Thyristors, or silicon-controlled rectifiers (SCRs), are a type of thyristor switch designed to control the flow of electrical power. The 2N4368 is one of the most commonly used devices in this type of technology, and is known for being fairly reliable and cost-efficient. In this article, we’ll examine the 2N4368 application field and working principle.

The 2N4368 is primarily used as an AC switch for applications such as switching between phases in an AC voltage system or in an AC inverter. It can handle currents of up to 400 amps and voltages of up to 800V. This makes it a popular choice for many industrial applications, such as welding and power conversion.

The 2N4368 is a three-terminal device consisting of a gate, an anode, and a cathode. The device works on the principle of a thyristor switch. That is, when voltage is applied to the gate and cathode terminals, the device remains in the off state until the anode voltage reaches the minimum breakover voltage. Once this threshold is reached, a current of up to 400 amps can flow through the device.

The 2N4368 has a wide range of application areas, and is used in a variety of commercial and industrial products. For example, it is commonly used in motor drives, rectifiers, and inverters. It is also used in high-voltage switches and power supplies, as well as in medical equipment.

As for the working principle of the 2N4368, it relies on a process known as minority carrier injection. When the device is in the off state, the gate-to-cathode voltage is less than the minimum breakover voltage. This prevents the device from conducting current. When the gate-to-cathode voltage is increased to a certain level, minority carriers are injected from the gate and cathode, which then trigger the breakover voltage and allow current to flow.

The 2N4368 is also relatively easy to use and maintain. It is capable of withstanding short-duration electrical overloads and overheating, and its operating temperature can range from -55°C to 175°C. The device is also capable of withstanding voltage transients and surges, making it a reliable and cost-efficient choice.

Overall, the 2N4368 is a versatile and reliable device and is widely used in a variety of industrial, commercial, and medical applications. Its wide operating temperature range, overload capability, and voltage transient capability make it a popular choice for many applications. Its ability to handle currents of up to 400 amps and voltages of up to 800V make it ideal for a wide range of industrial applications requiring high levels of power.
