Diodes - Rectifiers - Single

The CD123D-B140LR is a type of diode specifically categorized as a rectifier diode. Rectifier diodes are a class of diodes constructed to prevent electrical current from flowing in a single direction. Due to their bidirectional current, these types of diodes are particularly suited for applications that require the conversion of alternating current into direct current.

The CD123D-B140LR, specifically, is a silicon rectifier diode that was created for power rectification in automobile applications. It can generally tolerate a high current carrying capacity. Its low forward voltage drop helps decrease power loss, providing more efficient consumption of energy.

Application Field and Working Principle

A rectifier diode is an electronic component used in the field of electrical engineering. Its most common application is in a converter where alternating current is converted to unidirectional current. The operation of a rectifier diode can be divided into two processes: rectification and inverse rectification. During rectification, the diode\'s anode end is connected to a positive voltage, which increases the anode\'s potential; during inverse rectification, the anode\'s potential is decreased. Most rectifiers contain multiple diodes connected in serial or parallel. The circuits they create are mainly used to fast-switch the current from one frequency to the other.

The CD123D-B140LR is typically used for power rectification in automotive applications such as for starters, alternators, and car audio systems. It can also be used in other applications requiring power rectification, such as in power supplies, medical equipment and general consumer electronics. The CD123D-B140LR is composed of 8 individual rectifier diodes connected in a bridge rectifier format with a terminal for each anode and cathode. This diode is also able to deliver peak forward voltage drops of 175V with a diode capacitance of 0.15pF and surge withstand of 140A.

The CD123D-B140LR is designed to provide enhanced power rectification compared to other rectifier diodes. It has excellent thermal stability and a wide operating temperature range of up to 200 degrees Celsius. Thanks to its low forward voltage drop and low forward current level, it has a longer shelf life and improves power efficiency. Its improved construction helps lower diode losses and increases production yields.

Conclusion

The CD123D-B140LR is a rectifier diode suited for power rectification in automotive applications. It can tolerate a large current capacity, and its low forward voltage drop helps decrease power loss. Its improved construction and wide temperature range help prolong the shelf life of the diode and increase the efficiency of power consumption. By converting alternating current into direct current, the CD123D-B140LR helps support other electronic components in multiple kinds of applications.
