Working Principle of VS-15CTQ035SPBF

The working principle of VS-15CTQ035SPBF is based on Schottky barrier diodes. It consists of two metal plates on opposing sides of a semiconductor material. The metal plates are connected to the anode and cathode, respectively. When the diode is forward biased, the applied voltage builds up a potential barrier at the metal-semiconductor interface, which reduces the forward bias current and prevents the flow of electrons from the anode to the cathode. This reduces forward power loss and increases the efficiency of the array. When the applied voltage is in the reverse direction, the majority carriers in the semiconductor material, holes and electrons, will cross the Schottky barrier and recombine with each other, resulting in zero current flow. This is how the diode array can be used to rectify AC current and provide low voltage DC power with high efficiency.

Conclusion

VS-15CTQ035SPBF is a type of 15A Schottky barrier rectifier array manufactured by Vicor Corporation. Its characteristics of low forward voltage drop, low reverse leakage and high surge current capability make it suitable for many applications in the field of power electronics. The working principle of the array is based on Schottky barrier diodes. When forward biased, it reduces the forward bias current and helps to reduce the power loss.
