Single FETs, MOSFETs Procurement Notes

Verify the manufacturer designation carefully, as International Rectifier technology is now integrated into Infineon Technologies' portfolio. Confirm the specific suffix 'TR' indicates tape-and-reel packaging if required for automated assembly. Ensure the component meets the necessary automotive qualification standards relevant to your specific application environment before finalizing procurement.

Single FETs, MOSFETs Selection Notes

Select this component when a 55 V N-channel MOSFET with low Rds(on) is required for automotive or industrial applications. The SOT-223 package suits space-constrained designs needing surface-mount capabilities. Consider the 1.9 A current rating against your peak load requirements to ensure adequate thermal headroom without excessive heatsinking.

Single FETs, MOSFETs Part Context

This discrete semiconductor belongs to the Single FETs family within the broader MOSFET category. As part of Infineon's legacy IR product line, it represents a standard solution for small-signal power switching. The component is distinct from high-power modules, focusing instead on individual transistor performance for precise circuit control.

Single FETs, MOSFETs Replacement Considerations

Direct substitutes include other 55 V N-channel MOSFETs in SOT-223 packages with comparable Rds(on) and Id ratings. Verify pinout compatibility and thermal characteristics before swapping. Cross-reference with Infineon's current portfolio for updated equivalents.
