TVS (transient voltage suppressor) diodes have become an essential part of electronic circuits in order to inhibit high voltage transient pulses from damaging sensitive components. SA28-E3/73 is one of the most widely used TVS diodes due to its cost-effectiveness, reliable performance and large number of applications. This article will discuss the application field and working principle of SA28-E3/73.

First of all, the application field of SA28-E3/73 is wide. It is most commonly used to protect sensitive components from over-voltage transients. It can also be used to protect signal circuits from electrostatic discharge (ESD), to suppress surge voltage and transient currents, and to protect against inductive voltage spikes and transient pulses. Another common application for the SA28-E3/73 is to provide short circuit protection by limiting the current in the event of an overload. It can also be used for current limiting and fuse replacement applications.

The SA28-E3/73 is a unidirectional device and therefore only works in one direction. This means that it can only protect against high voltage transients in one direction. The maximum working voltage of the SA28-E3/73 is 28V, and its maximum breakdown voltage is between 28V and 35V. The maximum working current is 3A, and its maximum breakdown current is between 3A and 4A. It has a clamping voltage of 73V and a capacitance of 18pF.

The working principle of the SA28-E3/73 is as follows. When the applied voltage is below the breakdown voltage, the diode is in its "off" state and the current will not flow through it. When the voltage rises above the breakdown voltage, the diode is in its "on" state and current flows freely through it. As the current passes through the diode, the voltage is reduced and the excess voltage is dissipated as heat. This prevents the voltage from rising too high and damaging sensitive components. The SA28-E3/73 is specifically designed to be able to absorb large surges of current without being damaged.

The SA28-E3/73 is a very reliable and cost-effective device suitable for a range of applications. Its working principle and application field are both straightforward and easy to understand. The device can effectively protect against over-voltage transients and has a wide range of uses, making it a very useful component in any electronic circuit.
