CDBA140-HF Application Field and Working Principle

CDBA140-HF is a high frequency rectifier diode which is used in multiple application fields, including standard conversion, high frequency power conversion, frequency multiplication and snubber circuits.

The CDBA140-HF has an anode (A), a cathode (C), and a gate (G), and can operate in a voltage range of 30V - 90V. It features a maximum average forward current of 125A and a maximum reverse current of 10µA. It is housed in a SMF package that measures 9.7mm x 5.5mm x 3.2mm, and has a junction temperature rating of 175°C. The CDBA140-HF features a low leakage current and a low forward voltage drop, which makes it suitable for high temperature applications.

The CDBA140-HF works on the basis of two main principles: rectification and multiplication. Rectification refers to the process of converting an AC (alternating current) signal into a DC (direct current) signal by allowing the current to flow in only one direction. This means that any AC waveform is converted into a DC signal, allowing it to be used in circuits where DC is required. The rectified signal is then multiplied in order to increase its magnitude and voltage level. The resulting waveform is much more efficient, and can also be regulated more easily.

The CDBA140-HF operates at a frequency of above 1MHz, and is capable of handling up to 175A of peak forward current. Its low forward voltage drop and low leakage current makes it suitable for applications involving high power, such as snubber circuits. Additionally, its low internal resistance ensures that it can handle larger currents without heating up, which is especially useful in high temperature applications.

In conclusion, the CDBA140-HF is a high frequency rectifier diode that is suitable for a variety of applications, including standard conversion, high frequency power conversion, and snubber circuits. It features a low forward voltage drop, low leakage current and a low internal resistance, making it ideal for use in high temperature and high power applications.
