TVS - Thyristors: P2202ABL Application Field and Working Principle

Thyristors, also known as silicon controlled rectifiers (SCRs), are widely used electrical components in a variety of applications across numerous industries. A type of thyristor that has recently become popular is the P2202ABL from STMicroelectronics, which is designed to provide fast switching and bidirectional transient voltage and current protection. The P2202ABL can be used in a variety of applications, including power management, lighting, consumer electronics, automotive, and industrial systems. This article will discuss the applications and working principle of the P2202ABL thyristor.The P2202ABL thyristor is designed to provide a bidirectional transient voltage and current protection that is fast and highly robust. This means that it is capable of protecting LED and automotive applications that are dependent on highly efficient and cost-effective power conversion. It also provides low power losses and can handle up to 200A surge and 40V clamping voltage.The P2202ABL has an on-state voltage drop of 0.2V, which is significantly lower than other thyristors, and it has a typical breakdown voltage (Vbr) of 80V. This low breakdown voltage makes it suitable for applications in which the user needs to maintain a low voltage. Additionally, it has a high-temperature operating capability (-55 to 150°C) that allows it to be used in applications that require extreme temperature ranges.The P2202ABL is a unidirectional thyristor, which means that current will only flow in one direction through it. It has a typical latching current of 3A, and a operating current of 8A. The device also features a gate-to-cathode triggering voltage of 4.5V.In order to understand how the P2202ABL thyristor works, it is important to understand the basic principles of a thyristor. A thyristor is a type of solid-state switch that is used to control current and voltage in a circuit. It consists of four alternating layers of N-type and P-type semiconductor material. When the gate voltage of the device is increased to the “on” level, a current flows through the device and the device is in the on-state. When the voltage is decreased to the “off” level, the device is in the off-state and no current flows.The P2202ABL is designed to provide fast response times, with typical latching times of around 400ns. This makes it suitable for use in applications that require fast switching. Additionally, it is capable of providing protection from overvoltage transient spikes that are typically present in automotive applications.In conclusion, the P2202ABL thyristor is designed to provide fast on/off switching, high temperature range capability, low on-state voltage drop, and a high current capability. It is suitable for a wide range of applications, including power management, lighting, consumer electronics, automotive, and industrial systems. Its low latching current of 3A and its 4.5V gate-to-cathode triggering voltage make it suitable for applications in which the user needs to maintain a low voltage.
