Working Principle

A Zener diode is a bidirectional diode that allows current to flow in either direction; however, when the voltage across the diode exceeds a certain threshold, known as the breakdown voltage, the diode switches from a conventional diode to a low-resistance, voltage-stabilizing diode. This allows current to flow in both directions, but with only a small voltage differential across the diode. When used in a voltage-regulating circuit, the Zener diode ensures that the voltage across the circuit remains within a certain range.

The 3EZ75D10E3/TR8 is configured in a common cathode configuration, meaning that the anode is connected to the cathode and the anode is connected to the load. When the voltage across the diode exceeds the breakdown voltage ( 75V for this diode ), the diode passes current in both directions, with only a small voltage drop across it. This voltage drop is determined by the type of Zener diode and the current flowing through it. For this diode, the voltage drop is typically 4V at 10mA.

The advantage of this type of voltage regulation is that it allows for precise voltage control, which is ideal for sensitive electronic components. Furthermore, the low forward voltage drop of the 3EZ75D10E3/TR8 ensures efficient operation. This makes it ideal for use in voltage-regulated circuits, such as LED lighting systems, where energy efficiency is a priority.
