All these features make VS-UFB80FA60 ideal for power converters, battery chargers, DC/DC converters, UPS systems, etc. It also has a very high surge capacities of up to 1000A making it well suited for high current applications such as wind power turbine systems, electric vehicle charger, etc.

Working Principle of VS-UFB80FA60

The VS-UFB80FA60 Diode Rectifier Array consists of 8 bridge rectifiers arranged in a bridge rectifier topology. It is designed with a pin layout of 4 pins per phase which allows it to be interconnectable with other components. Each phase of the rectifier contains two diodes which are arranged in anti-parallel manner. The diodes are placed in such a way that the positive and negative currents are passed through the same diode in the same direction. When the input voltage is applied to the device, the diodes become forward biased and current starts flowing through it. The current from each phase is combined to make up a single high power output.

VS-UFB80FA60 is equipped with an integrated protection circuit which prevents the device from damage due to transient over-voltage. This protection circuit consists of the following components of a Transient Voltage Suppressor diode, a P-channel MOSFET and a clamping circuit. The P-channel MOSFET is responsible for controlling the output voltage. When the input voltage goes above its rated limits, the P-channel MOSFET turns on and the clamping circuit clamps the output voltage at a set level. In addition to this, the transient voltage suppressor diode also acts as a switch to redirect the excessive current away from the device.

VS-UFB80FA60 diode rectifier array is designed to provide a wide operating temperature range, high efficiency, and very low forward voltage drop. It is an ideal solution for very high power applications such as solar PV and electric vehicle charger. The very low gate capacitance and low switching noise makes it suitable for many power conversion applications. The integrated protection circuit ensures the device against transient over-voltages and thus increase its reliability.
