3EZ39D2E3/TR12

Diodes - Zener - Single

The 3EZ39D2E3/TR12 is a very popular single-stack Zener diode. This type of diode is used to regulate the flow of electrical current by controlling the reverse bias voltage. In a nutshell, it has two characteristics. On one hand, it works as a resistor, limiting the amount of voltage that can flow back into the diode. On the other hand, it works as a diode, allowing current to flow in one direction only.

The 3EZ39D2E3/TR12 comes with a wide range of specifications to meet various application needs. It has a maximum forward reverse bias voltage of 5.6 volts, a maximum forward current of 0.3 amp, and a maximum power dissipation of 500 mW. The diode is also able to operate at a wide range of temperatures, from -65°C to +150°C.

The 3EZ39D2E3/TR12 is used in a variety of applications, including power supply regulation, amplitude modulation, signal conditioning and signal isolation. It can act as a voltage limiter, a voltage reference, or a voltage regulator. In addition, the diode can be used as part of a voltage multiplier circuit, or to create a voltage ladder.

Application Field and Working Principle

The 3EZ39D2E3/TR12 diode is typically used in a reverse bias configuration. In this configuration, current flowing through the diode is limited by the threshold voltage, the voltage between its anode and cathode. When a voltage higher than the Zener voltage is applied, the diode prevents any further current flow. This is known as the Zener effect, and is the basis of the diode\'s functioning.

In a voltage regulation application, the 3EZ39D2E3/TR12 acts as a voltage reference. This is achieved by connecting the diode in a voltage divider configuration. The voltage divider is a series of resistors and the diode, designed so that the voltage across the diode is a different value than the source. This ensures that the output voltage is always correct, regardless of changes in input voltage or load variations.

The 3EZ39D2E3/TR12 is also used for amplitude modulation and signal conditioning applications. In these cases, the diode acts as an amplifier, enabling signals to be more faithfully reproduced when passed through a voltage divider or a current limiter circuit. Finally, the diode can also be used to create a voltage ladder, allowing delicate electronic components to be connected at different levels.

In conclusion, the 3EZ39D2E3/TR12 is a highly versatile, single-stack Zener diode that can be used in a wide variety of applications. With its wide range of specifications and capabilities, the 3EZ39D2E3/TR12 provides an ideal solution for any electronic system.
