STH16NA40FI - N-Channel 400V - 0.16 Ohm - 16A - TO-220/FP/D2PAK/I2PAK - Fully Avalanche Rated - SuperMESH™ Power MOSFET

The STH16NA40FI is a state-of-the-art N-Channel Power MOSFET presented by STMicroelectronics, part of their renowned SuperMESH™ family. This high-performance MOSFET is designed to meet the requirements of a wide range of electronic applications, particularly in the power supply, lighting, motor control, and industrial sectors. It is housed in a variety of packages including TO-220, TO-220FP, D2PAK, and I2PAK, providing flexibility for different assembly techniques and thermal requirements.

With a drain-source voltage (V_DS) of 400V and a low on-resistance (R_DS(on)) of just 0.16 Ohm, the STH16NA40FI is optimized for high efficiency and power density. The device can handle continuous drain currents (I_D) up to 16A, making it suitable for high-power applications. Its fully avalanche rated design ensures robustness and reliability under harsh operating conditions, including those where the MOSFET may be subjected to high energy pulses.

The SuperMESH™ technology combines a vertical structure with a patented strip layout, yielding one of the best-in-class on-resistance versus gate charge trade-offs, which is critical for high-efficiency power conversion. This technology also provides a significant reduction in total gate charge (Q_g) and improved diode recovery characteristics, which are essential features for improving the performance of resonant and soft-switching topologies.

Furthermore, the STH16NA40FI features a fast switching speed and a low gate charge, which reduces the switching losses and thus improves the overall efficiency of the power conversion system. The device is also characterized by its low threshold voltage (V_th), which enhances its threshold stability and endurance to the temperature variations, ensuring a consistent performance across a wide range of operating conditions.

For safety and protection, the STH16NA40FI is equipped with an intrinsic fast-recovery body diode, which provides a safeguard against reverse current conditions. This makes it an excellent choice for applications that require a high level of reliability and operational safety.

In conclusion, the STH16NA40FI from STMicroelectronics is an advanced power MOSFET that combines high voltage capability, low on-resistance, high current handling, and robustness, making it an ideal choice for designers seeking to improve the efficiency and reliability of their power management systems.
