The STL3N80K5 is a N-Channel Enhancement Mode MOSFET featuring STMicroelectronics’ Green【TM】technology. It is able to reduce power consumption significantly compared to the normal current level. This MOSFET is specially designed to reduce the RDS(on), the sourse-drain voltage and the switching losses in order to improve efficiency. This device is also designed to minimize the impact of the conditions typically associated with heavy and long operating conditions.

STL3N80K5 is well suited for Low-Frequency Switching and high-speed Power Switching applications. It is designed for high-efficiency power conversion circuit, mainly applied to Buck,Boost,Inverting and Buck-Boost converters. It is usually used in the DC-DC converter to step-down the output voltage and enhance the system efficiency. In addition, it can be used in the input stage of the pre-drive circuit, allowing low turn off losses.

Working Principle of STL3N80K5

The STL3N80K5 has an N-channel enhancement mode MOSFET structure and is mainly composed of three components: the source, the gate and the drain. When a small amount of voltage is applied to the gate, the STL3N80K5 works as a closed switch, allowing a large amount of current to flow from the source to the drain. If the gate is not supplied with any voltage, no current flows from the source to the drain, acting as an open switch.

Furthermore, the device has thermal stability and temperature compensation, which reduces the risk of thermal runaways. The device is also designed with an extended SOA (Safe Operating Area). This allows the device to be driven safely at higher voltages, currents and speeds without compromising the quality and reliability of the device.

The device also has two main characteristics: the current level and the voltage drop. The maximum current that the device can support is whether AC or DC, it is determined by the maximum temperature that the device can safely withstand. The voltage drop is proportional to the resistance of the load, as well as the applicable current and the temperature levels.

Conclusion

The STL3N80K5 is one of the most popular N-channel enhancement mode MOSFETs in the market today. This device has a wide range of applications and is especially useful in high-efficiency power conversion circuits. It is able to reduce power consumption significantly compared to conventional current levels and is designed to provide improved performance and increased safety features.
