Application Field

The 2EZ140D10E3/TR12 is quite versatile and can be used in a variety of power supply regulation and decoupling applications. It finds most of its uses in standard voltage regulation, voltage clamping and spike suppression, as well as series regulation. It is commonly used as a power supply decoupling component in on-board transistors.

The component can also be used for transient voltage suppression, such as during power-up or power-down of the device. It is ideal for use in high speed, sensitive applications such as in microprocessors, phones, and portable devices. It is especially well suited for applications requiring high reliability, such as in automotive and industrial parts.

Working Principle

The 2EZ140D10E3/TR12 works according to the principle of Zener breakdown. When the reverse voltage across the diode reaches the Zener voltage, the diode starts to conduct. The Zener voltage (or Vz) can be set by adjusting the doping concentration or doping ratio. The Zener voltage of the 2EZ140D10E3/TR12 is fixed at 10V.

The component is designed to provide real-time regulation once the forward or reverse voltage reaches the specified limit. This helps reduce power consumption and helps prevent damage to sensitive on-board transistors by rapidly responding to voltage changes. In addition, the component has very low capacitance, which helps reduce power consumption.

Conclusion

The 2EZ140D10E3/TR12 is a single Zener diode designed for voltage regulation and decoupling applications. It can withstand up to 10V of reverse voltage and has a power rating of 500mW. It features low junction capacitance, making it particularly suitable for high speed delicate applications. This component can be used to provide real-time voltage regulation, voltage clamping and transient voltage suppression.
