The FST31180 is a diode rectifier module array, comprising three phase rectifiers configured to provide an output of up to 800A continuous or 1,000A rated surge current. The rectifiers utilize two independent positive temperature coefficient (PTC) thermistors to protect the module from high inrush current. The FST31180 rectifiers are designed to be integrated into a variety of power systems, including power supplies, motor starters, and converters.

The FST31180 provides a high degree of thermal stability and power dissipation, with a maximum junction temperature of 175°C. Applications for the FST31180 include server, medical, and industrial power supplies, uninterruptible power systems, and power electronics. The rectifiers can also be used for lighting applications and for controlling the flow of electric current in a wide variety of other electronic devices.

The working principle of the FST31180 module is based on a rectifying circuit, which is composed of three diodes. The input power is AC, which is applied to the three anodes of the diodes. The anode of each diode is connected to its own phase of the AC power, allowing an equal amount of current to flow through each of the diodes. Due to the forward voltage of the diodes, only current in the same direction (forward current) will pass through the module.

The output of the FST31180 module is DC, and is provided through the cathode of each of the three diodes. Each diode in the module is capable of providing a maximum instantaneous current of 800A, with a rated maximum surge of 1,000A per diode. The forward voltage of the diodes limits the maximum voltage that can be applied to the module. The FST31180 module is protected by two PTC thermistors, which limit the inrush current and protect the module from high temperature conditions.

The FST31180 module can be integrated into a wide variety of applications, including power supplies, motor starters, and lighting control systems. The module can be used for controlling the flow of electric current in a wide range of devices, providing a high degree of thermal stability and power dissipation. As well, the module is protected by two independent PTC thermistors, allowing it to be used with confidence in demanding applications.
