2EZ47D/TR8

2EZ47D/TR8 Application Field and Working Principle

The 2EZ47D/TR8 is a 1-watt Zener silicon diode that provides advanced Zener voltage regulation. With a guaranteed minimum Zener breakdown voltage of 5.1V at 75mA, and a maximum reverse power dissipation of 1 W, the 2EZ47D/TR8 is suitable for a variety of applications such as voltage regulators, voltage limiter, reverse Zener protection, linear voltage regulator, and on-chip voltage regulation.

The 2EZ47D/TR8 operates in the reverse-biased mode, in which it allows current to flow in one direction only. This limits the forward current and maintains a constant voltage across the diode, which is known as the Zener voltage. The Zener voltage is determined by the doping level of the intrinsic semiconductor used within the construction of the 2EZ47D/TR8.

The Zener breakdown property is essential for a variety of applications such as voltage regulator, voltage limiter and reverse Zener protection. In the voltage regulator application, it ensures the output voltage remains constant even when the input voltage is varied. In addition, the reverse Zener breakdown property is used in reverse Zener protection to clamp overvoltage spikes in the circuit to prevent damage due to excessive current.

In conclusion, the 2EZ47D/TR8 has a vast array of applications, due to its Zener breakdown property and its ability to withstand high power dissipation. It is suitable for use in a variety of circuits, such as voltage regulators, voltage limiters and reverse Zener protection circuits.
