Surge Protective Diodes

Surge Protective Diodes

Surge protective diodes, also known as transient voltage suppressor diodes (TVS diodes), are electronic components designed to protect sensitive electronic devices from voltage spikes or surges. These voltage surges can occur due to lightning strikes, electrostatic discharge, or switching transients in power systems. Surge protective diodes work by clamping the voltage to a safe level, preventing the voltage from exceeding the maximum voltage rating of the protected device. Surge protective diodes are made of semiconductor materials such as silicon or germanium and are designed to operate in reverse-bias mode. When a voltage surge occurs, the diode conducts current in the reverse direction, limiting the voltage across the protected device. The surge protective diode is designed to have a low breakdown voltage, which means that it will start conducting at a voltage slightly above the normal operating voltage of the protected device. This ensures that the voltage across the protected device does not exceed its maximum rating. Surge protective diodes are commonly used in electronic devices such as computers, telecommunication equipment, and power supplies. They are also used in industrial and automotive applications to protect sensitive electronic components from voltage surges. Surge protective diodes are available in a variety of packages, including surface mount and through-hole packages, and can be easily integrated into electronic circuits. In summary, surge protective diodes are electronic components designed to protect sensitive electronic devices from voltage surges or spikes. They work by clamping the voltage to a safe level, preventing the voltage from exceeding the maximum voltage rating of the protected device. Surge protective diodes are commonly used in electronic devices and are available in a variety of packages.
