CZRA4734-G

A Zener diode is a particular type of diode that, unlike a normal one, allows current to flow not only from its anode to its cathode, but also in the reverse direction, when the Zener voltage is reached. The CZRA4734-G is a single Zener diode with a breakdown voltage range of 4.7 to 7.3 volts.

The most common application for Zener diodes is to regulate the voltage across a load. By connecting a Zener diode in reverse biased configuration with a resistor in series, the current flow through the diode will be limited by the resistor. When the voltage across the load reaches the Zener breakdown voltage, the current though the diode will increase, making the voltage across the load remain constant at the Zener voltage.

The CZRA4734-G can also be used in voltage clamping applications, where it is used to limit the voltage of a circuit or signal to a certain level. This can be useful for protecting sensitive components, or to prevent oscillations in a signal. The Zener diode can also be used as a reference voltage source, by connecting a current limiting resistor in series with the diode. The voltage at the anode of the diode will remain at the Zener voltage.

The CZRA4734-G has a power dissipation rating of 350mW, which means that it can be used with up to 350mW of power. It has a maximum reverse current of 500uA at the Zener voltage, and a maximum reverse current of 1.0mA at a lower voltage. The Zener diode has a junction Capacitance of 17pF.

In conclusion, the CZRA4734-G is a useful single Zener diode that can be used for voltage regulation, voltage clamping, and as a reference voltage source. It has a wide range of applications, due to its low reverse current, high power dissipation rating, and low junction capacitance.
