The 2EZ20D10/TR12 also has an operating temperature range of -40°C to +125°C and is available in the smaller SOT-23 package.

Applications and Working Principle

The 2EZ20D10/TR12 is designed for use in various industrial, commercial and consumer applications. The use of low-leakage, glass passivated junctions ensures high reliability and long system operation, while the low forward voltage provides cost and space savings compared to other Zener diode products.

The 2EZ20D10/TR12 is also well suited for voltage protection where a constant voltage is required. When the voltage across the diode is greater than the forward voltage and the current is within its power rating, the voltage is stabilized and maintained until the current limits. In addition, the diode can act as a voltage regulator for controlling and protecting against fluctuations in the input power.

The working principle of the 2EZ20D10/TR12 is based on the Zener breakdown mechanism. When the diode is reverse biased, the electric field strength in the junction region increases and reaches a value at which the electrons and holes crossing the depletion region gain sufficient energy to create the current which will cause the Zener breakdown. This breakdown voltage can be between 6V and 12V depending on the model of the diode and will remain constant until the current exceeds the maximum value.

The 2EZ20D10/TR12 is a Zener diode with a 12V Zener voltage, which means that it helps maintain a steady voltage for circuits by keeping the voltage constant, regardless of sudden changes. To do this, it uses a Zener breakdown mechanism to allow current to flow from the reverse bias to the anode and then to the cathode. This constant voltage helps prevent voltage surges and drops, allowing for more stable and reliable performance of electronic components.

Conclusion

In conclusion, the 2EZ20D10/TR12 is a 12V Zener diode designed for use in various industrial, commercial and consumer applications. Its use of a low-leakage glass passivated junction ensures long system operation and the low forward voltage provides cost and space savings compared to other Zener products. The Zener breakdown mechanism of the 2EZ20D10/TR12 helps stabilize the voltage and protect against voltage surges, allowing for more reliable and stable performance of electronic components.
