IS2801-4

Overview

The IS2801-4 is a four-channel surface-mount optocoupler from Isocom Components, housed in a 16-pin SOP package. Each channel integrates an infrared LED with an NPN silicon phototransistor output. The device provides 2500V isolation and features a typical response time of 2μs. Designed for high-density mounting on hybrid substrates, it supports DC input applications.

Feature Summary

• Four independent channels within a single compact surface-mount package
• Optical coupling between infrared LED input and NPN phototransistor output
• High electrical isolation capability for signal integrity

Applications

• Hybrid substrate systems requiring high-density mounting
• Programmable logic controllers (PLCs)
• AC/DC input modules for industrial automation

Procurement Notes

Verify the specific ordering suffix against the official datasheet to confirm pinout compatibility and packaging type. Ensure the component meets the required isolation voltage ratings for the target circuit. Cross-reference the manufacturer part number with authorized distributors to confirm current availability and authenticity before procurement.

Selection Notes

Select this component when a multi-channel isolation solution is required in a small footprint. It serves as a direct replacement for similar quad-channel optocouplers from other manufacturers. Consider the SOP-16 package constraints and ensure the PCB layout accommodates the specific lead pitch and thermal requirements.

Part Context

This part belongs to Isocom's compact range of optocouplers, designed to replace discontinued or hard-to-find components from major brands like Toshiba and Avago. It fits into the broader category of digital isolators used in control systems where space efficiency and reliable signal transmission are critical.
