TVS diodes, also known as transient voltage suppressor, are the most commonly used form of overvoltage protection circuit among many different circuit protection solutions. SMDB03/TR13 is a a sub-category of TVS diodes, and is more popularly used in modern high-speed circuit protection. The application field and working principle of SMDB03/TR13 are described below.

Application Fields

SMDB03/TR13 TVS diodes are mainly used in high-speed data interfaces, including telecommunications, computers, data storage, wireless communications, power electronics, and automobiles. The basic purpose of using this type of diode is to protect electronic circuits against surge voltages and transients. The typical voltages these diodes can protect and the transient length they can protect against are typically around 600V and 500us respectively. These diodes are designed to withstand up to three thousand watts of power, making them a reliable, cost-effective, and efficient solution for controlling surge voltages and transients.

Working Principle

SMDB03/TR13 TVS diodes are designed to short the voltage surge and clamp the transient to a safe operating voltage level. This works by allowing the current to pass from the anode side to the cathode side. When a surge is detected, the diode switches to the forward conduction mode and shorts the surge. This increases the resistance and reduces the voltage. The process is repeated as the surge passes through the diode until the voltage is dissipated to the safe voltage level.

These diodes can also be used to provide a surge response rate that is much faster than other types of TVS diodes. This is due to the use of semiconductor materials that can respond very quickly to voltage transients with low on-state resistance. This low resistance enables the diode to reduce the surge voltage in a shorter amount of time, thus making them more effective at protecting sensitive electronics.

SMDB03/TR13 TVS diodes are a highly reliable form of overvoltage protection circuit, and their popularity is steadily growing. Their fast response rate, low on-state resistance, and high power handling capabilities make them a great choice for many applications where surge and transient protection is needed.
