Working Principle

The SDT20B100CT utilizes a dual common anode Schottky diode array in its design. The array is made up of two separate anode connections and two separate cathode connections. The two anode connections are connected to a central common node and the two cathode connections are connected to an external circuit. When operated, the Schottky diodes act as rectifiers, meaning that current will only flow in one direction, allowing the rectifier array to be used in AC and DC applications.

The common connection of the anodes acts as the input while the two separate connections act as the outputs. The voltage between the two outputs will be half the input voltage. When current passes through the common node, it can be transmitted through the two separate anode connections and out the two cathode connections in the same direction. This allows the SDT20B100CT to be used as a rectifier that can reduce the voltage of incoming AC power.

Conclusion

The SDT20B100CT Rectifier Array is a versatile device with many applications. It is a low forward voltage drop dual common anode reverse Polarity Schottky Diode Array that is able to handle large currents and reverse voltage blocking capabilities. It is suitable for use in a variety of applications, from high frequency rectification to automotive electronics.
