Diodes are semiconductor devices that are capable of carrying out current in one direction only. They are most often used for rectification of AC current to DC. A rectifier diode array is an integrated electronic component that incorporates two or more diodes within a single package. The BAV99 is a type of diode array that performs both low voltage switching and low capacitance switching in applications that require high reliability.The BAV99 is a dual, surface mount, switch and rectifier diode array that consists of two independent NPN switch transistors, two Schottky diodes and two 1.2V Zener diodes, all contained in a small package. It has a low capacitance design, allowing it to be used in digital switching, bandpass filters and video amplifiers. The diodes are fabricated using high-performance silicon-germanium epiwafers to ensure high-reliability and low-loss operation.

One of the main applications for the BAV99 is as a switch for low voltage and high-speed switching applications. It can be used for high-frequency filtering, voltage reference operation and AC/DC switching. By connecting the BAV99 to the input of a transistor, it can be used to switch between two distinct analog or digital input signals. The BAV99 can also be used to connect two different voltage sources, such as a battery and a high voltage power supply. The type and strength of the signal that is being switched is determined by the voltage rating of the diode.

The BAV99 is also used for low frequency rectification applications. Rectification in low frequency circuits is used for step-up and step-down of the current. This includes the conversion of AC to DC power and the smoothing of the DC output. The Schottky diodes in the BAV99 have a low forward voltage drop, which allows for efficient power conversion and fast switching. The 1.2V Zener diodes protect the circuit from overvoltage damage due to accidental voltage spikes.

The working principle of the BAV99 is based on the fact that diodes are only able to carry current in one direction. When a current is applied, it can only flow through the diode in the direction of the arrows on the schematic. In switching applications, the NPN transistors act as a bridge between the two diodes. This allows current to flow in both directions. When used for rectification, the Schottky and Zener diodes can convert AC to DC, allowing it to be used for a variety of power applications.

The BAV99 dual diode array is a highly reliable, low capacitance device that is capable of switching and rectifying AC/DC signals in applications that require high speed, low voltage operation. It is suitable for high frequency filtering, voltage reference operation and AC/DC switching, as well as for low frequency rectification applications. Its low capacitance design makes it ideal for use in digital switching, bandpass filters and video amplifiers.
