types. The PS2505L-2-E3-A specifically denotes the dual-channel version with lead-free construction and tape-and-reel packaging. It is distinct from single-channel or DIP-package versions within the same family.
Replacement Considerations
Direct substitutes must match the 2-channel configuration, 5000 Vrms isolation, and NPN output type. Verify pin compatibility and thermal characteristics before substitution. Cross-reference with other manufacturers' dual-channel SMD optocouplers offering similar CTR and voltage ratings.
