Diodes are two terminal electronic semiconductor devices that typically allow current to flow in only one direction. Zener diodes are diodes designed to operate in reverse breakdown mode and are used to provide a very precise voltage reference for voltage regulation circuits and for other specialized applications. The CZRA4749-G is a single Zener diode that offers a breakdown voltage of 4.7 V, with a maximum power rating of 125 mW, making it suitable for a variety of applications.

The reverse breakdown voltage of the CZRA4749-G is 4.7 V, which makes it perfect for applications where a fixed voltage reference is required. It can also be used in switching applications, as it has a low reverse leakage current of 1 mA and a low maximum forward voltage drop of 1.1 V.

The CZRA4749-G is particularly popular in small, low-power voltage regulation applications, such as battery operated devices, handheld equipment and MP3 players. It can also be used in automotive systems, where it ensures the power supply remains stable even when the input voltage fluctuates due to changes in the engine speed, as well as in industrial applications such as temperature control.

The CZRA4749-G is designed to operate reliably in temperatures ranging from -55 to +150 degrees Celsius. Its high peak power rating of 125 mW and its maximum reverse current of 1 mA make it ideal for applications requiring a stable voltage reference in a variety of temperatures and conditions.

In addition, the CZRA4749-G is designed to be compatible with high-frequency circuits, such as motor control circuits, due to its low capacitance and high forward current rating. The CZRA4749-G is also constructed with a lead frame construction, which allows for effective heat dissipation and excellent thermal management.

The principle of operation of the CZRA4749-G is relatively simple. When it is subjected to a reverse voltage greater than its breakdown voltage of 4.7 V, the diode conducts in both directions and the total current flowing through it is limited to the value determined by the resistor in series. The voltage across the diode remains approximately constant over a wide range of current, allowing for a stable voltage reference in even the most demanding applications.

In sum, the CZRA4749-G is a single Zener diode designed for a wide range of applications requiring a reliable, stable voltage reference. It has a breakdown voltage of 4.7 V, a peak power rating of 125 mW and a reverse leakage current of 1 mA, making it suitable for use in various small, low-power voltage regulation applications such as battery operated devices, handheld equipment and motor control circuits. It is constructed with a lead frame construction for effective heat dissipation and thermal management. The CZRA4749-G works on the principle of providing a stable voltage reference in the presence of a reverse voltage greater than 4.7 V across its terminals.
