TVS - Diodes

A Transient Voltage Suppressor (TVS) diode is a special type of diode designed to protect integrated circuits (ICs), electrical components, and sensitive electronic equipment from high-power electrical transients or surges. As a type of surge-protective device, it is designed to limit the surge voltage and prevent it from propagating further downstream. The working principle of TVS diode refers to its ability to detect and divert surge voltage away from the protected circuit.

D1213A-01LPQ-7B Appliation Field and Working Principle

The D1213A-01LPQ-7B is a unidirectional TVS diode with a 5.0V Breakdown Reverse Voltage. This device also offers a 350A peak pulse current, 10/1000μsec surge pulse times and a fast reverse recovery time. It has a unidirectional polarity, which means it only allows electricity to flow in one direction. All these features make the D1213A-01LPQ-7B suitable for a wide range of applications, such as computers, smartphones, power supplies, and automotive equipment.

The working principle of the D1213A-01LPQ-7B is similar to that of any other TVS diode. This diode is designed to detect surges in voltage by sensing an increase in voltage. When the voltage surpasses the diode\'s breakdown voltage (5V in the case of the D1213A-01LPQ-7B), the diode begins to conduct. The current then travels through the diode and into a low resistance path, which dissipates the energy and prevents the surge from propagating downstream. This protects the circuit from overvoltage and prevents any damage it may cause.

The fast recovery time of the D1213A-01LPQ-7B ensures that it can respond quickly to a surge and divert it away from the protected circuit. The 350A peak pulse current makes it suitable for heavier loads, while the 10/1000μsec surge pulse times mean it can detect even fast transients. All of these features make the D1213A-01LPQ-7B a reliable surge protector for a variety of applications.

The D1213A-01LPQ-7B is an ideal TVS diode for applications that need reliable surge protection from high-power electrical transients. Its wide range of features and working principle make it suitable for use in computers, smartphones, power supplies, and automotive equipment, among other applications.
