P0080SB Application Field and Working Principle

TVS - Thyristors

Thyristors, including thyratrons, are a type of solid-state switch that is commonly used within the electronics field. They are one of the most widely used components in today’s electronics and are typically found in applications such as power rectifiers, voltage regulators, periodical pulse generator circuits, and electric relays.One type of thyristor is the P0080SB, which is a type of symmetrical bidirectional SCR (Silicon Controlled Rectifier). This device is used as an electrical component and works as a switch that can allow current to pass in one or both directions and can be triggered or deactivated by an electrical signal. This is a very powerful and popular thyristor that is capable of controlling currents ranging from 500 to 1000 A with a reverse voltage from 800V up to 1000V.The driving principle of the P0080SB thyristor consists of two resistors and two diodes semiconductors, which are connected in parallel. The first resistor is known as a base resistor, which sets the base current and is used to adjust the firing angle of the thyristor. The second resistor is called the sense resistor and it controls the increase of the voltage across the load, thus controlling the phase angle of the circuit. The diodes are responsible for providing the necessary voltage over the thyristor and act as a protection to the thyristor from over current or voltage.The common application fields for the P0080SB include UPS systems, power supplies and motors, industrial heating systems, and light dimmers. Its strong currents and reverse voltage capabilities make it ideal for more industrial applications such as electric traction, welding machines, and static switch links.The P0080SB is a very powerful thyristor with the ability to control various electrical systems in both AC and DC applications. It is used in many industrial applications due to its strong current handling capabilities, reverse voltage ratings, and ability to prevent over current or voltage. This makes it an ideal choice for a wide variety of applications, from residential light dimmers to industrial heating systems. With its numerous advantages, the P0080SB is sure to remain a popular choice for thyristor manufacturers in the coming years.
