Orga BV electrical components Germany Orga BV model Orga BV price

Orga BV electrical components are accessory products used to achieve electrical connections, classified industrially within the category of connectors. As industrial automation levels rise and industrial control requirements become increasingly strict and precise, the usage of terminal blocks has gradually increased. With the development of the electronics industry, the scope of application for terminal blocks has expanded, and their varieties have multiplied. The most widely used types, in addition to PCB board terminals, include hardware terminals, nut terminals, spring terminals, and others.

Orga BV electrical components principle

A generator can convert mechanical energy into electrical energy, and a dry cell can convert chemical energy into electrical energy. Generators and batteries themselves are not charged; their two poles respectively possess positive and negative charges, which generate voltage (current is formed by the directional movement of charges under the action of voltage). Charges inherently exist in conductors; to generate current, it is only necessary to apply voltage. When a conductor is connected to the two poles of a battery, positive and negative charges are released to generate current. When the charges are depleted, the charge is exhausted and the current (voltage) disappears. Dry cells and similar devices are called power sources. A device that converts alternating current into direct current through transformers and rectifiers is called a rectified power supply. Electronic devices capable of providing signals are called signal sources. A crystal transistor can amplify the signal sent from the preceding stage and transmit the amplified signal to the subsequent circuit. For the subsequent circuit, the crystal transistor can also be regarded as a signal source. Rectified power supplies and signal sources are sometimes also referred to as power sources.

Orga BV electrical components structure

The structure and materials of new high-voltage Schottky diodes differ from those of traditional Schottky diodes. Traditional Schottky diodes are formed by the contact between metal and semiconductor. Metal materials such as aluminum, gold, molybdenum, nickel, and titanium can be selected, while the semiconductor is typically silicon or gallium arsenide. Since electrons have higher mobility than holes, to achieve good frequency characteristics, N-type semiconductor material is selected as the substrate. To reduce the junction capacitance of the Schottky diode and increase the reverse breakdown voltage without causing excessive series resistance, a high-resistance N- thin layer is usually epitaxially grown on an N+ substrate. It is well known that there are a large number of conductive electrons inside a metal conductor. When metal contacts a semiconductor (with the distance between them being on the order of atomic size), the Fermi level of the metal is lower than that of the semiconductor. At the sub-levels corresponding to the conduction band of the semiconductor within the metal, the electron density is lower than the electron density in the conduction band of the semiconductor. Therefore, after contact, electrons diffuse from the semiconductor to the metal, causing the metal to acquire a negative charge and the semiconductor to acquire a positive charge. Since metal is an ideal conductor, the negative charge is distributed only within a thin layer on the surface with atomic-scale thickness. For N-type semiconductors, the donor impurity atoms that lose electrons become positive ions and are distributed over a larger thickness. The result of electron diffusion from the semiconductor to the metal forms a space charge region, a built-in electric field, and a potential barrier, with the depletion layer located only on the N-type semiconductor side (the entire barrier region falls on the semiconductor side). The direction of the built-in electric field in the barrier region points from the N-type region toward the metal. As thermionic emission increases the built-in field, the drift current, which is opposite to the diffusion current, increases, eventually reaching dynamic equilibrium and forming a contact potential barrier between the metal and the semiconductor, known as the Schottky barrier. When the external voltage is zero, the electron diffusion current equals the reverse drift current, achieving dynamic equilibrium. When forward bias is applied (i.e., positive voltage to the metal and negative voltage to the semiconductor), the built-in field is weakened, the potential barrier on the semiconductor side is lowered, and a forward current from the metal to the semiconductor is formed. When reverse bias is applied, the built-in field is strengthened, the potential barrier height increases, and a small reverse current from the semiconductor to the metal is formed. Therefore, like a SBD and PN junction diode, it is a nonlinear device with unidirectional conductivity.
