Diodes - Zener - Arrays

The VMZT6.8NT2L is an integrated diode array that consists of two zener diodes connected in series. It is used for voltage regulation, static protection and line drop compensation. This device is commonly used in signal level shifters, power supplies and protection circuits.

The Zener diodes connected in series create a single voltage rating, which is the sum of the two Zener voltages. The output voltage is largely independent of the input current, meaning that the output will remain relatively constant even as the input current fluctuates.

The VMZT6.8NT2L has a maximum power rating of 450mW and a maximum reverse current of 250uA. For applications that require the Zener diodes to operate at higher temperature ranges, the device is designed with a static thermal impedance of 8.5°C/W.

The VMZT6.8NT2L Zener diode array is typically used in power supplies, signal level shifters and protection circuits. In power supplies, the device can be used to regulate output voltage and reduce the loss of energy due to line drops. In signal level shifters, the device can be used to adjust the voltage levels in order to interface different types of components. In protection circuits, the device can be used to protect sensitive components from high voltage spikes or excessive input current.

The working principle behind the VMZT6.8NT2L is that of a typical Zener diode. A Zener diode is a diode designed to allow current to flow in the forward direction just like a standard diode. The difference is that when the voltage across the diode reaches a certain threshold, known as the breakdown voltage, current begins to flow in the reverse direction. This reverse flow of current is called Zener breakdown.

The VMZT6.8NT2L is designed to have two diodes connected in series, each with a different breakdown voltage. When the input voltage is below the total breakdown voltage of the two diodes, the diodes do not conduct electricity in either direction. However, when the input voltage reaches the breakdown voltage, current begins to flow in the reverse direction, providing a constant output voltage that is independent of the input current.

In conclusion, the VMZT6.8NT2L Zener diode array is a useful device for managing power and protecting sensitive components. The device has a wide range of application fields and its working principle is that of a standard Zener diode. It is designed with two diodes connected in series that allow current to flow in the reverse direction when the input voltage reaches a threshold, providing a constant output voltage.
