Diodes are one of the most important components in electrical and electronic systems, and the Zener type single diodes are one of the most common types. Among them, the BZD27C15P-E3-08 is one of the very popular models. To provide acloser look at both the application field and working principle of this type of diode, this article will illustrate both of them in details.

Application Field

The BZD27C15P-E3-08 is mainly used in the power supply, such as switching power supply, and other different kinds of devices with low-power applications. On the other hand, it is also widely used in automatic voltage regulator, voltage detection and various kinds of protection circuits. The application range tend to be quite wide due to the fact that it provides a strong reverse voltage protection which is able to withstand a certain degree of impact current. In addition, the voltage range could be up to 37V with a wide temperature field.

Working Principle

The working principle of this type of diode is similar as other diodes. This type of diode is PN junction type and the current-voltage characteristic is opposite with that of a normal forward-biased diode, meaning that the current in the forward direction is reversed biased. When the voltage of the reverse direction is higher than the avalanche voltage, there will be a sudden avalanche current, by which the current across the diode suddenly increase. This is the theoretical explanation of how this type of diode work.

In addition, the BZD27C15P-E3-08 could also stand to a certain degree of power. It is important to note that the working current of this type of diode should never be over 175 mA. If being over-current, it will immediately decrease the protection ability of the diode.

Conclusion

The BZD27C15P-E3-08, belonging to the Zener type single diode, has a very wide application field. Its working principle is similar to most of the other diodes, but it is also able to endure much higher voltage, and withstand a certain degree of power and impact current. By studying the application field and working principle, we can get a better understanding of this type of diode and its working condition.
