PMEG3005EH, 115 Application Field and Working Principle

PMEG3005EH, 115 diodes belong to the category of rectifier diodes. These are unidirectional devices, which means that they only allow current in one direction. The condition of rectification is that the voltage should be greater than its reverse breakdown voltage, otherwise it will not pass. These diodes are manufactured by a process called diffusion, wherein the active region of the diode is formed in an epoxy package. These are single diodes.

Applications of PMEG3005EH, 115 Diodes

PMEG3005EH, 115 rectifier diodes are highly useful in power supply systems and other electrical circuits. They are employed in rectifier applications where the output needs a low-forward voltage drop. These diodes have an average forward current of 0.115A, and they are resistant to repetitive forward current pulses. They are ideal for applications requiring high power and high current. They are also well suited for rectification of ac voltages, where the ripple voltage must be kept to a minimum.

Working Principle of PMEG3005EH, 115 Diodes

The principle of operation of these diodes is based on the laws of electrical conduction. The diode consists of two regions, the anode, and the cathode. In the case of a forward-biased diode, an electric field is developed in the junction region between the anode and the cathode. This electric field reduces the potential barrier, which then allows a current to flow. The number of such carriers generated by the electric field further increases the current level.

The reverse-biased diode works in the same way, but this time, the electric field is established in the opposite direction, making it difficult for the current to flow. The barrier potential thus increases and the current level decreases. This makes the diode a one-way medium.

The PMEG3005EH, 115 diodes can also be used to build rectifier bridges. In a rectifier bridge circuit, the power necessary for rectification is supplied to the center terminal, and the current flows from both the anodes to the center. This helps to reduce the peak power demands of the system and also provides additional safety as any single diode failure will not cause the system to fail.

Conclusion

PMEG3005EH, 115 diodes are single rectifier diodes that are very useful for rectifying ac voltages. They have a low forward voltage drop and can handle high currents. They are employed in a variety of applications, including power supply systems and rectifier bridges. Their operation is based on the laws of electrical conduction.
