PS2561L2-1

Overview

The CEL PS2561L2-1 is a single-channel transistor output optocoupler featuring an NPN silicon phototransistor and a GaAs infrared LED. It provides high isolation voltage of 5000 Vrms with a typical current transfer ratio of 2000%. The device supports a maximum collector-emitter voltage of 40 V, forward current of 80 mA, and operates within a temperature range of -55°C to +100°C.

Feature Summary

High isolation voltage capability for safe signal transmission
Photodarlington output structure for high gain
Lead bending design for extended creepage distance

Applications

AC input detection circuits
Industrial control systems
Power supply feedback loops

Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm RoHS compliance details via official datasheets. Check regional availability restrictions as distribution may be limited. Validate package specifications against PCB footprint requirements before integration.

Selection Notes

Select this component for applications requiring high isolation and Darlington output gain. Ensure circuit design accommodates the specified saturation voltage and power dissipation limits. Verify thermal management capabilities for operation near maximum temperature ratings.

Part Context

This part belongs to the PS2561 series of single-channel optocouplers. It utilizes a lead-bending Gull-wing surface mount package designed for long creepage distances. The series is manufactured by CEL under the Renesas Electronics portfolio.
