2EZ11D10E3/TR12

Diodes - Zener - Single

The 2EZ11D10E3/TR12 is a single Zener diode with an avalanche breakdown voltage rating of 12 volts. It is a type of diode specifically designed for voltage regulating applications. In electronics, a Zener diode is a diode that allows electric current to flow in either direction and sustain a stable voltage across its terminals.

Application Field

The 2EZ11D10E3/TR12 is commonly used in the electronic circuits for the purpose of voltage stabilization, voltage clamping and ripple-filtering applications. The diode is ideal for electric circuits that require steady and reliable voltages even when they are exposed to continuous transients and fluctuations in the voltage source.

Since Zener diodes are voltage-dependent, they are often utilized as a means of triggering or turning on/off other circuit elements such as transistors, relays, lamps and switches. They are an essential component in the design of a wide variety of voltage-regulating devices.

Working Principle

The Zener diode has the same function and operating principle as a regular diode. It allows current to flow through its PN junction in only one direction. When the diode is exposed to a reverse voltage, it will break down and start to conduct in the reverse direction.

At this point, the voltage across the device (Vz) will remain constant, enabling the diode to act as a voltage regulator. This is called the Zener voltage, recorded as Vz in the diode specifications.

The Zener diode is specifically designed in such a way that it can operate in the breakdown region as if it were in the forward direction. This is made possible by its heavily doped PN junction, which results in significantly reduced reverse breakdown voltages when compared to regular diodes.

Once the operating voltage reaches the breakdown voltage, the current flow across the diode increases exponentially with the increase in voltage. On the other hand, the voltage remains constant regardless of any further increases in current. This makes the Zener diode ideal for voltage regulating applications.

The diode is also designed in such a way that it can dissipate sufficient power to maintain constant voltage levels while also handling high current fluctuations. This helps to prevent excessive inrush current, spikes or even overloads on the connected circuit.

Conclusion

The 2EZ11D10E3/TR12 is a single Zener diode specifically designed for voltage regulating applications. The diode offers voltage stabilization, voltage clamping and ripple-filtering capabilities. It is most commonly used in electric circuits that require steady and reliable voltages even when they are exposed to continuous transients and fluctuations in the voltage source.

The Zener diode works by allowing current to flow through its PN junction in only one direction. When exposed to reverse voltage, it has a breakdown voltage that allows the diode to act as a voltage regulator. This voltage remains constant regardless of any further increases in current.
