The AZ23C3V3-E3-18 diode- Zener Array is a type of diode array which offers robust power without compromising its performance. It is mainly used in applications such as input surge protection and voltage clamping for DC/DC converters and other circuits. It offers low on-resistance and high temperature operation.

The AZ23C3V3-E3-18 diode- Zener Array consists of three separate elements, namely a Zener diode, a control FET, and a resistor. The Zener diode is used to stabilize the gate voltage of the FET, while the control FET is used for current limiting. The resistor is used for temperature compensation, and it also helps to limit the voltage increases.

The primary function of a Zener diode is to allow current to flow in one direction and provide voltage regulation. The Zener diode consists of a semiconductor p-n junction. When the voltage exceeds the breakdown voltage of the junction, a small current begins to flow, allowing the voltage to be maintained at a preset level. The AZ23C3V3-E3-18 diode- Zener Array incorporates the same principle, but adds a control FET for protection against overvoltage.

When the voltage at the output of a DC/DC converter exceeds the Zener diode\'s breakdown voltage, the control FET turns on and shunts the excess current away from the power source. This helps to prevent damage to the converter or other components. The resistor is used to adjust the current limit set by the FET, allowing the circuit to regulate voltage levels while providing surge protection.

The AZ23C3V3-E3-18 diode- Zener Array is ideal for low voltage applications, such as input surge protection and voltage clamping for DC/DC converters. It is a reliable and cost-effective solution for protection against overvoltage. The combination of Zener diode and control FET ensures that the circuit can respond quickly to changes in voltage, providing reliable protection against voltage spikes.
