This advanced component combines cutting-edge technology with exceptional performance metrics, making it an indispensable solution for modern power management systems. Designed for engineers seeking reliability and efficiency in compact electronic designs, this 60V 42A MOSFET represents the sixth generation of ST's PowerFlat™ technology.

Technical Excellence in Compact Packaging

Housed in an 8-PowerVDFN package measuring just 5x6mm, the STL42P6LLF6 achieves remarkable power density while maintaining exceptional thermal performance. Its PowerFlat™ packaging technology eliminates the traditional bond wires, reducing parasitic inductance and improving current handling capabilities. This surface-mount device (SMD) is specifically engineered for high-efficiency switching applications where space constraints demand miniaturization without compromising performance.

The device's core specifications demonstrate its engineering prowess: With a maximum drain-source voltage (Vdss) of 60V and a continuous drain current of 42A at 25°C, it maintains a remarkably low Rds(on) of just 26mΩ at 4.5V Vgs. This exceptional conductivity translates to significant power savings and reduced heat generation in critical applications. The advanced trench gate technology enables fast switching characteristics, with a gate charge (Qg) of 30nC at 4.5V, making it ideal for high-frequency operations.

Thermal Mastery and Reliability

Engineered for demanding environments, the STL42P6LLF6 demonstrates exceptional thermal stability with a maximum operating temperature of 175°C. Its ±20V gate voltage tolerance provides robustness against voltage spikes, while the 3780pF input capacitance at 25V ensures stable operation in high-speed switching circuits. The device's 100W power dissipation rating (at case temperature) enables reliable performance in power-hungry applications without requiring excessive heatsinking.

This MOSFET's versatility shines in automotive electronics, industrial power supplies, and battery management systems. Its combination of high current capability, low on-resistance, and compact footprint makes it particularly well-suited for DC-DC converters, motor controllers, and load switching applications where efficiency and space optimization are critical.

Applications and Design Advantages

In automotive contexts, the STL42P6LLF6 excels in body control modules, powertrain systems, and onboard charging circuits. Its AEC-Q101 qualification ensures reliability in vehicle environments with wide temperature variations. For industrial applications, its robust design enables efficient power distribution in programmable logic controllers (PLCs) and factory automation equipment.

Design engineers benefit from the device's compatibility with standard 4.5V-10V gate drive circuits, simplifying integration with existing controller ICs. The low gate charge reduces driver power requirements, while the fast switching characteristics minimize switching losses. When compared to competing solutions, the STL42P6LLF6 demonstrates superior performance density - delivering 42A capability in a 5x6mm package with industry-leading thermal management.
