The 3EZ68D10/TR12 Zener Diode is a single diode which is specifically designed to limit the current flowing through it. This diode is most commonly used to allow a current to flow with moderate voltage control in regulating applications.

Application Field:

The 3EZ68D10/TR12 can be found in a variety of applications. Commonly, it is used in voltage regulation circuits, voltage regulation modules, and low-noise linear circuits. This diode is suitable for applications in computers, communication devices, audio equipment and power indication devices.

Working Principle:

The 3EZ68D10/TR12 works based on its forward-bias using the diode\'s inherent junction. This forward biasing results in a low- impedance pathway, which allows the current to flow. However, when reaching a certain voltage threshold, the diode begins to enter its reverse-bias state. This allows the diode to control the current that is allowed to flow through it.

When the voltage drops to the diode\'s given Zener voltage, the diode begins to enter the reverse bias, this causes the current to be limited by the diode. The diode continues to remain in this state until the applied voltage is greater than the Zener voltage for a prolonged period of time. This prevents the voltage from exceeding the Zener voltage level.

In summary, the 3EZ68D10/TR12 works as a voltage regulating device, by limiting the current passing through it when a predetermined level is met. Once this level is met, the diode begins to allow partial current through, creating a regulating effect.

Advantages:

The 3EZ68D10/TR12 comes with many advantages. Firstly, this diode offers high power efficiency due to its low voltage drop when it is in its forward bias. Secondly, the diode is extremely reliable and assured to be within its given parameters and perform as intended. Most importantly, its low reverse voltage, low reverse current, and short recovery time ensures maximum performance for its intended application.

Limitations:

The 3EZ68D10/TR12 has a few limitations. Firstly, its maximum operating temperature is limited to a range from –55°C to +150°C. Secondly, this diode might not be the best choice for applications that require the diode to operate for long periods of time, or those requiring an extremely high amount of voltage. Finally, the device is sensitive to moisture, and should not be allowed to reach its maximum humidity rating, which is 95%.

Conclusion:

The 3EZ68D10/TR12 is a single diode specifically designed for current limiting applications. This diode operates based on its forward-bias and Zener voltage characteristics. It is largely used in voltage regulation circuits, voltage regulation modules, and low-noise linear circuits. This diode provides a high-power efficiency, reliable performance, and a maximum operating temperature of –55°C to +150°C. It also has its limits, such as long operating applications and moisture sensitivity.
