PS2502L-1-F3-K-A

Overview

The CEL PS2502L-1-F3-K-A is a single-channel Darlington output optocoupler featuring a GaAs infrared LED and an NPN silicon phototransistor array. It provides high isolation voltage of 5000 Vrms and a typical current transfer ratio of 2000%. The device supports a maximum forward current of 80 mA and a collector-emitter breakdown voltage of 40 V. Operating temperature ranges from -55 °C to 100 °C, with rise and fall times typically at 100 µs.

Feature Summary

High isolation voltage capability for safe signal transmission across potential differences
Darlington transistor output configuration enables high current gain and sensitivity
Surface mount Gull-wing package design facilitates automated PCB assembly

Applications

Power supply circuits requiring galvanic isolation
Telephone and fax machine interface modules
Industrial automation control systems

Procurement Notes

Verify the specific suffix K-A against manufacturer documentation to confirm tape-and-reel packaging specifications and terminal finish details. Ensure compatibility with surface mount reflow soldering profiles. Cross-reference UL recognition number E72422 for safety compliance requirements in end-use equipment certification processes.

Selection Notes

Select this component when high current transfer ratio is required for driving loads directly without additional amplification. The Darlington output structure suits applications needing significant gain from low input currents. Verify that the 40 V collector-emitter voltage rating meets the load requirements of the isolated circuit side.

Part Context

This part belongs to the PS2502L series of high-isolation voltage Darlington type photocouplers manufactured by CEL (California Eastern Laboratories). The series includes DIP and surface mount variants designed for robust electrical isolation in noisy environments. The L-series designation indicates lead bending type packages suitable for surface mounting technologies.
