PS2502-2-A

Overview

The PS2502-2-A is a Darlington output optocoupler manufactured by CEL, featuring two independent channels within an 8-DIP package. It provides high isolation voltage of 5000 Vrms between input and output circuits. The device utilizes an NPN photodarlington output configuration, supporting a maximum collector current of 200 mA per channel. Key electrical parameters include a typical current transfer ratio of 2000% at a forward current of 5 mA, with a maximum DC forward current rating of 80 mA. The unit operates within a temperature range of -55°C to +100°C.

Feature Summary

High isolation voltage capability for safe signal transmission across potential barriers
Darlington output structure enables high current gain and sensitivity
Dual-channel configuration allows simultaneous isolation of two signals in a single package

Applications

AC mains detection circuits requiring galvanic isolation
Solid-state relay driver interfaces
Microcontroller I/O isolation for industrial control systems

Procurement Notes

Verify the specific suffix '-A' against the manufacturer's latest datasheet to confirm compliance status and pinout compatibility. Ensure the source document explicitly lists this part number variant, as generic listings may refer to similar models without the exact electrical tolerances or packaging specifications associated with the '-A' designation.

Selection Notes

Select this component when high current drive capability is required from a low-power LED input. The Darlington output architecture offers superior current transfer efficiency compared to standard phototransistor outputs. Consider the thermal dissipation limits of the DIP-8 package if operating near maximum current ratings.

Part Context

This component belongs to the PS2502 series of optocouplers, which are designed for general-purpose isolation applications. The series typically includes variants with different channel counts and output types. The PS2502-2-A specifically denotes the dual-channel version with Darlington outputs, distinguishing it from single-channel or transistor-output alternatives in the same family.
