TVS, also known as Transient Voltage Suppressor, is a kind of diode that can effectively limit the transient overvoltage by providing a low impedance path to the source of the transient. It is widely used in various kinds of industries for overvoltage protection against lightning, electrostatic discharge, electrical noise, etc. The SA15-E3/73 is a type of TVS diode which has been increasingly used in different application fields.

The SA15-E3/73 is an unidirectional TVS diode which offers higher power dissipation capability compared to other TVS diodes, and is suitable for applications where large surge currents of up to 1000A are needed. It has a low capacitance of 6pF, making it ideal for protecting a wide range of components from transient overvoltage.

The main application field of the SA15-E3/73 is in the protection of sensitive electronic components, such as microprocessors, and other sensitive electronics during power surges or voltage spikes. It works by offering a low impedance path for the transient, thus diverting the excess power away from the components. It can also be used in automotive applications such as engine control systems, and also in communication systems such as base stations.

The working principle of the SA15-E3/73 is similar to other TVS diodes. The main purpose of the diode is to offer a low impedance path to the source of the transient, thus dissipating the excess power away from the protected device. When the voltage across the diode exceeds the breakdown voltage, the SA15-E3/73 will switch on and start conducting, assuming it has the sufficient current rating for the surge. The excess voltage and current will then be diverted away from the protected device by the low impedance path provided by the diode. After the transient has ended, the diode will switch off and will be ready to repeat the process in the case of another surge.

In conclusion, the SA15-E3/73 is an unidirectional TVS diode with high power dissipation capabilities, suitable for applications where large surge currents of up to 1000A are needed. It is used for protecting sensitive components from transient overvoltage and can be found in applications such as automotive and communication systems. It works by providing a low impedance path for the excess power, thus dissipating it away from the protected device.
