3EZ56DE3/TR12

Diodes - Zener - Single

The 3EZ56DE3/TR12 Zener diode is a single-terminal semiconductor device that is commonly used for voltage regulation, voltage referencing and overvoltage protection. The device is constructed from a N-type semiconductor material and is composed of two regions, the one in contact with the anode is called the N-region and the one in contact with the cathode is the P-region.

3EZ56DE3/TR12 Zener diodes are designed to operate in the reverse-breakdown region, wherein the junction between the N-region and P-region becomes so thin due to the high electric fields generated within it that impact ions relatively quickly break down the surrounding material and create a large current path allowing a large damping of the electric fields; this phenomenon called zener breakdown.

The 3EZ56DE3/TR12 Zener diode is designed to allow a defined and constant voltage to drop across it even if the voltage across the diode is varied. This device is used for maintaining a constant voltage across it by dissipating an increased current when the input voltage is increased above the voltage rating.

The 3EZ56DE3/TR12 Zener diode also acts as a protection device, allowing a higher current to flow when a transient overvoltage is applied. If the voltage is too high and the diode works in the zener region, the voltage is reduced to the zener voltage level; thus, protecting it from damage.

The 3EZ56DE3/TR12 Zener diode can also be used for precision combined regulation, bias utilization, and current limit flows. Its main characteristic is that it can maintain a reasonably constant voltage across it regardless of the current flowing through it.

In terms of application fields, the 3EZ56DE3/TR12 Zener diode has seen usage in a number of electronic devices such as computers, circuit breakers, security systems, power supplies, and audio equipment (amplifiers, preamps, etc.). It can also be used in a variety of power conditioning applications where it can act as a voltage regulator by dissipating a large amount of current when the voltage across it exceeds a certain level.

In conclusion, the 3EZ56DE3/TR12 Zener diode is a versatile semiconductor tool designed to maintain a constant voltage across it, possess overvoltage protection capabilities, and enable precision regulation when used in combination with other components. It applications range from being used in computers and security systems to powering audio amplifiers and preamps and it\'s relatively low cost and easy availability make it an invaluable tool for those seeking a reliable and efficient way to regulate the voltage applied to the electronic components.
