TVS - Thyristors

P2202ACRP is a type of thyristor (Thyristor Voltage Suppressor, TVS) which is often used for surge protection in applications that require high performance, high speed and high levels of reliability such as automotive, aerospace, communication and medical markets. The device consists of a thyristor with two p-n junctions at the ends, which help to divert arc currents. The TVS can be used for protection against electrical overshoot, transient voltage spikes, lightning, and other electrical over-voltage surges that might be caused by electrostatic discharge or high-impedance sources.

Working Principle

The main working principle of P2202ACRP is the use of its two p-n junctions to divert arcs during over-voltage and current surges, as surge energy is generally higher than the junction breakdown voltage. The two junctions are connected in series, so when an arc event occurs between the two junctions, it is diverted and discharged externally. This reduces the exposure of the device’s internal components to an overload, as the arc current is absorbed in the external circuit. The other main feature is the inherent speed of response, which is much faster than the typical turn-on times for other protection devices, and therefore helps to protect against transients and lightning-induced surges.

Application Field

P2202ACRP are often used for protection against electrical overshoot, transient voltage spikes, lightning, and other electrical over-voltage surges. Applications that require high performance, high speed, and high levels of reliability, such as automotive, aerospace, communication, and medical markets, tend to benefit the most from the use of these thyristor devices.

The device is also used in a wide range of consumer electronics, such as televisions, home theater systems, and cell phones. The surge protection provided by these thyristors prevents electrical damage to the delicate circuits and components within the device, helping to ensure that the devices last longer and operate more reliably. Additionally, the device can be used in industrial and commercial applications, such as surge protection for electrical motors and other machines.
