Overview of SMAJ180E3/TR13

The SMAJ180E3/TR13 is a kind of Transient Voltage Suppression Diode (TVS) or commonly known as a Transient Voltage Suppressor (TVS). This kind of TVS device is a three-terminal unidirectional +/- 18V type that is used in a broad range of applications. This device is able to reduce and control the spike or surge in the transient voltage that is present in a power line or circuit. It works by conducting the excess current flow that comes from the transient voltage.

Application Field of SMAJ180E3/TR13

The SMAJ180E3/TR13 is a useful TVS device in many different kinds of application areas. It is widely used in different kinds of telecommunications equipment including computers, modems, fax machines, and telephone networks. It is also specifically designed to be used in automotive electronics, such as control systems, entertainment systems, and engine control systems. Long‐distance or mobile communication systems, such as satellite TV or a cellular phone base station, may also utilize the SMAJ180E3/TR13’s protection capabilities.

Working Principle of SMAJ180E3/TR13

The SMAJ180E3/TR13 works by utilizing a combination of avalanche breakdown and temperature-dependent nonlinearities. The device has a Zener breakdown of 18V and a dynamic discharge time of about 50ns. When the applied voltage exceeds 18V, it will cause an avalanche breakdown in the PN junction, which will result in a large amount of current flow. This current will quickly discharge the transient voltage and provide an efficient protection.In addition, the device is able to handle a wide range of temperature with its excellent thermal stability. It provides superior temperature-independent operation that is highly beneficial for many kinds of audio, video, and data transmission applications.Overall, the SMAJ180E3/TR13 Transient Voltage Suppression Diode is an ideal protective solution for many different kinds of applications that handle high-voltage transients. It is able to provide a high level of voltage protection while still maintaining its wide working temperature range.
