Working Principle of 3EZ39D5E3/TR12

When a high positive or negative voltage is applied to the diode, it enters into breakdown region and starts to pass current. In this mode of operation it is referred to as Zener breakdown.The reverse current flows through the diode even if the applied voltage is reduced below the breakdown voltage due to its reverse bend characteristics. This current is known as the Zener current and is independent of the applied voltage.

When a load is connected across the 3EZ39D5E3/TR12 diode, the load current and the Zener current combine and cause a voltage drop across the diode. This is known as the Zener voltage, and it is the primary difference between Zener diode and the normal diode. Depending on the application, the Zener voltage can be increased or decreased by controlling the current passing through the diode.
