Procurement Notes

Verify the specific manufacturer designation, as sources indicate both Infineon Technologies and International Rectifier branding for this part number. Confirm the RoHS compliance status, as conflicting data exists regarding lead content. Check the current product lifecycle status, as some records classify the item as obsolete. Ensure the datasheet matches the required 1.4A or 5A specification variant before procurement to avoid functional mismatches.

Selection Notes

Select this component when a compact N-channel high-side switch is required for low-current applications up to 1.4A. Consider the 8-SOIC package constraints for PCB layout and thermal dissipation. Evaluate the availability of official documentation from Infineon or its predecessor entities to ensure accurate pinout and electrical characteristic verification during the design phase.

Part Context

This part belongs to the Power Distribution Switches and Load Drivers category, specifically focusing on integrated MOSFET solutions. It represents a legacy product line often associated with International Rectifier, now under Infineon Technologies. The component serves as a fundamental building block for simple load control tasks where discrete MOSFETs would consume excessive board space.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify cross-references through official Infineon databases or authorized distributors to identify compatible modern equivalents that meet the same 8-SOIC footprint and N-channel switching requirements.
