PS2561L-1

Overview

The CEL PS2561L-1 is a single-channel transistor output optocoupler featuring a GaAs infrared LED and an NPN silicon phototransistor. It provides high isolation voltage of 5000 Vrms. The device utilizes a lead bending type (Gull-wing) package designed for surface mount applications. Key electrical characteristics include a collector-emitter breakdown voltage of 80V, a maximum forward current of 50mA, and a typical rise/fall time of 3µs/5µs. It operates within a temperature range of -55°C to +100°C.

Feature Summary

High isolation voltage capability of 5000 Vrms
Surface mount Gull-wing lead bending package design
Integration of GaAs LED with NPN phototransistor

Applications

Industrial control systems requiring signal isolation
Power supply feedback circuits
Microprocessor input/output interface isolation

Procurement Notes

Verify the specific suffix code against official datasheets to confirm package type and compliance status. Confirm availability as distribution status may vary. Ensure the selected variant matches the required surface mount configuration and insulation voltage ratings for the target application environment.

Selection Notes

Select this component when surface mount assembly is required alongside high isolation voltage needs. Compare CTR ranges and switching speeds against system requirements. Verify thermal management capabilities within the specified operating temperature range. Ensure compatibility with PCB footprint dimensions for the Gull-wing package.

Part Context

This part belongs to the NEPOC series of high isolation voltage single transistor type multi photocouplers. It shares core functional architecture with through-hole DIP variants but differs in package geometry. The series emphasizes cost-performance balance while maintaining robust electrical isolation standards for industrial environments.
