The BAV199W-7 is a diode array capable of reverting alternating currents (AC) to direct currents (DC), known as rectifying. This type of diode is often used as a part of power supplies, motor controls and protection circuits, whose purpose is to ensure the proper functioning of electronic devices and machinery. The BAV199W-7 is composed of 7 Schottky barrier diodes, connected in parallel and commonly referred as an array. In this arrangement, the current passes by several diode’s junctions systematically in the same direction, resulting in a stabilized output voltage. This can then be used for powering electronic circuits and components, such as LED drivers, data interface circuits or a variety of portable hardware.This particular diode is especially suited for high-frequency applications, up to 1 MHz frequency range. Not only due to its reduced transit time, but also by its low forward-voltage drop and low leakage current, making it possible to increase the output voltage and DC ripple of power supplies with greater efficiency.A Schottky barrier diode can also be used as an efficient switch in modern peltier coolers. In these systems, the diode performs two basic functions: it prevents a reverse current when the system is switched on and off, protecting the peltier cells, and it decreases the voltage across the peltier cells, resulting in a longer lifespan and overall cooler operation.In addition, this type of diode is frequently used to protect electrical circuits from overvoltage. Known as Transorb, a special kind of bi-directional transient-voltage-suppression (TVS) diode, it is commonly used to protect inputs or outputs from electrical overshoot, spikes or transients.The BAV199W-7 use a very low on-state resistance, which reduces power consumption when compared with other types of semiconductor devices. This is particularly advantageous for electromechanical and electronic systems that must comply with energy efficiency standards, allowing them to achieve the required performance with downsized and cost-effective components.
