Introduction to CDBUR0145

CDBUR0145 is a single-phase 45V avalanche rectifier diode from the CDBUR series. This series offers 1.05A of average output current. CDBUR0145 has a typical thermal resistance of 9.7°C/W and a maximum current of 1.3A. It features a maximum surge current of 8.25A and a maximum repetition rate of 150kHz.

Application Field of CDBUR0145

CDBUR0145 is primarily used for switching DC power in applications that require high surge current capability, such as LED drivers, high power electronic ballasts, automotive electronic systems, and telecom switching power supplies. Additionally, CDBUR0145 is also suitable for circuit protection, AC switchover, and peak current limiting in various electronic systems.

Working Principle of CDBUR0145

CDBUR0145 is an avalanche rectifier diode, which means that it has the ability to handle high current and voltage surges without exceeding its rated peak inverse voltage (PIV). When reverse-biased, the diode responds to the rising voltage by quickly producing a high electric field. This electric field causes the passage of reverse current, which is referred to as avalanche breakdown. This phenomenon serves to protect the diode from being damaged by excessively high voltages.

In addition to avalanche breakdown, CDBUR0145 also features diode recovery, which is the device\'s ability to return back to its normal non-conductive state after a high surge or overload. The diode is fully recovered when the voltage drops to a predetermined level. This helps the diode remain reliable under a range of operating conditions, with minimal decrease in performance.

Conclusion

CDBUR0145 is an excellent choice for applications that require high surge current capability and fast diode recovery. With its typical thermal resistance of 9.7°C/W, maximum current of 1.3A, and maximum surge current of 8.25A, the CDBUR0145 is an efficient and reliable rectifier diode for the protection and switching of DC power.
