Introduction

Diodes - Zener - Arrays (DZA) are semiconductor devices that allow for the rectification and regulation of current. DZA devices are useful for electronic applications where voltage regulation or rectification may be required. The BZB784-C10,115 is a type of DZA component that is manufactured by Bourns.

Description

The BZB784-C10,115 is a dual-channel Zener diode array that can support a maximum established voltage of 155 volts. The device is composed of two series connected diodes which each have a single maximum continuous reverse voltage of 115 volts. The maximum surge forward current of each individual diode is 2 milliamps, while the maximum operating temperature is 125°C, and the power dissipation per diode is 550mW. The BZB784-C10,115 is manufactured with a glass passivated junction for increased reliability and stability. The device is designed to have a low forward voltage drop, and has an encapsulation that provides excellent protection against the environment. The component also features low thermal resistance which makes it suitable for high temperature applications.

Application

The BZB784-C10,115 can be used in a variety of circuit designs that require voltage regulation or rectification. Some applications include switch mode power supplies, isolated power supplies, and self-powered converters. The component can also be used in supervisory circuits, where it is used to ensure that the voltage level of a power supply or other supply line does not exceed a certain predetermined value.

Working Principle

The working principle of the BZB784-C10,115 is based on the fact that a diode is a semiconductor device that consists of two regions of semiconductor material, usually a p-n junction. When the P-type material is positively charged, it allows electrons to flow from the N-type material to the P-type material. This is known as forward current. However, when the P-type material is negatively charged, the flow of electrons is reversed, or what is known as a reverse current. A certain voltage across the diode is needed to establish the reverse current. This voltage is known as the breakdown or zener voltage.The BZB784-C10,115 is designed to allow the establishment of a reverse current when the voltage reaches the threshold of 115 volts. The device is a dual-channel Zener diode array, which means that it contains two separate diodes, each with their own threshold voltage. This allows for dual-channel voltage regulation with a single component.

Conclusion

In conclusion, the BZB784-C10,115 is a dual-channel Zener diode array designed for voltage regulation and rectification purposes. The device is composed of two series connected diodes with a maximum surge forward current of 2 milliamps and a maximum established voltage of 155 volts. The component is designed for low forward voltage drop and features low thermal resistance for high temperature applications. The BZB784-C10,115 is suitable for use in switch mode power supplies, isolated power supplies, and self-powered converters.
