Procurement Notes
Verify the specific ordering suffix
Selection Notes
Select this component for high-current automotive applications requiring robust thermal performance and standard gate drive compatibility. Ensure the design accommodates the 120 A package-limited current and utilizes adequate heatsinking to manage the 293 W power dissipation potential. Verify that the application voltage remains within the 40 V drain-source limit.
Part Context
This part belongs to Nexperia's BUK76 series of N-channel TrenchMOS FETs designed for automotive use. It shares the SOT404 package form factor with other variants in the lineup but is distinguished by its specific 40 V rating and low on-resistance characteristics optimized for 12 V system architectures.
Replacement Considerations
BUK762R0-40E is listed as End of Life. Consider BUK761R7-40E,118 as a potential alternative within the same family, though verification of pinout and electrical parameters against the original design requirements is necessary.
