FST8320M Application Field and Working Principle

The FST8320M is a voltage-reduced MOSFET suitable for both synchronous and asynchronous rectification applications. It is a part of the high performance and economical FST8300 series von Funke-Tech rectifiers and arrays family which is designed for low voltage applications. This device is provided in an industry standard SOIC-8 or DIP-8 package with thermally enhanced construction.

The FST8320M is primarily used for the synchronous rectification of AC current in power supplies, LED drivers and other power systems. It is also used for the power regulation and dissipation in other applications like electric motors, power grids, frequency converters, and solar inverters. The current drain resistivity of the power device is typically given in the datasheets and can be used to estimate the power dissipation levels.

The working principle of the FST8320M is based on the principle of voltage-divided MOSFET. This device has two half cells which are connected together in parallel, forming a single cell. The two cells are connected in such a way that the voltages of the two cells are reduced. This means that the drain- source voltage across the MOSFET is different from the source voltage, resulting in a reduced voltage drop and improved efficiency. When considering the design of power rectification systems, designers should ensure that the voltage reduction of the FST8320M is taken into account.

The FST8320M rectifier and array can be configured in several ways to provide full wave rectification, synchronous rectification and dynamic rectification. The full wave rectification and synchronous rectification can be used for smoothing the current of AC input, increasing the efficiency and power pricing. In the dynamic rectification, the device switches quickly between on and off operations, providing high efficiency and power rating. The FST8320M has steady state, forward drop and reverse leakage diode characteristics that make it suitable for dynamic rectification.

Despite its cost-effectiveness, the FST8320M rectifier and array provides a high performance and reliable operation. It has low forward voltage drop which helps to reduce the total power loss and increase the efficiency of the system. The device also has a high power and temperature ratings enabling it to be used in high power applications. In addition, it boasts the high surge current and short circuit protection that are available in much more expensive products.

The FST8320M is an excellent choice for power supply applications which require efficient operation, high power savings and reliability. In addition, its small package size, low cost and high performance make it an excellent option for developers, who are looking to upgrade their existing power supplies without having to sacrifice either quality or performance.
