STW6NA90 - High Voltage Power MOSFET by STMicroelectronics

The STW6NA90 is a robust and high-performing N-channel Power MOSFET designed and manufactured by STMicroelectronics. This power transistor is engineered to handle high voltage applications, with a remarkable drain-source voltage (V<sub>DS) of 900V. It is a part of the STPOWER product line, which is known for its efficiency and reliability in power management and conversion applications.

With a continuous drain current (I<sub>D) of 5.8A, the STW6NA90 is capable of driving significant loads while maintaining a low on-resistance (R<sub>DS(on)) of 1.9Ω. This characteristic ensures minimal power loss and heat generation, contributing to the overall efficiency of the system in which it is used.

The device is housed in a TO-247 package, a widely used and sturdy package that offers excellent thermal performance and is suitable for high-power circuits. The TO-247 package also allows for easy mounting on a heatsink, which is critical for maintaining thermal stability during operation at high currents or in high temperature environments.

One of the key features of the STW6NA90 is its avalanche ruggedness, which makes it capable of withstanding harsh operating conditions and enhances its reliability. Additionally, the MOSFET is equipped with a fast-switching capability, which is essential for reducing switching losses in applications such as switch-mode power supplies, lighting, and motor control.

STMicroelectronics has also integrated a Zener-protected gate to safeguard the MOSFET against electrostatic discharge (ESD) events, thereby improving the longevity of the product. The STW6NA90 is designed to meet the stringent requirements of industrial applications and is particularly suited for high-efficiency converters and power management tasks where high voltage and robustness are critical.

In summary, the STW6NA90 from STMicroelectronics is a high-voltage, high-performance Power MOSFET that offers a compelling combination of power handling, efficiency, and reliability for a wide range of industrial and power applications.
