TVS diodes, sometimes known as Transient Voltage Suppressor Diodes, are used in electronic applications to protect sensitive electronic components from voltage spikes that occur due to electrostatic discharges (ESD). As a result, they are commonly used in a variety of electronic products, from cell phones and microwaves to medical equipment and aviation systems. The SMDB05TR is an example of a TVS diode, designed for low ESD performance and a high-voltage breakdown capability.

The SMDB05TR diode is a bidirectional silicon triggering, zener diode that provides a very low leakage current and a low on-state resistance. It is designed for easy mounting and uses surface-mounted technology (SMT) that allows for fast and easy interception of the rising and falling voltage associated with a transient voltage surge. It can easily be integrated into a circuit and its operation is extremely reliable, with a reverse breakdown voltage of over 400V.

The SMDB05TR\'s application field can be divided into three main areas: protection against ESD, direct applications and reverse ESD protection. In terms of ESD applications, the SMDB05TR is very useful for low-voltage applications, where the voltage of the transient surge may exceed the limits of the electronic device or circuit. The excellent ESD protection makes it ideal for use in electronic devices that are prone to environmental extremes, such as laptops, tablets and cell phones. For direct applications, the diode is ideal for protecting receivers and active components, as it prevents transients from reaching its gate and operating voltage.

Finally, in terms of reverse ESD protection, the SMDB05TR is most useful when used in conjunction with a shunt regulator. This combination allows for extra protection beyond the traditional ESD limits and makes it easier to protect against voltage transients associated with high ESD pulses.

The working principle of the SMDB05TR diode is simple and straightforward. The diode itself is incredibly small but is capable of extremely precise voltage regulation. It works by allowing a small current to flow through it until a specified breakdown voltage is reached. At this point, the internal impedance suddenly increases, allowing the surge current to travel through the diode and away from the sensitive electronics.

The SMDB05TR diode is a reliable and effective solution for protecting electronic components from high voltage transients. It has a wide range of applications in a variety of electronic devices and circuits, from consumer electronics to industrial machinery. It is particularly useful for low voltage applications, where traditional ESD protection levels may not be sufficient. Thanks to its accurate voltage regulation and low leakage current, the SMDB05TR diode is an excellent choice for reliable ESD protection.
