PS2502-4XG

Overview

The PS2502-4XG is a high-density, four-channel optically coupled isolator manufactured by Isocom Components. It integrates a GaAs infrared emitting diode with an NPN silicon Darlington phototransistor array within a 16-pin Dual In-line Package (DIP). The device provides electrical isolation between input and output circuits, featuring a rated isolation voltage of 5000Vrms. Key electrical parameters include a typical current transfer ratio of 2000% and switching times of 100µs for both rise and fall durations. It operates across a temperature range of -55°C to +100°C and supports a maximum forward current of 80mA per channel.

Feature Summary

Integrates four independent channels of optical isolation within a single compact package
Utilizes NPN silicon Darlington phototransistors for high current gain capability
Provides robust electrical insulation via a 5000Vrms isolation barrier
Designed for surface or through-hole mounting in standard DIP configurations

Applications

Programmable logic controller (PLC) I/O modules
Power supply unit feedback and control circuits
Industrial automation and factory automation equipment
Telecommunications interface isolation

Procurement Notes

Verify the specific suffix 'XG' against official Isocom documentation to confirm exact pinout, lead form, and compliance status. Ensure the selected variant matches the required isolation voltage and current transfer ratio specifications for the target application circuit design.

Selection Notes

Select this component when multi-channel isolation is required in a space-constrained environment. The Darlington output structure offers higher sensitivity compared to single transistor variants, making it suitable for driving loads with lower input currents. Confirm that the 16-pin DIP footprint aligns with the PCB layout requirements.

Part Context

This part belongs to the PS2502 series of high-density photodarlington optocouplers. The series includes single, dual, and quad channel variants in both DIP and surface-mount packages. It serves as a replacement for legacy multi-channel isolators in industrial and communication systems requiring reliable galvanic separation.
