3EZ170DE3/TR8

The 3EZ170DE3/TR8 diode is a single Zener diode structure designed to provide a stable regulated output voltage. It is commonly used in the protection and control of current and voltage levels in power supplies. This diode features low forward voltage drop and a low reverse leakage current.

The 3EZ170DE3/TR8 has a wide array of potential application fields. It is commonly utilized in automotive, industrial, and audio applications. The diode is primarily used as a voltage regulator to stabilize output or provide protection from overvoltage. It can also be employed in AC and DC motor control, and cell phone power management. The diode is also capable of providing clipper protection in certain audio applications, enabling sound designers to shape the waveforms of sounds.

The principle of operation behind the 3EZ170DE3/TR8 is based on the Zener effect. The Zener effect occurs in heavily doped PN junction semiconductor devices, like the diode, when the reverse voltage applied to the diode exceeds the breakdown voltage of the diode. This results in electrons moving throughout the device and across the junction, creating a “breakdown” of the junction and resulting in a proportionally increased current flow.

When in operation, the 3EZ170DE3/TR8 maintains a constant output voltage within a specific range of input voltages. This is known as the voltage regulation band. When the input voltage fluctuates within the range of the voltage regulation band, the output maintained by the diode remains constant. This phenomenon is known as Zener regulation.

The 3EZ170DE3/TR8 diode has a reverse voltage breakdown of 8.0V, a rated maximum power of 150mW, and a low forward voltage drop of 0.62V. The diode is offered in a SOD-323 package, which provides a small size that makes it well-suited for a variety of applications that require a regulated output over a wide range of input voltages.
