2EZ100D/TR12 Application Field and Working Principle

Diodes are amongst the most important types of active components used to build electrical circuits, and the 2EZ100D/TR12 is a single Zener diode, which can help protect circuits from abnormal and high voltage fluctuations. This article will discuss the application fields, as well as the working principle of the 2EZ100D/TR12.

Application Fields of 2EZ100D/TR12

The 2EZ100D/TR12 is a single Zener diode, which is encapsulated in a 4-pin TO-252 package. It is suitable for applications such as overvoltage protection and general voltage regulation. With the Zener voltage range of 92V, the 2EZ100D/TR12 can be used effectively in telecommunication systems, as well as AC and DC applications.

Benefits of using the 2EZ100D/TR12 include its high stability, low forward voltage drop, and high power dissipation capability. It has a low junction capacitance, which provides low noise operation and high switching speeds. Furthermore, it is RoHS compliant, and has an operating temperature range of -65°C to +125°C, which makes it suitable for a variety of applications.

Working Principle of 2EZ100D/TR12

The 2EZ100D/TR12 is a single Zener diode which operates by allowing a voltage to pass through it in only one direction, from anode to cathode. When the Zener voltage is reached, the diode then clamps the voltage, creating a stable voltage and preventing spikes from reaching the protected circuit. This is turn helps protect the circuit from damage due to overvoltage.

The resistor Rd2 is used for current limiting for the 2EZ100D/TR12. With the correct resistor value, the maximum power dissipation is ensured. Furthermore, the selection of the resistor Rd2 is important as it determines the breakdown voltage and the maximum Zener current.

In order to achieve an optimal protection, the 2EZ100D/TR12 should be connected to a circuit equipped with a fast-recovery device such as polyswitch or MOV (Metal Oxide Varistors). This combination will help protect the circuit from failure due to transient overvoltage spikes.

In conclusion, the 2EZ100D/TR12 is a single Zener diode which is encapsulated in a 4-pin TO-252 package and is suitable for telecommunication systems and AC/DC applications. With the high stability, low forward voltage drop, and low noise operation, it is a great choice for overvoltage protection and general voltage regulation. Moreover, it should be used in combination with a fast-recovery device for optimal protection.
