PS2565L-2-V

Overview

The PS2565L-2-V is a two-channel optically coupled isolator from the NEPOC series, manufactured by CEL. It integrates GaAs light-emitting diodes with NPN silicon phototransistors in an 8-SMD surface-mount package. The device supports AC and DC input signals and provides high isolation voltage of 5000Vrms. Key electrical characteristics include a typical current transfer ratio (CTR) of 200% at 5mA forward current, with a maximum CTR of 400%. The output can handle up to 80V and 50mA per channel. Switching performance features typical rise and fall times of 3µs and 5µs respectively, operating within a temperature range of -55°C to 100°C.

Feature Summary

• Dual-channel configuration for independent signal isolation
• High isolation voltage rating for safety compliance
• Surface-mount Gull-wing lead bending type for PCB integration
• AC input response capability

Applications

• Industrial control systems requiring galvanic isolation
• Power supply feedback loops
• Signal transmission between microcontrollers and high-voltage circuits
• Solid-state relay driver interfaces

Procurement Notes

Verify component authenticity through authorized CEL distributors or certified suppliers. Confirm RoHS compliance status and check for specific ordering suffixes that may indicate tape-and-reel packaging versus tube quantities. Ensure the part number matches the exact pinout and package dimensions required for your design. Review the latest datasheet for any updates on recommended soldering profiles or storage conditions prior to assembly.

Selection Notes

Select this component when dual-channel isolation is required in a compact surface-mount form factor. The 5000Vrms isolation rating suits applications demanding robust safety barriers. Consider the 200% typical CTR for efficient drive requirements. Verify that the 80V output voltage limit meets the load specifications. Ensure the 3µs/5µs switching speeds are sufficient for the target signal frequency. Compare against single-channel alternatives if only one isolated path is needed.

Part Context

This device belongs to the PS2565/PS2566 NEPOC series, which includes variants with Darlington outputs (PS2566) and standard phototransistor outputs (PS2565). The 'L' designation indicates a lead-bending type package suitable for surface mount technology. The '2' denotes a two-channel configuration. Other series members include PS2565-1, PS2565-2, and PS2566L-1, offering different channel counts and output types in DIP or SMD packages.

Replacement Considerations

Direct substitutes include PS2565L-2-E3 or PS2565L-2-F3 from the same manufacturer family, assuming identical pinout and electrical parameters. Cross-brand replacements must match the 5000Vrms isolation, 8-SMD package, and dual-channel transistor output configuration. Verify compatibility with existing PCB footprints and thermal management requirements before substitution.
