TVS – diodes are a type of semiconductor which acts as a protection device for protecting against dangerous electrical and ESD (electrostatic discharge) infrastructures. The SA120A-E3/73 is an unidirectional diode specifically made for protection from such discharges. This diode is formed by multiple junction diodes which can be connected in either a linear or non-linear arrangement form.

The major application field of SA120A-E3/73 is to protect low power utility circuits such as telecom, audio, computer and other sensitive electrical and ESD infrastructures from transient voltage spikes. This diode can also be used to protect People from sudden surge of electricity. Its applications also include protecting interface pins, surge impedance loading, data buses, protection from ESD (electrostatic discharge), and so on.

SA120A-E3/73 is basically a type of Zener diode, which works on a simple principle. When there is an electrical surge, this diode allows the required amount of current to pass through it. When the spike is over, the excess current is safely provided to ground. This diode is designed to be connected in series with the circuit that needs protection, so that the excess current passes through it and is diverted to ground. This reduces the voltage passing through the circuit, thus protecting it.

SA120A-E3/73 operates in voltage operating range of 3V to 175V. It has fast response time of 5 ns and peak pulse current rating of > 20000A. It also has excellent power rating and high insulation resistance. It can also withstand high temperature up to 175° C and provides tight clamps which protect sharp surges too.

The overall performance of the SA120A-E3/73 TVS diode is remarkable, and it is suitable for applications in telecom, audio computer and other sensitive electricalcircuits. Moreover, it provides protection from ESD, interface pins, and quick spikes. It is an ideal choice for those who need protection from transient voltage surges.
