Diodes - Zener - Single

Introduction:

The BZT52C7V5-HE3-08 is a single Zener diode manufactured by STMicroelectronics. It has a reverse voltage rating of 7.5V and a power dissipation limit of 500mW. This series of Zener diodes offers good performance with superior quality and reliability, making them suitable for various applications.

Application Field:

The BZT52C7V5-HE3-08 is mainly used in power supply and circuit board applications. It is often used to regulate and protect circuits from excessive current and electrical noise caused by sudden changes in voltage. The Zener series can also be used to provide protection against overvoltage, such as when equipment needs to be isolated from noisy power sources. Other applications include motor control, automotive applications, circuit and load protection, and noise filtering.

Working Principle:

Zener diodes rely on a specific reverse-biased voltage in order to function properly. Reverse-biasing occurs when the voltage of the diode is higher than the voltage on the other side. The Zener diode has a reverse breakdown voltage, which is the voltage at which current will be conducted from one side to the other. As the voltage increases further, current will increase at a set rate. The reverse voltage of a Zener diode is fixed and can be regulated, making them ideal for regulating the voltage of a circuit by transmitting the current through it in order to change the voltage level.

When the reverse voltage is applied to the diode, the depletion region between the p- and n-type materials begins to increase. This allows electrons to flow from one side to the other, and current to flow through the diode. The current is released by the electrons that have been freed from the depletion region, and as the voltage is increased, more electrons are freed and more current is conducted. This is known as the Zener effect, and it makes Zener diodes suitable for regulating the voltage of a circuit.

Conclusion:

The BZT52C7V5-HE3-08 is a high-quality single Zener diode manufactured by STMicroelectronics. This series of diodes is mainly used in power supply and circuit board applications, where it is often used to regulate and protect circuits from excessive current and electrical noise caused by sudden changes in voltage. The Zener diode relies on a specific reverse-biased voltage and has a reverse breakdown voltage, which is the voltage at which current will start to flow through it. This is known as the Zener effect, and it makes Zener diodes suitable for regulating the voltage of a circuit.
