Introduction

RU 4Z is a four-terminal rectifier which is widely used in power supply, which can efficiently reduce the ripple voltage. This device is mainly classified as Diodes - Rectifiers - Single, and also belongs to Sensitive gate rectifier. This article is going to discuss the application field and the working principle of the RU 4Z.

What is RU 4Z?

RU 4Z is a four-terminal rectifier diode, available in power semiconductor packages with glass-encapsulated junctions and with four terminals, two anodes and two cathodes. It is mainly used in power supply circuits to reduce the ripple voltage and improve the switching speed.

Application Field of RU 4Z

RU 4Zs are widely used in many application fields. They are mainly used in the power supply, because they can reduce the ripple voltage and improve the switching speed. For example, they can be used in automobile interior lighting or automotive electronics. Besides, they can also be used in robotics and automation, communication, home appliance and other industrial applications.

Working Principle of RU 4Z

The working principle of RU 4Z is based on the principle of a thyristor. It consists of two electrodes (anode and cathode) and two control electrodes (gate and cathode). It has voltage regulating characteristics, and the forward voltage drop across the two electrodes is determined by the gate-cathode voltage. When the gate-cathode voltage is low, the forward voltage drop will be low, and the conducting current will be large. At the same time, the reverse voltage drop across the two electrodes will also be large.In addition, the RU 4Z can also be used in resonant circuits, because it can regulate the voltage drop in both directions. The forward voltage drop can be used to control the resonant frequency, while the reverse voltage drop can be used to reduce the current through the device. This makes the RU 4Z useful in power supplies, because it can reduce the ripple voltage.

Conclusion

RU 4Z is a four-terminal rectifier which is widely used in power supply. It is classified as Diodes - Rectifiers - Single and belongs to Sensitive gate rectifier. It can reduce the ripple voltage and improve the switching speed. It is mainly used in power supply, automobile interior lighting or automotive electronics, robotics and automation, communication, home appliance and other industrial applications. The working principle is based on the principle of a thyristor.
