The 1N5821HB0G is a single-phase, 200V, 3A Schottky barrier rectifier, marked with the HB0G code. It is part of a broad range of Schottky barrier rectifiers from Diodes Incorporated and is ideal for a variety of applications including power supplies, freewheeling, reverse polarity protection, and low forward voltage drop.

Rectifiers are essential components for modern power supplies where direct current (DC) output is needed for powering equipment. Rectifiers have many applications such as microprocessor-controlled power supplies, power distribution systems, motor drives, and high-efficiency electronic devices.

The 1N5821HB0G is a single-phase, 200V, 3A Schottky barrier rectifier that is capable of withstanding 100 volts of reverse biased voltage and can absorb transient surges up to 36V in magnitude. It has a forward voltage drop of 0.5V (typical at 3A) and reverse leakage current of 20 mA at 25V.

Schottky barrier rectifiers are lauded for their low forward voltage drop and ability to handle high pulsed current load at frequencies well above those of traditional rectifiers. Due to the relatively low forward voltage of Schottky diodes, these devices can provide excellent efficiency and reduce power loss in various DC applications.

In the forward conduction mode, the voltage drop across the 1N5821HB0G device is quite low, typically 0.5V at 3A, resulting in a high efficiency. It has up to 55A of maximum surge capability with a low thermal resistance of 0.8°C/W. The 1N5821HB0G also features enhanced inverse polarity protection, which can protect against damaging transient voltage in power distribution systems.

In the reverse blocking mode, the 1N5821HB0G is capable of withstanding 100 volts of continuous reverse bias voltage. In addition, it is rated to handle transient voltage surges up to 36V in magnitude. It also features a reverse leakage current of 20 mA at 25V.

The 1N5821HB0G is an ideal choice for applications such as low voltage, low power supplies and applications requiring low forward voltage drop and EMI suppression. As with all Schottky barrier rectifiers, the 1N5821HB0G provides excellent switching performance and high efficiency in rectification.

Applications for the 1N5821HB0G include freewheeling diodes for AC switches and chopper circuits, as well as reverse polarity protection for power surge applications. It is also beneficial for providing direct current (DC) isolation for high frequency DC to AC inverters, low forward voltage drop power supplies, and other high-efficiency applications.

In summary, the 1N5821HB0G is a single-phase, 200V, 3A Schottky barrier rectifier that is capable of providing excellent efficiency, low forward voltage drops, and enhanced inverse polarity protection. It is designed for a variety of applications including motor drives, low voltage and low power supplies, high frequency DC to AC inverters, and other high-efficiency applications.
