BZX84J-C3V9,115

The BZX84J-C3V9,115 is a silicon planar power Zener Diode with reliable reversing avalanche characteristics and a five-terminal Zener voltage reference source. It belongs to the Single Zener diode family of diodes, which are mainly used in voltage regulation, as a circuit element to control the voltage in a range of applications. It is widely used in low power applications and provides a good low power alternative for other power applications.

Coming to the application field of the BZX84J-C3V9,115, it is mainly used in voltage regulation, current regulation and protection against surges. It can be used to reduce the ripple from a power supply, act as a reference for circuits and to prevent overvoltage damages in a circuit. Moreover, it can be used for the DC-DC conversion without the need of an inductor-capacitor combination. It is also used in audio amplifiers to reduce switching noise and provide a low noise operating environment.

The working principle of the BZX84J-C3V9,115 can be explained as follows: when a direct current is passed through it, the diode turns ‘on’ and becomes a closed switch. Once the voltage across it reaches the Zener voltage or the breakdown voltage, then it results in the ‘Zener breakdown’. The Zener breakdown, in turn, results in the conduction of electron current and thus, the voltage falls below the breakdown voltage. By controlling the current passing through it, the Zener diode controls the voltage of that circuit, without leading to any loss in power.

To conclude, the BZX84J-C3V9,115 is a Single Zener diode that is used for voltage regulation, current regulation and protection against surges. It works by regulating the current passing through it, without the occurrence of any loss in power. With its five-Terminal Zener Voltage reference source, it proves to be an efficient and economical solution for a number of power regulation applications.
