AZ23C4V7-HE3-18

AZ23C4V7-HE3-18 is a type of diode array, which is built from numerous Zener diodes connected in series. These diodes are used for a variety of applications, such as providing protection against overvoltages, regulating ripple current, surge suppression, stabilizing voltage, and acting as a voltage reference. This diode array consists of four Zener diode elements connected in series, with each diode having a breakdown voltage of 4.7 V. The total breakdown voltage of the array is thus 18.8 V. The array also has a peak reverse voltage of 23 V and a Zener diode array to output current capability of 4 A. The primary purpose of the array is to provide current regulation, since each diode element is operating independently with the same current. This allows the array to actively maintain a voltage set point, with an output current dependent on the load. When a load is connected to the array, each diode element will absorb part of the load current, resulting in a regulated output current. Each diode element will also drop some voltage, due to the forward voltage drop. The total output voltage of the array is determined by the sum of the forward voltage drops of each diode element. Zener diodes are also used for protection against overvoltages, in order to clamp the voltage to a fixed level. This is commonly used for protecting sensitive components from lightning surges, for example. The array can also be used for regulating ripple currents. For example, in an AC power supply, the diode array can be connected across the input terminals of the AC transformer, in order to absorb any current spikes or reductions. The diode array is also widely used as voltage reference in circuits, since the total breakdown voltage of the array is known to be reasonably constant over time. In summary, the AZ23C4V7-HE3-18 diode array offers numerous benefits, including voltage regulation, protection against overvoltages, surge suppression, stabilizing voltage, and acting as a voltage reference. It is widely used in many different applications, thanks to its reliable performance and robust design.
