TVS (Transient Voltage Suppression) Diodes, also known as Transient Voltage Surge Suppressors, are devices used to protect sensitive electronic components from high or low levels of voltage, referred to as transient overvoltage stress and/or electrical overstress (EOS). TVS diodes are commonly used in automotive, medical, industrial, and consumer electronic products, among others.

The MAPLAD18KP45AE3 is a TVS (Transient Voltage Suppression) Diode specifically designed to protect sensitive electronics from transient overvoltages in a variety of applications. It is an unidirectional diode, meaning it will only protect against transient overvoltage conditions, such as from a lightning strike or an electrical power fault, and will not protect against short circuit conditions.

The MAPLAD18KP45AE3 can be used in a variety of applications, including consumer electronic products, automotive electronics systems, telecommunications, medical equipment, and industrial equipment, among others. The diode is specifically designed to handle high-power-pulse applications and is also rated to handle up to 900 volts of reverse power surge peak current for a duration of 8 microseconds.

The core feature of the MAPLAD18KP45AE3 is its ability to clamp a voltage very quickly across a wide range of temperatures. This is done through its construction using patented advanced laser doping technology, which enables devices with low dynamic resistance and fast clamping response time. The diode is also designed with high thermal dissipation through thermal resistance and is resistant to high humidity. The MAPLAD18KP45AE3 also has a lower operating temperature which helps it to withstand higher levels of transient overvoltage for a longer duration without damage.

The working principle of the MAPLAD18KP45AE3 is based on avalanche breakdown. The avalanche breakdown occurs when the voltage across the junction exceeds the rating of the diode, resulting in an avalanche of electrons and holes that cause a current surge. The magnitude of the current surge is determined by the breakdown voltage of the junction, which is usually set at a value below the normal operating voltage so as to not damage the device. When the voltage across the junction reaches this value, the diode is triggered into avalanche breakdown and a current surge occurs, which is also known as the clamping voltage.

When the voltage across the junction returns below the breakdown voltage, the avalanche breakdown ends and the voltage across the junction returns to its normal operating level. The MAPLAD18KP45AE3 is designed with a low-impedance path, which allows for a significant reduction in the clamp voltage level and guaranteed zener action.

The MAPLAD18KP45AE3TVS diode is a useful and reliable device for a variety of applications, and its ability to quickly clamp transient overvoltages makes it ideal for high-power-pulse applications and applications in environments that are susceptible to high levels of transient overvoltages. This diode is a great choice for consumers, automotive, medical, and industrial applications.
