ME700803 Application Field and Working Principle

The ME700803 is a silicon bridge rectifier that is commonly used in power supply circuits, battery charging systems, and DC motor control circuits. It has an isolated case which helps to provide a direct electrical connection between the two parts of a circuit, while also providing electrical insulation.

As a bridge rectifier, the ME700803 works by converting alternating current to direct current. The unit contains a bridge rectifier formed from four diodes. When the unit is connected to an AC voltage source, one pair of the diodes will conduct current while the other two will be reverse biased. This allows current to pass through the diode bridge in one direction, producing a unidirectional current flow.

The ME700803 has a peak reverse voltage (PRV) of 800 volts and a forward current of 8 amps. This makes it suitable for medium-power applications, such as those used in battery charging systems and DC motor control circuits. It also has a high repetitive peak reverse voltage, allowing it to be used in applications where a higher level of power is needed.

Unlike many other bridge rectifiers, the ME700803 has an isolated case. This helps to provide a direct electrical connection between the two parts of a circuit, while also providing electrical isolation. This can help to reduce interference, noise, and other electrical effects which may be caused by a direct connection between the two parts of a circuit.

Another advantage of the ME700803 is its relatively low forward voltage drop. This means that it can be used in applications where a low voltage drop is required, such as those used in battery charging systems and DC motor control circuits. It also has a low power dissipation, making it more efficient than many other bridge rectifiers.

Overall, the ME700803 bridge rectifier is a useful device for a wide range of applications, including power supply circuits, battery charging systems, and DC motor control circuits. It has a high forward current and a low forward voltage drop, while also providing electrical insulation and isolation. This makes it an ideal choice for many applications.
