Diodes - Zener - Arrays : PZU5.6DB2,115 Application Field and Working Principle

PZU5.6DB2,115 is a Zener diode array consisting of two Avalanche Zener diodes connected in inverse parallel with each other. It is typically used in applications where high-voltage protection is required.

At low voltages, PZU5.6DB2,115 behaves similarly to a conventional zener diode. However, as the voltage exceeds a breakdown voltage (typically around 5.6V), the PZU5.6DB2,115\'s "avalanche" capability comes into play. In this mode, further increases in voltage can be accommodated without the device breaking down. This makes the PZU5.6DB2,115 extremely well suited for high-voltage applications.

The PZU5.6DB2,115\'s typical protection voltage is 5.6V, with a maximum breakdown voltage of 30 volts and a maximum reverse current of 0.5 mA. The device is capable of handling up to 100mA of forward current with a power dissipation of 500mW. The reverse leakage current is typically in the range of 1µA.

The PZU5.6DB2,115 is widely used in applications such as low-power sensors, voltage-regulating circuits, and voltage-sensing circuits. For instance, it can be used in automotive electronics for protection against short circuit and transients, or in consumer electronics for protecting batteries from overvoltage.

The working principle of PZU5.6DB2,115 can be explained as follows: When the voltage across the PZU5.6DB2,115 is below 5.6V, the device behaves like a conventional zener diode, with a reverse breakdown voltage of 5.6V. However, when the voltage exceeds 5.6V, the avalanche breakdown phenomenon is initiated, and the device allows sustained currents to flow even at higher voltages.

In addition to providing protection against overvoltage, the PZU5.6DB2,115 also serves as a voltage-limiting device. When the voltage is reduced, the device regains its full protection voltage and ensures that the voltage does not fall below the specified value. This ensures that the sensitive electronic components are not damaged due to overvoltage or voltage surges.

Lastly, the PZU5.6DB2,115 is also used for temperature compensation. Due to its low thermal coefficient, the device can be applied in circuits requiring precise temperature compensation.

In summary, the PZU5.6DB2,115 is a high-voltage protection component used in various applications such as low-power sensors, voltage-regulating circuits, and temperature compensation. It is capable of providing reliable protection to the circuit components even when the voltage exceeds its breakdown voltage.
