CDBC380-G Discrete Semiconductor Products

Introduction

CDBC380-G is a rectifier diode with low reverse current. It is used in a variety of switching power supply applications, such as in bridge rectifiers and AC/DC converters. The device has a high rated maximum repetitive forward voltage of 1.25 V, which makes it particularly suited for low voltage applications. It can withstand forward and reverse voltages up to 180V and is available in both axial and DO-201 packages. This diode has a high power dissipation capability making it suitable for high frequency operation.

In this article we will discuss the general application field and working principle of the CDBC380-G rectifier diode. It is important to note that all semiconductor devices have different application and working conditions so it is important to consult the specific device datasheet for the best performance before implementing the design.

Application Field and Working Principle

The CDBC380-G rectifier diode is primarily used in application where low reverse current is required. It is ideally suited for bridge rectifier and AC/DC power supply applications, such as in telecom and UPS systems. The semiconductor is also suitable for other applications such as in automotive electronic control units, LDOs, current regulators and monitors, DC/DC converters, solar photovoltaic and LED lighting applications.

Now let’s look at the device working principle. A rectifier diode is a two-terminal, unidirectional device that works as a one-way valve which allows current to flow in only one direction. When a forward voltage is applied to the anode (positive) terminal, the device will become forward-biased and will allow current to pass through it. When a reverse voltage is applied to the cathode (negative) terminal, the device will become reverse-biased and will block current from passing through it. The CDBC380-G rectifier diode has an internal resistance known as the forward voltage drop (Vf). This Vf is created when current passes through the device and is specified in the datasheet. The diode will also have a maximum current rating, which should not be exceeded in order to avoid damaging the device.

Conclusion

In conclusion, the CDBC380-G rectifier diode has a wide application field due to its low reverse current feature. It is particularly suitable for bridge rectifier and AC/DC power supply applications. The device’s internal resistance known as the forward voltage drop (Vf) affects the current that passes through it. It is important to consult the specific device datasheet for the best performance and current rating before implementing the design.
