Thyristors, also commonly referred to as silicon-controlled rectifiers (SCRs), are solid-state components that allow current to flow when a certain voltage is applied across their terminals. TVB190NSC-L thyristors are designed to meet the needs of industrial, railway, and military applications.

The TVB190NSC-L series of thyristors are reverse-conducting SCRs and possess two-wire control. This series combines a reverse blocking voltage rating from 1.2 to 1800V with a forward current rating of 1A or 2A. The TVB190NSC-L also features an ability to handle surge current of up to 10A. It can also be used in either half-controlled or full-controlled conduction applications.

In half-controlled applications, during the off period of the thyristor, no current flows in the output. When the thyristor reaches a certain voltage, the switch turns on and current flows. When the current reaches a particular level, the thyristor will turn off. The same process is then repeated.

In full-controlled applications, the current reaches a certain current level and the thyristor switches off. At this point the thyristor will not switch back on until the current drops to a predetermined level. This switching off process will continue until the thyristor reaches a particular voltage, at which point the thyristor will switch on and allow the current to flow back to the predetermined level.

The TVB190NSC-L, being reverse-conducting, can rapidly charge and discharge circuits, and is well suited for a range of power supply and energy management tasks such as dynamic braking, soft-start motors, voltage regulation, and power factor correction. It is also suitable for applications in renewable energy systems such as solar power and wind energy. The TVB190NSC-L can also be used in motors, inverters, thrusters, and high-current, low-voltage pulse applications.

The main feature of the TVB190NSC-L thyristor is its ability to handle high power loads while maintaining a low thermal profile. As a reverse-conducting thyristor, it is able to switch much more quickly than one with a forward conduction voltage. This speed is important in applications that require a fast response to input changes.

The TVB190NSC-L thyristor is also designed to have a wide operating temperature range. This makes it suitable for both heavy-duty industrial applications as well as applications that require a lighter duty cycle. The TVB190NSC-L\'s thermal profile ensures that it is protected against over-temperature conditions.

The TVB190NSC-L thyristor is designed to achieve high reliability and dependability in a variety of power control applications. Its features make it suitable for a wide range of industrial, railway, and military applications. Its ability to quickly charge and discharge circuits makes it an ideal component in power supply and energy management systems, as well as in motors, inverters, thrusters, and pulse applications.
