VS-12CTQ035PBF

Diodes - Rectifiers - Arrays

VS-12CTQ035PBF is an array of four integrated high-efficiency 35V, 12A schottky rectifiers in DFN5 package. It provides full-wave rectification with allowable power dissipation up to 3.2Ws and ultra low forward voltage drop with RMS forward current up to 12A. Due to its three pad packages and surfacemount technology, it provides enhanced thermal performance, enabling high-speed, high-efficiency applications in automotive, consumer, industrial and more applications.

Application Field and Working Principle

VS-12CTQ035PBF is widely used in battery management, power conversion, and power management systems. As an automotive rectifier, it is applied in off-line SMPS and battery chargers, as well as in various consumer, industrial, and communication power supplies. Under stringent efficiency requirements, VS-12CTQ035PBF provides superior rectification performance in four naturally opposing directions with very low forward voltage drop (VF) and a very low reverse leakage current (I-L). Its low forward voltage drop and leakage current enable higher efficiency and better temperature control.

VS-12CTQ035PBF array operates with a working principle similar to any other rectifier diode. Essentially, the rectifier diode will let the current of one direction flow through it and completely block the current of the opposite direction. In each direction, current is allowed to flow only if the anode of the diode is more positive than the cathode. When this condition is met, electrons move through the diode from the anode side to the cathode side, and holes move from the cathode side to the anode side. This movement is known as forward biasing, and the immediate application is rectification.

Since VS-12CTQ035PBF array is capable of featuring four such rectifying diodes, it is much more efficient than a single rectifying diode. It enables VS-12CTQ035PBF to have a better switch for current direction and increased reliability in terms of lower forward voltage drop, resulting in reduced power dissipation.

Conclusion

VS-12CTQ035PBF is suitable for applications where a reduced power dissipation or higher efficiencies are required. Its full-wave rectification helps to improve the outputs such as current and power. Due to its very low forward voltage drop this array also works great for low voltage applications. Its easy assembly, small size and high reliability make it suitable for applications in the automotive and consumer industry.
