MBRH12020R

Diodes - Rectifiers - Single

The MBRH12020R is a device from the class of rectifier diodes, which are one of the most commonly used components in power electronics. These components are used to convert alternating current (AC) electricity into direct current (DC) electricity. In the case of the MBRH12020R, it is a high-current diode designed for use in applications where any power dissipation is a problem. The MBRH12020R is a pin-compatible alternative to the MBRH12020L, a low-current diode. This versatile device offers various advantages in terms of quality, cost, and performance.

Application Field

The MBRH12020R is used in a wide range of applications, from automotive to power converters, and from cell phone chargers to low-voltage AC-DC power supplies. This device is suitable for applications where high power dissipation is a problem, thanks to its low package thermal resistance. The MBRH12020R is also suitable for a variety of rectifier circuits, such as switched mode power supplies (SMPS), as well as buck, boost, and flyback DC-DC converters that typically operate in the range of 1-50 kilovolts.

The MBRH12020R is also suitable for high-frequency, high-temperature conditions, such as diode rectifier stacks, where its thermal resistance is beneficial in reducing power stress effects. The device features an impressive power handling capability of 25 kW and is available in the widely used TO-220AB package.

The MBRH12020R is a temperature compensated Schottky diode that is reliable, efficient, and cost effective. It is widely used in applications such as automotive headlamps and motor vehicle power converters, motor drives, inverters, and communications and telecoms systems for direct rectification.

Working Principle

The MBRH12020R works using a simple principle: when alternating current (AC) electricity flows through the diode, it is converted into direct current (DC) electricity. The device works by allowing and blocking electrical current from passing through it. When voltage is applied, the device allows limited current to flow through it, while blocking the rest. When the voltage reaches a certain level - defined by the device\'s forward voltage drop - the diode becomes "forward biased" and conducts almost all of the current.

The MBRH12020R uses Schottky diode technology, which offers a low voltage drop and fast switching characteristics for high-frequency rectification. This diode is designed for use in applications where high power dissipation is a problem, thanks to its low package thermal resistance. It is also capable of operating at high frequencies and in high-temperature conditions.

The MBRH12020R is a temperature compensated Schottky diode that offers excellent performance and reliability, and is suitable for use in applications where high power dissipation is a problem. It offers fast switching with a low voltage drop, making it an ideal choice for rectification in a variety of applications.
