IS452

Overview

The IS452 is a single-channel optocoupler manufactured by Isocom Components 2004 LTD. It features a DC input and a high-voltage Darlington transistor output, housed in a 4-pin PDIP package. Key electrical specifications include a maximum forward voltage of 1.4V for the input side and an isolation voltage rating of 3750 Vrms. The device supports a collector current of 50 mA and offers a current transfer ratio of 1000%. This component is designed for surface mount applications requiring reliable electrical isolation between circuits.

Feature Summary

High-voltage Darlington output configuration for robust signal transmission
Single-channel design providing efficient circuit isolation
Surface-mount packaging suitable for automated assembly processes

Applications

Industrial control systems requiring galvanic isolation
Power supply feedback loops
Signal interfacing between low-voltage logic and high-voltage loads

Procurement Notes

Verify the specific package variant (PDIP vs SMD) as sources indicate conflicting mounting types. Confirm datasheet revisions to ensure compatibility with current design requirements. Check distributor availability for bulk or cut-tape options if needed. Ensure the supplier is authorized to guarantee component authenticity and traceability.

Selection Notes

Select this component when a high-current transfer ratio is required for driving loads directly from the output stage. The Darlington configuration allows for higher gain compared to standard phototransistor outputs. Consider the 3750 Vrms isolation rating for safety-critical applications. Verify thermal management needs based on the 50 mA collector current specification.
