Working Principle

The BZX84C11_D87Z works by using the rectifying capabilities of a diode combined with the end-to-end voltage regulation characteristics of a Zener diode. This device is constructed from a P-type semiconductor material and a N-type semiconductor material. The P-type material is much wider than the N-type material, allowing for a greater concentration of charge carriers in the P-type material than in the N-type material, which can lead to variations in voltage. By using the principle of rectification, current is able to flow through the diode in only one direction. By combining the rectification capabilities of a diode with the end-to-end voltage regulation of a Zener diode, the BZX84C11_D87Z is able to provide regulation of the output voltage to a specific level regardless of changes in the input voltage.
