BZX84C10S-7

The BZX84C10S-7 is an array diode with 7 diodes which are the same polarity and voltage.
Each diode functions as a typical zener diode with a 3.9V breakdown voltage and a 5mA current across it.
The BZX84C10S-7 array is often used in voltage regulator circuits for applications such as low-voltage power supplies, as it can efficiently supply multiple voltages without having to use multiple discrete diodes.

The principle of operation in the BZX84C10S-7 is quite simple. The zener diodes are connected in parallel, with the cathodes of each connected together and the anodes connected to their respective terminals.
When a voltage is applied across the terminals of the BZX84C10S-7, the voltage will divide across the 7 diodes in such a way that the voltage across each diode is the same. This is due to the fact that they all have the same breakdown voltage and a low internal resistance which allows the current to be divided evenly between the diodes.

This allows the BZX84C10S-7 to be used in a variety of applications. It is often used as a low-voltage power supply regulator to supply multiple voltages, or as an array of zener diodes for protection circuits for low-voltage components.

The BZX84C10S-7 is also used as a voltage reference source, providing a precise and stable voltage to a circuit. This is very useful in precision measurements and control circuits.

Finally, the BZX84C10S-7 is often used as an AC waveform converter. By connecting the array of diodes in series with a capacitor, it is possible to convert any AC waveform into a precision DC voltage.
