NXP BUK768R1-40E: A High-Performance 40V Automotive TrenchMOS Power MOSFET

The demand for robust and efficient power management solutions continues to grow in the automotive sector, driven by the increasing electrification of vehicles and advanced driver-assistance systems (ADAS). At the heart of many of these applications lies the power MOSFET, a critical component for switching and controlling electrical power. The NXP BUK768R1-40E stands out as a premier solution, engineered to meet the stringent requirements of modern automotive electronics.

This device is a 40V, single N-channel TrenchMOS transistor optimized for high-performance switching applications. It is specifically designed for use in automotive environments, where reliability under harsh conditions is non-negotiable. The transistor boasts an extremely low typical on-resistance (RDS(on)) of just 0.8 mΩ, a feature that directly translates into superior efficiency. This low resistance minimizes conduction losses, leading to less heat generation and higher overall system efficiency, which is crucial for improving fuel economy and battery life in electric and hybrid vehicles.

Built using NXP's advanced TrenchMOS technology, the BUK768R1-40E offers excellent switching performance and high robustness. Its AEC-Q101 qualification ensures it meets the rigorous quality and reliability standards demanded by the automotive industry. The device is highly suitable for a wide range of applications, including:

DC-DC converters in infotainment and powertrain systems.

Motor control modules for electric power steering (EPS), pumps, and fans.

Load switches and solid-state relays in body control modules.

Battery management systems (BMS).

The package is also designed for optimal thermal performance, ensuring effective heat dissipation even under high-load conditions. Furthermore, its lead-free and halogen-free design aligns with global environmental regulations.

ICGOOFind: The NXP BUK768R1-40E is a top-tier automotive-grade Power MOSFET that sets a high benchmark for performance and reliability. Its exceptional combination of ultra-low RDS(on), high power density, and automotive qualification makes it an ideal and future-proof choice for designers tackling the power challenges in next-generation vehicles.
