TVS-Diodes are a type of technology and solution used to protect sensitive electronic components from the destructive force of lightning strikes, power surges, and static electricity. They are also used in the telecommunications sector from the long-distance transmission of signals, to digital subscriber loop applications in the home. The technology combines an avalanche diode with a surge suppression device, often a resistor, to provide an effective barrier in protecting systems from transients.

The TPSMC36A is a high-performance Transient Voltage Suppression (TVS) Diode designed for applications where high surge immunity is required and size and cost are a concern. It is available in an ultra-small SOD882 superficial mounting package with caps available as an optional accessory. The TPSMC36A is a unidirectional device with a standoff voltage of 36 volts and it is designed to protect sensitive electronics from over-voltage induced by electrostatic discharge (ESD) and induced surge events. With its low bulk capacitance of 65pF on most units and low leakage current of 200nA, the TPSMC36A provides a complete solution for advanced devices such as flat panel displays, digital still cameras, laptop computers, and other high-frequency electronics.

The working principle of the TPSMC36A involves a breakdown voltage and clamps the voltage across the device when it exceeds this level. Then it can absorb transients, conduct current and surge away the energy. Once the surge dissipates, the device returns to its normal state. This process of absorption and diffusion of energy is known as \'avalanche breakdown\' and is repeated each time it is triggered. This allows it to remain functional until the surge is removed from the system.

Depending on the application, the TPSMC36A is available in different configurations. Some of these are Non-polarized (without pin rating), Bidirectional (with a positive and negative pin rating) and Unidirectional (with a positive only pin rating). In addition, it is also available in an AC type for surge protection between Live and Neutral lines and a DC type for surge protection between Power lines and ground.

Overall, the TPSMC36A provides smart solutions to reduce the risk of electrostatic damage from rare, yet costly electrostatic/electromagnetic surge events. It is an excellent choice for applications where size and cost are critical, such as consumer electronics, industrial equipment, and medical instruments.
