Procurement Notes

Verify the specific suffix USA1 against the official Infineon datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with system voltage requirements and thermal management needs. Cross-reference the ordering number with the manufacturer's current product status to confirm availability and lead time constraints before finalizing procurement plans.

Selection Notes

Select this component for applications requiring high-speed switching with moderate drive current in a compact surface-mount footprint. The low-side topology suits half-bridge or single-switch configurations where the load connects to the positive rail. Consider the 20 V maximum supply limit when designing bootstrap or isolated power stages for high-voltage primary sides.
