PS2506L-1-E3-A

Overview

The CEL PS2506L-1-E3-A is a single-channel transistor output optocoupler featuring a GaAs infrared LED and an NPN silicon Darlington phototransistor. It provides high isolation voltage of 5000 Vrms, suitable for AC input applications. The device supports a maximum forward current of 80 mA with a typical current transfer ratio of 2000%. It operates within a temperature range of -55°C to +100°C and is housed in a surface-mount Gull-wing package.

Feature Summary

High isolation voltage capability for safe signal transmission across potential barriers
AC input compatibility utilizing a Darlington output configuration for high gain
Surface-mount Gull-wing package design for automated assembly integration

Applications

Industrial control systems requiring galvanic isolation
AC-powered equipment interface circuits
Signal transmission between isolated logic levels

Procurement Notes

Verify the specific suffix E3 against official datasheets to confirm lead-free compliance status. Confirm package type matches the Gull-wing surface mount variant rather than through-hole DIP. Check manufacturer lifecycle status as discontinuation may affect long-term availability. Ensure supplier documentation aligns with the exact part number designation.

Selection Notes

Select this component when high isolation voltage and AC input compatibility are required. The Darlington output offers higher current transfer ratio compared to standard phototransistors. Verify that the surface-mount form factor fits the PCB layout constraints. Consider thermal dissipation limits within the specified operating temperature range during circuit design.

Part Context

This part belongs to the NEPOC series of optically coupled isolators manufactured by CEL. It shares architectural similarities with other PS2506 variants but differs in packaging and termination style. The series is designed for general-purpose isolation tasks where robust electrical separation is critical.
