Diodes: Zener - Single

BZV55C62 is a type of single Zener diode, which is widely used in various applications where a special reverse bias semiconductor device is required. It is a general purpose diode with a nominal reverse breakdown voltage of 6.2V.

Application Field

BZV55C62 is commonly used in various electronic circuits and assemblies, such as power supply regulation, voltage regulation, voltage limiting and overvoltage protection. Due to its low voltage drop in forward current conduction, it is especially suitable for low voltage applications and in situations where power dissipation is a concern.

It is preferred for applications where voltage and current have critical requirements or are required to be varied in inverters and voltage regulators. Additionally, it is efficient, cost effective and reliable option for low noise and power conversion applications. It is also frequently used for reverse bias protection for semiconductor devices, including transistors and rectifiers.

BZV55C62 is an ideal solution for the miniaturization of devices, mainly because of its small size, which allows it to be used in applications where space is a limiting factor. It can also be used in automotive and military grade applications, due to its high reliability in various harsh and extreme environments as well as its resistance to shock, vibration and temperature changes.

Working Principle

The working principle of a BZV55C62 depends on the "Dynamic Impedance" property of a diode, which is the ratio of the voltage and current in a diode. When the diode is forward biased, current passes through and voltage across the junction is low. On the other hand, when the diode is reversed biased, a large voltage appears across the junction and the current is predetermined by the diode\'s dynamic impedance.

BZV55C62 works as a voltage regulator because it has a specific reverse bias voltage level, which can be controlled accurately with a Zener voltage regulator. When reversed-biased, the zener diode starts to conduct at a predetermined voltage level, while clamping the output voltage. The value of current passing through the diode must be monitored, as it is limited by the power rating of the diode. This enables the output voltage to remain more or less constant over a range of input voltages.

The BZV55C62 can also be used as a reverse voltage protection device, because it efficiently limits the voltage that is being fed to the other elements in the circuit. This is made possible by the breakdown voltage of the diode, which ensures that no more than a predetermined amount of reverse voltage is allowed through the system. This protects other elements from the otherwise damaging high voltage.

Similarly, the zener diode can also be used in overvoltage protection circuitry where the excess voltage needs to be shunted away from the circuit. Here, the diode behaves as a voltage switch, which shorts the voltage when the predetermined voltage level is reached. This prevents the other circuit components from receiving higher than expected voltages.

Overall, the BZV55C62 is a reliable and versatile diode, suitable for a variety of applications such as power supply regulation, voltage regulation, voltage limiting and reverse protection. With its distinct properties and ability to limit current and voltage, it is an ideal choice for almost any application.
