BUK6D30-40EX

Overview

The BUK6D30-40EX is an N-channel enhancement mode Field-Effect Transistor utilizing Trench MOSFET technology. It operates within a 40 V drain-source voltage range and supports up to 18 A continuous drain current at 25 °C solder point temperature. The device features a maximum on-state resistance of 30 mΩ at 25 °C, rising to 57 mΩ at 175 °C. Total power dissipation reaches 19 W under standard thermal conditions. The component is housed in a leadless DFN2020MD-6 (SOT1220) package with side wettable flanks.

Feature Summary

AEC-Q101 qualified for automotive reliability standards
Extended junction temperature rating up to 175 °C
Side wettable flanks enable optical solder joint inspection
ESD protection exceeding 2 kV Human Body Model rating

Applications

Relay driver circuits

Procurement Notes

Verify the specific suffix 'EX' against the official Nexperia ordering information table to confirm packaging details such as reel specifications or tape-and-reel dimensions. Ensure the procurement documentation matches the exact part number variant required for your assembly process. Cross-reference the marking code '6K' to validate physical unit authenticity upon receipt.

Selection Notes

Select this component when designing low-side switches requiring high thermal endurance up to 175 °C. The DFN2020MD-6 package provides a compact footprint suitable for space-constrained PCB layouts. Verify that the gate drive voltage meets the logic level requirements for optimal RDS(on) performance. Consider the transient thermal impedance characteristics for pulsed load applications.
