The BAR28 is a type of single-phase full-wave silicon rectifier diode that has been specifically designed to handle high voltage, high current rectification applications. It is a low noise diode, with a peak surge current of 30A. This diode is designed to be used in a wide range of applications which require high accuracy rectification. The BAR28 has a maximum forward voltage drop of 0.9V and a reverse voltage of 1000V. It has a reverse current of 10A and an operating temperature range of -55°C to 125°C.

The BAR28 is commonly used in the power conditioning devices such as automatic voltage stabilizer (AVR) circuits, voltage regulator circuits, and power converters. It is also used in low frequency rectification circuits, as well as in switching power supplies. This diode is ideal for use in robust circuits that require precise operation and high efficiency. Other applications include: plasma lighting systems, free-wheeling protection, and AC/ DC circuits.

The BAR28 features a unique construction that enables it to provide maximum efficiency and precision in rectifying AC power to DC power. This diode utilizes two high-quality gallium arsenide (GaAs) chips that are connected in series. This construction provides the diode with a higher breakdown voltage, better noise performance, and improved surge current ratings in comparison to conventional diode structures. The GaAs chips also enable the diode to achieve extremely fast switching times, resulting in improved performance in switching power supplies.

The BAR28 works by allowing current to flow in one direction only when it is forward biased. When evenly conditioned AC power is applied to the forward current terminals of the diode, the GaAs semiconductor chips reverse-bias each other, allowing the current to pass only in one direction. This helps to regulate the flow of current, effectively converting AC power to DC power. After the current passes through the chips, the capacitor attached to the diode\'s reverse current terminal prevents any back-flow of current and reduces the level of noise.

In summary, the BAR28 is a high-performance single-phase rectifier diode that is specifically designed to handle high voltage and high current rectification applications. This diode is made from a unique construction that allows it to provide maximum efficiency and accuracy in the rectification process. It is capable of withstanding high temperatures, providing low noise performance, and providing improved surge current ratings in comparison to conventional diode structures. The BAR28 is largely used in power conditioning devices such as AVR circuits and power converters, as well as in switching power supplies, plasma light systems, and AC/DC circuits.
