Diodes - Rectifiers - Single

R7000204XXUA is one kind of single rectifier diodes featuring low reverse leakage current, fast switching time, high power efficient and low power loss. It has seen applications in electronic rectification and low voltage rectifiers. Its wide application includes on-board components in DC power supplies, welding power supplies, battery chargers, charging circuit and switching power supplies, etc.

Working Principle

First of all, when a dielectric material is placed between two different types of materials, which are connected respectively to two oppositely charged electrodes, an external voltage applied to these two electrodes will produce an internal electric field in the volume of the dielectric material. This material is referred to as a resistor and its resistance to the flow of current is determined mainly by the size and shape of the dielectric material.

When the voltage across the resistor is increased, the resistance of the diode increases. When the voltage exceeds the threshold voltage, a break down of the diode occurs, allowing current to flow. The voltage at which such breakdown occurs, is known as the breakdown voltage. In terms of the R7000204XXUA, the breakdown voltage is typically between 4 and 5 volts.

In a way, a diode can be seen as an electronic valve, as two-thirds of the voltage across the diode is across the anode and only one-third of it is across the cathode. The anode is the positive terminal of the diode, and the cathode is the negative terminal. When a voltage is applied to the diode, the anode is positive with respect to the cathode. As such, current only flows through the diode in the positive direction, effectively blocking the the flow of current in the reverse direction.

Application Field

Due to its rapid switching time and high power efficiency, R7000204XXUA diodes have been found in a range of applications in power electronics. These diodes demonstrate low reverse leakage current which makes them suitable for use in low voltage rectifiers. The use of these diodes are beneficial if high current flow needs to be limited, as the low on-state resistance of the diodes keeps the current at desired levels.

R7000204XXUA diodes are commonly used to construct on-board components for power supplies. The fast switching times of the diode allows for the efficient transfer of DC power, and the low power loss helps to maintain optimal efficiency. This makes R7000204XXUA diode perfectly suited for use in DC power supplies, welding power supplies and battery chargers.

These diodes are also found in switching power supplies. Thanks to their fast switching time between anode and cathode, R7000204XXUA can effectively switch power on and off. This allows for an efficient operation of the power supply, as only the current that is necessary is employed when required.

Conclusion

In conclusion, R7000204XXUA diodes have many applications in both power electronics and low voltage rectification circuits due to their fast switching times, low reverse leakage currents and low power loss. As such, R7000204XXUA diode is an invaluable component for building efficient power supplies, battery chargers, charging circuits and switching power supplies.
