STMicroelectronics STD40N2LH5 Power MOSFET

The STMicroelectronics STD40N2LH5 is a high-performance N-channel Power MOSFET designed to deliver efficiency and reliability for a wide range of applications. This device is part of STMicroelectronics' STripFET H5 series, which is known for its low on-state resistance and low gate charge, making it an excellent choice for power management tasks.

With a 40V drain-source breakdown voltage (V<sub>DS), the STD40N2LH5 is suitable for applications that require a moderate voltage range. It can handle continuous drain currents (I<sub>D) up to 80A, making it capable of supporting high current loads. The low threshold voltage ensures that the MOSFET can be driven at lower gate voltages, enhancing its compatibility with a broader range of drive circuits and controllers.

The STD40N2LH5 features an ultra-low on-state resistance (R<sub>DS(on)) of just 2.5 mΩ at a gate voltage of 10V. This characteristic minimizes conduction losses and helps improve the overall efficiency of the device in applications such as DC/DC converters, motor control circuits, and power management systems.

STMicroelectronics has packaged the STD40N2LH5 in a surface-mount DPAK (TO-252), which is widely used in the industry and allows for efficient thermal dissipation and space-saving on printed circuit boards. The device is also 100% avalanche tested, ensuring robustness and reliability under harsh operating conditions.

The STD40N2LH5 is designed with the environment in mind, as it is compliant with RoHS and Halogen-free requirements, making it a suitable choice for eco-friendly and energy-efficient designs. Its fast switching speed and low gate charge are beneficial for high-frequency circuits, reducing switching losses and improving performance.

In summary, the STD40N2LH5 from STMicroelectronics is a high-quality Power MOSFET that offers a balanced combination of low on-resistance, high current capability, and energy efficiency. It is an ideal component for designers looking to optimize their power management solutions in a variety of industrial, automotive, and consumer applications.
