Diodes, also called semiconductor diodes, are the main components of electronic circuit devices. Diodes act as electronic switches, allowing current to flow through a circuit in one direction only. A single diode, such as the AU3PKHM3/86A, is used in a wide range of applications. This article explains the application field and working principle of the AU3PKHM3/86A.

Applications

The AU3PKHM3/86A is a single diode that can be used in various applications. It is used in power rectification, protection circuits, free-wheel circuits, converters, and in power electronic drives. It is also used as an electronic regulator for voltage switching and polarity protection. The diode is also used in pulse shaping circuits, data processing circuits, and in other switching applications.

Working Principle

The AU3PKHM3/86A works by creating a low resistance path in one direction and a high resistance path in the other. This allows current to flow in only one direction while blocking current in the opposite direction. When the voltage reaches the breakdown voltage, the diode becomes forward biased and a low resistance current path is created. The voltage at which the diode begins to conduct is known as the breakdown voltage, also sometimes called the avalanche or zener voltage.

At the reverse breakdown voltage, the diode stops conducting, creating a high resistance path for current in the reverse direction. The reverse breakdown voltage is typically much higher than the forward breakdown voltage. The forward voltage drop, Vf, of the AU3PKHM3/86A diode is typically around 1.2V at current levels up to 5A.

The reverse current for the AU3PKHM3/86A is typically very low. In reverse bias mode, the diode can block high voltages up to 1000V. The peak forward surge current can exceed 2A and the forward power dissipation can exceed 400mW in some applications.

Conclusion

The AU3PKHM3/86A is a single diode used in a wide range of applications. It works by creating a low resistance path in one direction and a high resistance path in the other, allowing current to flow in only one direction while blocking current in the opposite direction. The AU3PKHM3/86A offers a maximum forward voltage drop of 1.2V, low reverse current, and high voltage blocking of up to 1000V. This makes it an ideal choice for power rectification, protection circuits, free-wheel circuits, converters, and other switching applications.
