Transient voltage suppressors (TVS) diodes are an electronic device designed to protect sensitive electronics from high voltage transient pulses, usually resulting from electrostatic discharge (ESD). The TVS diode was invented in the early 1960s to shield electronic circuits from high voltage pulsed transients such as ESD, lightning, and other transients. The most common type of TVS diode is the PTVS14VS1UR,115. PTVS14VS1UR,115 is a bidirectional TVS diode that is capable of suppressing transient voltages from both positive and negative polarity. The device has an avalanche breakdown voltage of 14 volts and a peak pulse power rating of 1,000 watts, making it ideal for a wide range of applications. This article will provide an overview of the application fields and working principle of the PTVS14VS1UR,115.

The PTVS14VS1UR,115 is commonly used in telecom and networking equipment where space, cost, and reliability are of the utmost importance. The device can be used in both network and voice services for over-current and over-voltage protection, as well as ESD protection. It can also be used in automotive applications such as over-voltage protection for ECUs and Bluetooth modules. In industrial applications, it is often used to protect circuit boards and other components from high-current transients, electrical shorts, and over-voltage spikes.

The structure of the PTVS14VS1UR,115 is a standard axial reverse parallel (series) diode structure. The diode has two anode and two cathode electrodes connected in parallel with a reverse breakdown voltage of 14V. The structure of the diode is designed to allow the device to handle large transient pulses without sustaining any permanent damage. The device also incorporates a patented Soft-Ramp technology that ensures a low let-through voltage. This helps the device to absorb the energy from the transient pulses while still preventing the voltage on the connected circuitry from exceeding a certain level.

The working principle of the PTVS14VS1UR,115 is based on the avalanche breakdown effect. When a high voltage signal reaches the reverse breakdown voltage of the device, the diode enters an avalanche breakdown state. At this point, the diode begins to conduct a large amount of current, which is then dissipated as heat through the diode’s external heat sink. This process quickly discharges the transient voltage pulse, thus protecting the connected circuitry.

The PTVS14VS1UR,115 is a highly reliable bidirectional TVS diode that is ideal for a wide range of applications in both telecom and automotive applications. It is capable of suppressing transient voltages from both positive and negative polarity, with an avalanche breakdown voltage of 14V and a peak pulse power rating of 1,000W. The device utilizes a patented Soft-Ramp technology to ensure low let-through voltage, and utilizes an avalanche breakdown effect to discharge transient voltage pulses. The device is highly reliable and offers a high level of protection for sensitive electronic equipment.
