TVS - Thyristors: TVB190MSC-L Application Field and Working PrincipleThyristors, or Silicon Controlled Rectifiers (SCRs), are a type of electronic switching device used in a wide range of voltage control applications such as power electronic systems. TVB190MSC-L is a type of Thyristor made by TVS (Thyristor Corporation). This article will discuss the application field and working principle of TVB190MSC-L. Application Field of TVB190MSC-LTVB190MSC-L can be applied for controlling AC or DC power in any environment, including industrial, consumer and automotive. The main application areas include:

• Electronic powere voltage regulators (VDRs) for power conditioning and frequency conversion.
• High-power control in motor drives in automation such as electric vehicles.
• Solar energy systems for controlling large currents of solar panels.
• Air Conditioners, Refrigerators, Freezers and other electrical appliances.
• Smart grid systems and power distribution.
• Lighting control.

TVB190MSC-L also features high voltage breakdown capability (up to 900V) and high leakage current (50mA). It can also handle transients of up to 6kV and pulses of up to 12A.Working Principle of TVB190MSC-LTVB190MSC-L consists of an anode and a cathode, separated by a layer of PN junction. When the breakdown voltage is applied between the anode and the cathode, the N-doped region below the anode attracts the minority carriers due to its electric field. A space charge zone is created and the voltage drops across this zone.The forward current is controlled by a gate. The gate can supply a positive charge and the voltage is applied across the gate-cathode junction. The applied voltage increases the forward current and the voltage drop across the PN junction increases. This increases the %ON state of the thyristor and the device is turned on.Once the TVB190MSC-L is on, the device keeps conducting until the current falls below a certain value or if the gate voltage becomes negative. This causes the device to turn off. ConclusionTVB190MSC-L is a type of Thyristor made by TVS. It can be applied in multiple electronics and power control applications such as power conditioning, motor drives, solar energy, air conditioners and smart grids. Its working principle is based on forward current control via a gate voltage.
