CDBB2200-HF

A CDBB2200-HF is a single rectifier diode, designed for high operation frequencies. It is mainly used in applications such as industrial automation, power systems, and electronic controllers. This type of diode is ideal for applications where high efficiencies and fast turn-on are essential.

The CDBB2200-HF improves on conventional rectifiers by having a higher current handling capability and lower resistance. This helps reduce power loss and achieves higher overall efficiency. It also has a wider forward voltage range, making it suitable for applications in higher voltage power systems.

The CDBB2200-HF is made up of a P-type substrate and an N-type epitaxial layer, along with a metal electrode bonded to the surface. It has a built-in N-channel MOSFET that provides an optimized on-resistance. A built-in ESD protection circuit also helps to maintain high-reliability and low EMI radiation.

The CDBB2200-HF has a wide range of applications, including DC/DC converters, battery chargers, AC/DC power supplies, and power management circuits. It has the ability to operate up to frequencies of 1.2 GHz and has a low reverse recovery time of 7 ns. This allows for high levels of power conversion efficiency and fast response.

The working principle of the CDBB2200-HF is relatively straightforward. When no voltage is applied, the diode is in the “OFF” state, meaning no current can pass through. When a voltage is applied, the diode’s N-type layer and P-type substrate form a nonconducting junction. This prevents current from passing through the diode. But when the voltage increases further, the junction’s resistance decreases, allowing current to flow.

The CDBB2200-HF is a useful device for a wide range of applications. Its advances in current handling capacity, wide operating frequency range, and low-power loss make it an ideal choice for high-frequency, low-power circuit applications.
