Thyristors are an important type of semiconductor component that are usually used in power control and power conversion. The TB1800L-13 is a powerful but small thyristor that is mainly used in the automotive, industrial, and medical fields. It has a low on-state voltage drop and excellent avalanche capability, which makes it an ideal device for power supply applications.

The TB1800L-13 utilizes a unique thyristor architecture, which is composed of two parallel floating thyristors connected in series. This thyristor architecture provides high current conduction capabilities and high voltage ratings. This makes the device useful for power control applications in a variety of applications such as motor drives, solar inverters, industrial lighting, and power supplies.

The TB1800L-13 has a triggering voltage of 283V and a blocking voltage of 600V. It also has an on-state voltage drop of 1V and an avalanche current of 35A. It has a high current gain of 0.9V/A and a di/dt of 1000A/us. The device is also designed with a built-in thermal protection which prevents its over-temperature in harsh environmental conditions.

The working principle of the TB1800L-13 is simple. The two parallel thyristors are connected in series to form a closed loop circuit. When a voltage is applied to the input terminals, a current is generated in the circuit and the thyristor switches on. The voltage across the thyristor is maintained until the current decreases to zero or until an external device turns it off. The device remains in its off state until the current passes through it again.

The TB1800L-13 is an ideal device for use in a variety of power control applications. Its rugged construction makes it suitable for use in harsh environments, and its low on-state voltage drop and excellent avalanche capability makes it ideal for use in motor control and power supplies. The device is also designed with a built-in thermal protection feature which prevents it from over-temperature in harsh environmental conditions.
