Procurement Notes
Verify the complete part number including the suffix to ensure correct packaging and tape-and-reel specifications. Confirm that the TO-220AB package dimensions match your PCB footprint requirements. Check datasheet revisions for any updates to thermal characteristics or maximum ratings before finalizing design specifications.
Selection Notes
Select this component when a 100 V rating and 39 A continuous current capacity are required in a through-hole package. Ensure adequate heatsinking is provided to maintain junction temperatures within limits during operation. Compare Rds(on) values against alternative packages if space constraints allow for surface-mount solutions.
Part Context
This device belongs to Nexperia's BUK95 series of power MOSFETs, which are engineered for general-purpose power switching applications. The series offers a balance of voltage rating, current handling, and thermal performance, making it suitable for various industrial and consumer electronics designs requiring reliable N-channel switching.
Replacement Considerations
Consult official Nexperia substitution guides for compatible alternatives. Verify pinout compatibility and electrical parameters such as Vgs(th) and Rds(on) when considering cross-brand replacements to ensure circuit functionality remains unaffected.
