A 2EZ39DE3/TR12 is a type of Single Zener Diode. A Zener Diode is a special type of diode that is designed to regulate voltage. It functions by allowing the flow of current in a single direction, and additionally, when the voltage reaches a certain level, it will allow reverse current flow. This reverse current flow is designed to regulate the voltage, preventing it from exceeding the predetermined level.

The Single Zener Diode, 2EZ39DE3/TR12, is typically used in circuits as either a voltage regulator, voltage reference, or overvoltage protector. It primarily serves as a clamping device, allowing it to pass through the excessive voltages, while still regulating the voltage output to remain within predetermined levels. This allows the device to be used in a number of applications including power supplies, switching circuits, audio and radio equipment, data processing machines, and more.

The 2EZ39DE3/TR12 has a Zener voltage (or breakdown voltage) of 12 Volts. This is used to determine the level of voltage that it will regulate. Additionally, it has a power dissipation ranging from 2-watts to 6-watts, depending on the rate of heat dissipation. Its peak repetitive state reverse voltage is also 12 Volts, and its forward current of 20 mA.

The 2EZ39DE3/TR12 Single Zener Diode is constructed from an N-type semiconductor material, and uses Zener breakdown principle to regulate the outgoing voltage. This basic design has remained unchanged since its introduction, and is now widely used in both commercial and military applications. The reason for its success is due to its low cost of manufacture and reliable operation.

The 2EZ39DE3/TR12 has a relatively simple working principle. As current flows through the device, the PN junction creates a potential difference across the two regions of the diode (Anode and Cathode). This potential difference, also known as the threshold voltage, allows current to flow from Cathode to Anode in a forward direction. When the voltage reaches a predetermined level, the Zener voltage, the PN junction is reversed and current begins to flow in the opposite direction. This prevents the voltage from exceeding the Zener voltage and regulates the output to that predetermined level.

In summary, the 2EZ39DE3/TR12 is a Single Zener Diode designed to regulate voltage. It is widely used in a variety of applications, most notably as a voltage regulator, voltage reference, or over-voltage protector. It is constructed from an N-type semiconductor material with a Zener voltage of 12 Volts, and uses the Zener breakdown principle to regulate the output. Additionally, it has a power dissipation ranging from 2-watts to 6-watts, and a peak repetitive state reverse voltage of 12 Volts.
