Diodes - Rectifiers - Arrays

The 30CTQ035S is an ultra-fast, 35.4 ampere, 800V Schottky power rectifier. It is primarily used in rectifying alternating current (AC) signals and is one of the most popular and widely used power rectifiers in the market. Schottky rectifiers have a faster and more responsive rectifying function compared to other rectifiers.

The 30CTQ035S is available in a TO-220F package with industry standard pin out, which allows for easy integration into existing power supply applications. It has high current and voltage capabilities, making it ideal for applications that require a powerful, efficient rectifier, such as in AC/DC converters and power conditioners. The 30CTQ035S features a low forward voltage drop, making it more efficient than most other rectifier diodes.

The 30CTQ035S is commonly used in applications such as motor controls, inverters, regulated power supplies and voltage regulators. Its design enables low losses and long-term reliability. It is also widely used in AC applications such as switching power supplies, zero crossing detectors, and power factor controllers.

Working Principle

The 30CTQ035S works by converting alternating current (AC) into direct current (DC) signals. It is a two-terminal device that works by allowing electric current to flow in one direction only from the anode to the cathode. The current passes through a Schottky barrier, a thin semiconductor layer with a highly doped p-n junction. This barrier decreases forward voltage drop and increases the speed of rectification.

When the anode voltage is greater than the cathode voltage, electric current flows through the Schottky barrier and an external load. The electric current can flow in this direction with no resistance more as long as the external load is not connected. When an external load is connected, the electric current must cross a resistive node, which produces a small voltage drop. This voltage drop is the forward voltage drop commonly referred to in diode applications, and the amount of the drop is mainly determined by temperature.

The 30CTQ035S has a reverse voltage blocking capability of up to 800V, meaning it prevents current flow in the opposite direction of the anode to the cathode. This is useful in AC applications such as AC/DC converters, voltage regulators, and power conditioners where a fast response is required.

Conclusion

The 30CTQ035S is an ultra-fast, 35.4 ampere, 800V Schottky power rectifier. It is primarily used in AC applications such as motor controls, inverters, and regulators, as well as switching power supplies and zero crossing detectors. It features a low forward voltage drop, making it more efficient than most other rectifier diodes. The 30CTQ035S works by allowing current to flow in one direction only while blocking flow in the opposite direction.
