TVS (transient voltage suppressors) - Diodes are very useful devices in power management applications. The SMBJ200AE3/TR13 is a particularly useful device in this regard, as it can be used for simultaneous protection of both high- and low-voltage systems. In this article, we will take a closer look at the application fields and working principles of the SMBJ200AE3/TR13.

The SMBJ200AE3/TR13 provides transient protection for medium-power systems in a wide range of industrial and consumer electronics applications. It is an unidirectional 150W low-capacitance transient voltage suppressor (TVS) that can protect against overvoltage spikes of up to 800 V. The device also protects against reverse-polarity surge conduction and ESD protection per IEC 61000-4-2. It offers better protection to the equipment from the hazards of overvoltage transients.

One of the main advantages of the SMBJ200AE3/TR13 is its very small form factor, which makes it suitable for a wide variety of applications. In addition, the device offers excellent thermal stability and wide operating temperature range, up to +125°C. This allows it to perform reliably in harsh environments, making it suitable for use in industrial equipment.

In terms of how the device works, the SMBJ200AE3/TR13 has a breakdown voltage of about 200 V, which is the voltage at which the TVS diode will become conductive. When the voltage applied to the device drops below the breakdown voltage, the device will switch to a low-impedance state and allow current to flow through it. This current will be redirected away from the sensitive components of the circuit, resulting in protection from over-voltage transients.

The SMBJ200AE3/TR13 is also capable of dissipating excess energy during surge events, thanks to its large thermal dissipation capability. This ability to dissipate energy helps protect the device and connected components from damage caused by repetitive overvoltage conditions. In addition, the device also offers excellent ESD protection performance, making it suitable for a wide range of applications.

The SMBJ200AE3/TR13 can be used in a variety of situations where it is necessary to provide transient protection. This includes power management applications such as automobiles, medical equipment, consumer electronics, and other sensitive electronics systems. In these types of applications, the device helps to provide protection to the circuitry from the hazards of overvoltage transients.

In summary, the SMBJ200AE3/TR13 is a very useful TVS diode in power management applications. It is capable of providing excellent transient protection, thanks to its breakdown voltage of 200 V and large thermal dissipation capabilities. Furthermore, the device is also capable of providing effective ESD protection, making it suitable for a wide range of applications. The device’s small form factor and wide operating temperature range also make it suitable for a wide variety of situations.
