Overview
The PS2505L-1-E3-A is a single-channel transistor output optocoupler manufactured by CEL. It integrates an AlGaAs light-emitting diode with an NPN silicon phototransistor for signal isolation. Key electrical parameters include a maximum collector-emitter voltage of 80 V, a maximum collector current of 50 mA, and a forward voltage of 1.4 V at 80 mA input current. The device offers a high isolation voltage of 5000 Vrms and operates within a temperature range of -55°C to +100°C. Power dissipation is rated at 150 mW.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits using optical coupling technology.
- Features AC input response capability suitable for direct connection to AC power lines without additional rectification.
- Utilizes an NPN phototransistor output stage for reliable digital signal transmission across the isolation barrier.
Applications
- Solid-state relays requiring galvanic isolation
- Microcontroller interface circuits for noise immunity
- Power supply feedback loops
Procurement Notes
Verify the specific suffix E3-A against the manufacturer's latest documentation to confirm RoHS compliance status and pinout configuration. Ensure the ordering part number matches the required package type and channel count. Cross-reference with official distributor catalogs to confirm current availability and lifecycle status before finalizing procurement plans.
Selection Notes
Select this component when a single-channel isolation solution with AC input compatibility is required. Consider the 5000 Vrms isolation rating for safety-critical applications. Evaluate the 80 V collector-emitter voltage limit to ensure it meets the load requirements. Compare propagation delays if high-speed switching is necessary for the target application design.
Part Context
This component belongs to the PS2505L series of optocouplers designed for general-purpose isolation. The series typically includes variants with different channel counts and packaging options. The E3-A suffix generally indicates environmental compliance and specific tape-and-reel packaging for surface-mount assembly processes.
Replacement Considerations
Direct replacements may include the PS2505L-1 or PS2505L-1-F3-A from compatible manufacturers. Verify pin compatibility and electrical specifications such as CTR and isolation voltage before substitution. Consult official datasheets for mechanical footprint differences.
