STP38N65M5 - N-channel 650 V, 0.033 Ω typ., 34 A MDmesh™ M5 Power MOSFET in a TO-220 package

The STP38N65M5 is a high-performance N-channel Power MOSFET from STMicroelectronics, designed using the innovative MDmesh™ M5 technology. This device is tailored for applications requiring high efficiency and power density. It is housed in a robust TO-220 package, which is well-suited for through-hole mounting, making it a versatile choice for various power supply and switching applications.

With a drain-source voltage (V<sub>DS) of 650 V, the STP38N65M5 is capable of handling high voltage applications while providing a low on-resistance (R<sub>DS(on)) of just 0.033 Ω (typical). This low on-resistance minimizes conduction losses, making the MOSFET an excellent choice for improving energy efficiency in electronic circuits.

The device boasts a continuous drain current (I<sub>D) of 34 A at 25°C, which allows it to drive significant loads. This high current capability, combined with the fast-switching performance, makes the STP38N65M5 suitable for a wide range of applications, including switch-mode power supplies (SMPS), LED lighting, high-efficiency converters, and motor control systems.

The MDmesh™ M5 technology integrates a vertical structure, which optimizes the R<sub>DS(on) versus the drain current capability, providing an excellent figure of merit for high-efficiency power conversion. Additionally, the MOSFET features Zener-protected gate, which helps to enhance reliability and protect against overvoltage transients.

Moreover, the STP38N65M5 is characterized by a low gate charge (Q<sub>g), which reduces switching losses and enables faster switching frequencies. This characteristic, along with the device's low intrinsic capacitances, ensures reduced switching times and enhanced overall performance.

STMicroelectronics is committed to environmental sustainability, and the STP38N65M5 is designed in accordance with the company's focus on creating energy-saving products. It complies with the stringent European RoHS directive, which restricts the use of hazardous substances in electrical and electronic equipment.

In summary, the STP38N65M5 Power MOSFET from STMicroelectronics is a robust and efficient solution for designers looking to optimize their power management systems with a reliable and high-performing component.
