CDBQR0130R-HF Diodes - Rectifiers - Single Application Field and Working Principle

The CDBQR0130R-HF diode is a single rectifier diode, featuring a wide operating temperature range of -65°C to +175°C and a current rating of 1A in a TO-18 (SOT-416) package with a fast turn-on time of 20ns. This diode is suitable for various applications, such as automotive, aerospace, and medical industries.

Working Principle

Single rectifiers are widely used components in electrical circuits, and their function is to allow the current in one direction while blocking it in the opposite direction. The diode structure is composed of two branches: an anode and a cathode. The anode is the positive terminal and the cathode is the negative terminal. When the anode is more positive than the cathode or is at a higher voltage level, then the diode conducts current, and when the anode is less positive than the cathode, then the diode is reverse-biased and does not conduct current. This property is known as rectification. When the diode is forward-biased, the electric field in the diode leads to the generation of hole-electron pairs in the junction. When the hole-electron pairs are reversed, the electric field in the junction is conserved and therefore, the diode will conduct. In the reverse direction, when the diode is reverse-biased, the electric field intensity of the diode is increased and the holes and electrons in the junction are repelled, making the diode non-conducting. Under normal operating conditions, the electric field in the junction area is not high enough to generate the action of valence electrons, making it hard or impossible for the diode to conduct current in the reverse direction.

Application Field

Due to its wide range of operating temperature, the CDBQR0130R-HF diode is suitable for use in automotive, aerospace and medical applications, among others. The diode’s low on-state voltage drop of 0.6V provides a high efficiency power switch and its low reverse leakage current makes it suitable for applications where there is a large difference between the positive and negative voltage. The CDBQR0130R-HF can also be used for protection against reverse-biased surges, such as in flyback converters, AC-DC and DC-DC power supplies. It is also used to reduce voltage with the help of its fast turn-on time. In addition, the CDBQR0130R-HF is suitable for snubber circuits, clamping diodes, and temperature sensing applications. It can also be used in power distribution units, power sources and stabilizers, network routers, computers, and telecommunications equipment. In conclusion, the CDBQR0130R-HF diode is a highly versatile component offering a wide range of advantages for use in automotive, aerospace, and medical industries. Its tight geometrical design and low on-state voltage drop make it an ideal choice for many applications.
