TVS - Diodes: PTVS20VP1UTP,115 Application Field and Working Principle

The PTVS20VP1UTP,115 is a type of Transient Voltage Suppression (TVS) diode designed specifically for protecting sensitive electronic equipment from possible damages due to transient voltage surges. TVS diodes, with their sensitive capacity to detect and suppress sudden and abnormal increase of voltage, have become increasingly popular and important in today’s electronic industry. This article will discuss the PTVS20VP1UTP,115 TVS diode, its application field, and its working principle.

Overview

The PTVS20VP1UTP,115 is a type of bidirectional TVS diode which contains no internal circuitry. The device is small in size, making it suitable for surface-mount technology (SMT). Its reverse leakage current is low, imparting excellent reliability to the device. The device also features robust surge capability and low parasitic capacitance. All these features make the PTVS20VP1UTP,115 suitable for a wide range of applications.

Application Field

The PTVS20VP1UTP,115 is widely used in areas that require protection against voltage transients. Such applications include telecommunications equipment, computers, data storage systems, power measuring systems, and building automation systems. This TVS diode is also used to protect different types of electronic components such as relays and gas discharge tubes.

Working Principle

The PTVS20VP1UTP,115 utilizes a unique design where two diodes are connected back-to-back, forming a bidirectional “sandwich” configuration. When a voltage surge occurs, the diode will start conducting and the charge is discharged as quickly as possible, thereby limiting the voltage rise on the system.The working principle of the PTVS20VP1UTP,115 is simple yet effective. When the surge voltage reaches the breakdown voltage rating of the device, the amount of current through it increases. This increase of current causes a large, rapid voltage drop in the device, limiting the voltage rise of the system. This is done without the need to use any external circuitry or components.The PTVS20VP1UTP,115 provides high-performance surge protection for sensitive electronic equipment. Its small size and low parasitic capacitance contribute to its performance, allowing it to be used in a wide variety of applications. The device also features robust surge capability and low reverse leakage current, making it an excellent choice for surge protection.
