A reverse-blocking thyristor (RU 4M) is a four-layer diode-like thyristor constructed with two PN-junction which works in reverse blocking mode. The RUs 4M is mainly used in electronic circuits for a range of applications, such as rectification, voltage regulation, and motor control. An RU 4M consists of two PN junction pair connected in opposite direction. It is specially designed to block any current flow from the anode to the cathode. This feature gives it the name reverse-blocking thyristor.

The RU 4M is widely used in switching and controlling circuit, particularly in application where a low voltage to high voltage is required. These applications include dc/ac converters, power supplies, inverters, pulse generators, motor controllers, and protection circuits. There are three main components that form the RU 4M: the anode, the cathode, and the gate. The anode is the part that receives a voltage and allows current flow. The cathode is the part where the current returns to the source. The gate is the part that controls and triggers the switching of the RU 4M.

One of the main advantages of an RU 4M is its reverse blocking mode. This allows for greater current control in a circuit by preventing current from flowing from the anode to the cathode. This mode also helps to protect the circuit from over-voltages and short-circuiting. The RU 4M also has a high surge rating, allowing it to be used in high voltage switching applications.

The working principle of an RU 4M is quite simple. When a voltage is applied to the anode, it allows current to flow from the anode to the cathode. The voltage of the anode must be higher than the cathode in order to allow the current to flow. When the voltage on the anode is equal to the voltage on the cathode, the RU 4M is in the reverse blocking mode and no current can pass through.

In order to turn on the RU 4M, an additional voltage must be applied to the gate. This triggers the PN junction, which in turn allows the current to flow from the anode to the cathode. The turn-off of the RU 4M is usually achieved by momentarily reversing the voltage or removing the gate voltage.

RU 4Ms are reliable, durable, and cost-effective devices used in a wide range of applications. They are typically low power consumption, fast switching, and finger-safe devices which are available in a variety of package styles for easy integration into existing systems. With its reverse-blocking mode, the RU 4M can be used in a variety of applications, ranging from protection circuitry to rectification and voltage regulation.
