PS2505-4XSM

Overview

The PS2505-4XSM is a surface-mount optically coupled isolator manufactured by Isocom Components. It features four channels of NPN silicon phototransistor outputs driven by infrared LEDs connected in inverse parallel for AC input compatibility. The device provides high isolation voltage and operates within a temperature range of -30°C to +100°C.

Feature Summary

• AC input response capability via inverse parallel LED configuration
• High isolation voltage rating for signal transmission between systems of different potentials
• Surface mount packaging designed for high density mounting applications

Applications

• Computer terminals
• Industrial system controllers
• Signal transmission between systems of different potentials and impedances

Procurement Notes

Verify the specific suffix 'XSM' against official manufacturer documentation to confirm exact pinout, lead spread, and tape-and-reel specifications. Ensure the component matches the required surface mount package dimensions and electrical parameters before integration into designs.

Selection Notes

Select this component when AC input detection or polarity-insensitive operation is required for multi-channel isolation. Consider the surface mount form factor for automated assembly processes and high-density PCB layouts requiring compact footprint solutions.

Part Context

This part belongs to the PS2505 series of high-density AC input phototransistor optocouplers. The series is characterized by its ability to handle AC signals directly without external rectification, offering a robust solution for digital isolation in space-constrained electronic assemblies.
