PS2566L-2

Overview

The PS2566L-2 is a two-channel optically coupled isolator from the NEPOC series, manufactured by CEL. It integrates GaAs light-emitting diodes with NPN silicon Darlington-connected phototransistors in an 8-SMD surface-mount package. The device features high isolation voltage of 5000 Vrms and AC input response capability. Key electrical parameters include a minimum current transfer ratio of 2000%, maximum forward current of 80 mA, collector-emitter breakdown voltage of 40 V, and maximum dark power of 400 nA. Operating temperature range spans from -55 °C to 100 °C.

Feature Summary

AC input response capability for direct AC signal coupling
High isolation voltage rating of 5000 Vrms
Surface mount Gull-wing lead bending type for long creepage distance
Dual channel configuration with Darlington output structure

Applications

Signal processing in isolated circuits
AC input detection systems
Industrial control interface isolation

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm RoHS compliance status as datasheets indicate potential non-compliance depending on specific suffix variants. Check packaging quantity and lead finish specifications (Tin/Lead) against project requirements. Ensure ordering part number matches exact pin configuration and insulation class needs.

Selection Notes

Select this component when dual-channel isolation with high current transfer ratio is required. Suitable for applications needing AC input compatibility without additional rectification circuitry. Consider thermal management within specified operating temperature range. Verify creepage distance requirements match the Gull-wing package design for safety standards compliance.

Part Context
