2EZ91DE3/TR8 Application Field and Working Principle

2EZ91DE3/TR8 diodes belong to the family of single Zener diodes. Such diodes are available in three different packages: DO-201AD glass, DO-41 molded plastic and SOD-123 flat lead (FL) surface mount. All three packages are ideal for low power surface mount applications which demand enhanced power dissipation and improved thermal conductivity.

2EZ91DE3/TR8 diodes have a wide range of applications. It can be used as voltage regulator, back-to-back connection for both protection and regulation, and protection against failures caused by low level of applied voltage. This diode is also suitable for use in circuits where transient overvoltage protection is required. Besides above applications, it is also used in automotive applications, handheld consumer products, power supplies, voltage references and transducers.

Working Principle

Zener diode is a polarized electrical device that is operated in reverse breakdown zone of its voltage-current characteristics. It consists of two terminals- anode (A) and cathode (K). When a current passes through the anode and increases beyond the reverse breakdown voltage, the voltage across the two terminals remains constant. This phenomenon is known as the Zener Breakdown. The voltage-current characteristics of 2EZ91DE3/TR8 diode are highly stable with temperature and time. The reverse breakdown voltage of this diode is 91 V.

The 2EZ91DE3/TR8 offers many advantages such as low noise, high surge capability, low leakage current, low forward voltage drop, reliable performance and easy testing. It has higher power dissipation capability than conventional diodes. Due to its low cost, it can be used for mass adoption. Furthermore, it offers excellent temperature stability and ESD protection.

Conclusion

The 2EZ91DE3/TR8 diode is a single Zener diode which is suitable for surface mount applications that require enhanced power dissipation and improved thermal conductivity. It is used as voltage regulator, overvoltage protection, and as back-to-back connection for both protection and regulation. This diode offers various advantages such as low noise, high surge capability, low leakage current, and reliable performance.
