The CDBB260-HF diodes are part of the single rectifier family and are used for general-purpose rectification and freewheeling in a selection of applications. It is ideal for low-frequency power supplies, DC-DC converters, on-board chargers, snubber circuits, and LED lighting.

This diode features an ultra-low forward voltage drop that optimizes system efficiency and a high surge current rating capability that provides improved reliability against unforseen surges and transients. It is made of an axial leaded package that are suitable for through-hole mounting.

The CDBB260-HF is a silicon epitaxial construction rectifier diode that has an average forward current of 260A and a maximum repetitive peak reverse voltage of 600V. It has a low-forward voltage drop of 0.32 V at 10 A, an engineered avalanche current of up to 25A, and a peak reverse current rating of 300mA. Furthermore, it has a maximum junction temperature of 150°C and a storage temperature range of -55°C to +150°C.

The CDBB260-HF works by allowing electric current to flow in one direction. When the anode voltage is higher than the cathode voltage, it will become forward-biased and will allow electric current to pass through. An N-type semiconductor is formed in front of the P-type semiconductor, allowing electrons from the N-type to pass through to the P-type. When the anode voltage is not greater than the cathode voltage, the diode is reverse-biased, the current will not flow.

The CDBB260-HF is predominantly used to protect a circuit from fluctuations in voltage or current and to provide stable power to various types of electronic applications. It can be used in power supplies and converters, such as 12V DC to 220V AC inverters, uninterruptable power supplies (UPS), in DC-DC converters, and in car audio systems. It is highly efficient and provides optimal performance in both low and high frequency applications.

The CDBB260-HF is ideal for LED lighting applications, providing improved reliability against surges and transients. Its low forward voltage drop and fast switching times allow for high efficiency current regulation, thus reducing the power consumption of LED modules. It can be used in a wide range of LED lighting and display driver circuits, such as in laptop backlights, monitors, and automotive headlight control circuitry.

The CDBB260-HF also has snubber circuit uses. Snubber circuits are used to protect sensitive electronic components from high-frequency noise generated by transistors, resistors, and inductors. They help reduce the unwanted noise that can cause electrical damage, electromagnetic interference (EMI) issues, and excessive power consumption. The CDBB260-HF, when connected in parallel with a resistor and capacitor, acts as a snubber circuit, ensuring the integrity of the protected components and increasing the reliability of the system.

The CDBB260-HF diode is a reliable and efficient single rectifier, providing optimal performance in a range of applications, including power supplies, DC-DC converters, on-board chargers, LED lighting and display drivers, and snubber circuit protection. Its low forward voltage drop and fast switching times guarantee improved system efficiency. Furthermore, its high surge current capability ensures reliability against unexpected surges and transients, providing durability and reliable performance.
