Overview
The CEL PS2565L-2 is a dual-channel transistor output optocoupler featuring an NPN silicon phototransistor and a GaAs infrared LED. It provides 5000 Vrms isolation voltage for robust signal transmission across isolated circuits. The device supports a maximum collector-emitter voltage of 80V and a continuous collector current of 50mA per channel. With a typical current transfer ratio of 100% at 5mA forward current, it ensures reliable switching performance. Operating temperatures range from -55°C to +100°C, suitable for industrial environments.
Feature Summary
- Dual-channel configuration with independent AC/DC input compatibility
- High isolation voltage rating for safe circuit separation
- Phototransistor output designed for high-speed switching applications
Applications
- Industrial automation control systems
- Power supply feedback loops
- Microcontroller interface isolation
Procurement Notes
Verify component authenticity through authorized distributors due to discontinued status. Check datasheet revisions for pinout consistency. Confirm RoHS compliance documentation matches specific manufacturing lot requirements. Ensure storage conditions adhere to moisture sensitivity levels specified in the package information to prevent degradation before assembly.
Selection Notes
Select this model when dual-channel isolation is required within a single package footprint. Compare current transfer ratio specifications against load requirements to ensure adequate drive capability. Verify package dimensions match PCB layout constraints. Consider thermal dissipation limits if operating near maximum temperature ratings or high duty cycles.
Part Context
Part of the PS2565 series, which includes single-channel variants like PS2565-1 and surface-mount versions like PS2565L-1. This family emphasizes cost-effective isolation solutions using standard DIP packaging. The L-series typically denotes lead-free or specific material composition variations compared to older generations.
Replacement Considerations
Official substitutes include PS2565-2-V for equivalent performance in 8-DIP packages. Cross-reference pinouts carefully when replacing with generic equivalents. Verify that alternative components meet the same 5000 Vrms isolation and 80V collector voltage ratings.
