RB085B-90GTL are single rectifier diodes designed for use in short-circuit protection and free-wheeling applications. They have a maximum current rating of 2.5A, a forward voltage drop as low as 0.8V, and a reverse voltage of 90V. The RB085B-90GTL is commonly used in automotive electrical systems, automotive alternators, generators, power supplies, and power converters.

Rectifier diodes are semiconductor devices with two connections, or an anode and a cathode. In their normal or forward-biased state, they allow current to flow in a single direction. As the current flows, the voltage drop across the diode is a relatively small amount, typically between 0.8V and 1.2V. By contrast, when a diode is reversed-biased, virtually no current passes through it. A rectifier diode’s reverse voltage tolerance is the maximum amount of reverse voltage that the diode can withstand without breaking down.

The RB085B-90GTL is capable of handling up to 90V in reverse-biased conditions without breakdown. This makes it highly suitable for use in circuits with high reverse voltages and environments where the incoming voltage may fluctuate considerably. Its low voltage drop even in forward-biased conditions make it ideal for use in power supplies with high current demands.

The RB085B-90GTL also has excellent transient protection characteristics. This means that in the event of a short-circuit, the diode will limit the amount of current that passes through the circuit and protect other components from damage. This feature is particularly useful in automotive circuits, where the risk of short-circuits is higher than in other environments.

Another application of the RB085B-90GTL is in free-wheeling circuits. Free-wheeling circuits, also known as flyback protection circuits, are a type of protection circuit that prevent the reverse-biased voltage across a diode from rising above a certain level. This is accomplished by connecting the diode across a capacitor, which absorbs the energy of the voltage spike and prevents it from harming the components in the circuit. The RB085B-90GTL is particularly suited to this type of application due to its excellent tolerance for reverse voltages, as well as its ability to handle high currents.

Overall, the RB085B-90GTL is an excellent choice for a variety of applications, including automotive electrical systems, generator circuits, power supplies and power converters, as well as free-wheeling and short-circuit protection circuits. Its wide range of features, such as high current tolerance, low forward voltage drop, and excellent reverse voltage tolerance, make it well-suited for a variety of high current applications.
