When a reverse voltage is applied across the diode, current will flow through the junction and the diode will become conducting, allowing current to flow in the reverse direction. In the Zener breakdown mode, electrons are accelerated until they collide with atoms in the junction, releasing energy that is dissipated in the form of heat. When the reverse voltage reaches the breakdown voltage of the diode, the current will increase drastically at a fixed voltage level, creating a clamped voltage. The device can also be used to regulate voltage and ensure that the voltage remains below a certain level, depending on the breakdown voltage of the diode. ConclusionThe GLL4758-E3/97 is a single Zener diode, commonly used in signal protection, electro-optical control, voltage regulation and other applications. The device has an accurate and stable small-signal performance, low power dissipation and a maximum breakdown voltage range of 9-48V, making it suitable for a variety of applications.
