Single FETs, MOSFETs Procurement Notes

Verify the complete part number including suffixes such as -E1-AY against official NEC/Renesas documentation to ensure correct packaging and compliance status. Confirm RoHS3 and MSL classifications match project requirements. Cross-reference datasheet revisions to validate electrical parameters before integration into final designs.

Single FETs, MOSFETs Selection Notes

Select this component when a 40V N-channel MOSFET with high current handling is required in a compact surface-mount form factor. Evaluate thermal resistance characteristics relative to the PCB layout and heat sinking strategy. Ensure gate drive voltage compatibility with the specified 4.5V or 10V thresholds for optimal Rds(on) performance.

Single FETs, MOSFETs Part Context

This device belongs to the NEC Corporation (now Renesas Electronics) discrete power transistor portfolio. It is designed for general-purpose power switching where moderate voltage blocking and high current capacity are necessary. The TO-252 package provides a balance between thermal performance and board space efficiency compared to through-hole alternatives.

Single FETs, MOSFETs Replacement Considerations

Consult official substitution guides for equivalent N-channel MOSFETs with matching 40V Vdss and similar Id ratings. Verify pinout compatibility and package dimensions before replacing. Do not assume functional interchangeability without validating thermal and electrical specifications against the original datasheet.
