TVS - Thyristors

Thyristors are a class of solid-state semiconductors designed for the switching and control of electrical signals. They are highly reliable and can endure extreme temperatures and high electrical currents with minimal degradation. They are frequently used in industrial and consumer applications, such as motor controllers, voltage regulation, and other power management systems. Thyristors are also used in the automotive industry, as light dimmers and starters, and for signal transmission control.

P0720Q22CLRP Application Field

The P0720Q22CLRP is an ultra-compact, high efficiency, and cost-effective thyristor suitable for power switching applications where compactness and high voltage are critical considerations. This thyristor is designed to be used in a wide range of applications, from consumer electronics to industrial machinery. It can be used in motor controller applications, light dimmer applications, solid state relay applications, power supply applications, power controllers, instrumentation power management, and voltage regulation circuits. The P0720Q22CLRP is also suitable for use in automotive power control applications, where its high surge capability and fast switching capability make it a good fit for applications such as headlights and taillight dimming.

P0720Q22CLRP Working Principle

The P0720Q22CLRP thyristor is designed to operate in two fundamental modes: on/off and unidirectional. The thyristor is built from three basic semiconductor layers: a Control Terminal (CT), a Control Gate (CG), and an Anode (A). The two back-to-back junctions form a PNPN structure, which is essential for switching the main current. When the Control Terminal is at a certain potential, the P-N junction between the Control Gate and the Anode becomes forward-biased, allowing current to flow from the Control Gate to the Anode. The thyristor then switches on, and the current flows through its Control Gate to the anode and ends with the cathode. The thyristor turns off when the voltage across its Control Terminal drops below a certain value.

The P0720Q22CLRP controls the main current by the use of a gate terminal, enabling it to be turned on or off quickly and precisely. The control voltage is applied to the Control Gate and the Anode terminals, while the cathode is connected to the source of the main current. The gate terminal is isolated from the main current, allowing it to remain relatively unaffected by the fluctuations of the main current. The high surge capability of the device allows it to switch on and off quickly with minimal losses. The high frequency switching capability of the device makes it an ideal choice for applications such as dimming and switching of heavy electrical loads.
