DH20-18A

Introduction of DH20-18A Rectifier

DH20-18A is a high power single-phase rectifier diode with a rated repetitive peak reverse voltage of 20V and a rated repetitive peak forward current of 1.8A. This rectifier diode is usually mounted on a printed circuit board, and has a low forward voltage drop, low forward current, high efficiency and low temperature coefficient.

Working Principle of DH20-18A

DH20-18A is a standard rectifying diode, meaning it can conduct current in one direction, but not the opposite direction. It is typically used in a bridge rectifier.

A bridge rectifier is a circuit made of four diodes connected in a bridge formation. It takes an AC input, such as the kind produced by a power outlet, and converts it to a DC output, such as what a battery supplies.

The four diodes in DH20-18A are connected in a bridge shaped circuit, two facing to the left and two facing to the right. The AC voltage is supplied to the bridge and each diode will conduct current when the voltage of the AC voltage exceeds the forward voltage of the diode.

When one diode is conducting current in one direction, the other diode will be conducting current in the opposing direction. This creates a continuous flow of current in one direction, which is a DC output.

Applications of DH20-18A Rectifier

DH20-18A is a popular choice for general-purpose applications such as power conversion, motor control, and industrial equipment.

It is often used in automotive applications such as engine control, power windows, and battery charges. It is also used in power supplies for AC-DC conversion, battery charging, and LED light drivers.

This diode can also be used in communication systems, where it provides a safe amount of current to ensure reliable data transmission.
