Transient voltage suppressors (TVS) are power semiconductor devices designed to protect electronic circuits from damage like electrostatic discharge (ESD) transient overvoltage and other electrical phenomena. As such, TVS diodes are essential components in the power supply and signal transmission design of all modern electronic systems like mobile phones, computers, and aircraft. TVS diodes function as a rectifier/control element, allowing current to flow only in one direction, and provide protection against voltage spikes and surges. The TPSMD18A is a typical type of TVS diode, used to protect sensitive electronic components from transient overvoltage.

The TPSMD18A is a unidirectional type of TVS diode and is primarily used to protect sensitive electronic components from transient overvoltage conditions, ensuring greater safety and reliability in their operation. It is designed for surface mount applications, with a low profile of 1.5mm maximum height, and occupies little space on the PCB. This allows the device to be used in compact power supplies, AC power adapters, and other space-constrained applications. The device has an excellent surge capability and is compliant with the IEC61000 and IEC61058 standards.The TPSMD18A diode can handle a maximum peak pulse power of 18A and has a low clamping voltage of 18.7V.

The TPSMD18A is a unidirectional device and works on the principle of avalanche breakdown. When voltage across the diode exceeds the breakdown voltage of 19V, the current exceeds a certain threshold and the diode enters the avalanche region. Here, a large amount of electrons and holes will be generated in the junction as a result of the avalanche diode action and the energy gap, creating a large number of charge carriers and thus rapidly reducing the voltage across the diode. This reduces the peak voltage and current of the transient overvoltage and protects the sensitive electronic components from damage.

The TPSMD18A diode offers excellent clamping performance, with high surge capability and a low clamping voltage. It is suitable for use in various applications such as AC adapter power supplies, LCD panel, LED backlight, and other portable and commercial equipment which may be exposed to transient voltage spikes and surges.
