RB085B-90TL Discrete Semiconductor Products

The RB085B-90TL is a series of high-voltage surface mount schottky barrier rectifier diodes packaged in SOT-23, SMA and surface mount molded plastic packages. This series of diodes is available in a variety of forward current ratings ranging from 0.25 amps to 10.0 amps.

Schottky barrier rectifiers are used in many different types of applications. Commonly they are used as a switching device, such as in power supplies, voltage regulators, and polarity converters. They are also used to provide overvoltage protection, improve signal-to-noise ratios, and reduce ringing in signal lines.

The RB085B-90TL is a high-voltage schottky barrier rectifier array which features a common anode configuration and epitaxial construction. The device is designed to provide high thermal dissipation through its extended power contact design. The array is designed to have excellent electrical performance and low forward voltage drop.

The working principle of the RB085B-90TL is based on the rectification of alternating current. A schottky barrier rectifier is composed of a metal-semiconductor junction which prevents the current from flowing away from the junction when the applied voltage is reverse-biased. When the applied voltage is forward-biased, the current flows in only one direction allowing the diode to act as a rectifier.

When the RB085B-90TL is used in an application, the diode assembly is connected to two terminals: the anode and the cathode. The anode is the positive terminal and is connected to the power supply. The cathode is the negative terminal and is connected to the load. When the applied voltage is greater than the threshold voltage of the diodes, current will flow from the anode to the cathode, rectifying the applied alternating current into unidirectional current.

The RB085B-90TL can be used in a variety of applications including high-voltage power supplies, voltage regulators, polarity converters, bridge circuits, and surge suppressors. It can also be used in applications requiring low forward voltage drop and high thermal dissipation.

In conclusion, the RB085B-90TL is a high-voltage schottky barrier rectifier array with a common anode configuration and extended power contact design which provides excellent electrical performance and low forward voltage drop. It is suitable for a variety of applications requiring high-voltage rectification, including power supplies, voltage regulators, polarity converters, bridge circuits, and surge protectors.
