Diodes - Rectifiers - Single are electronic components that allow current to flow in one direction only. The CDBU0145 is a semiconductor diode device that employs a Schottky diode of planar configuration. It is designed to provide high voltage and low current rectification, and is suitable for applications such as power supplies, voltage regulators, and energy harvesting systems.

The Schottky diode configuration adopted by CDBU0145 provides a low voltage drop from anode to cathode, with up to 18 volts of forward biased voltage at 20mA being achievable by the CDBU0145. This contributes to higher efficiency of power supplies, voltage regulators, and energy harvesting applications that employ the diode. Additionally, the CDBU0145 has a low reverse leakage current of 200nA at 10 volts, thus reducing power loss. The reverse breakdown voltage is in excess of 75 volts.

The CDBU0145 is a surface mount device in a compact package size of 2.1mm by 1mm. This small form factor enables device designers to reduce component count within PCB designs and create integrated circuits with a larger component pitch. The SMA-2 package of the CDBU0145 is electrically insulated, making the device suitable for direct mounting on a metal heat sink or multi-layer PCBs.

The main purpose of the CDBU0145 is to act as a rectifier for high-voltage and low-current applications. The diode will conduct current in the anode-to-cathode direction and act as an insulating barrier in the opposite direction. When used in power supplies and voltage regulators, the CDBU0145 can rectify AC power into DC current, maintaining the voltage level of the power supply while filtering noise and limiting harmonic distortion. In energy harvesting applications, the diode allows solar cells, thermoelectric generators, or other energy capture devices to charge the energy storage device via rectification of the AC voltage.

The CDBU0145 features a fast switching time of 6 nanoseconds, making it suitable for use in high-frequency switching circuits. As such, it can be used in DC-DC converters, and other switching networks in both isolated and non-isolated topologies. Additionally, the diode’s low forward voltage drop of approximately 0.33V at 1A ensures that it can be employed in high-speed operations with minimum power losses. Finally, the device can be operated over a temperature range of -55°C to 125°C, which enables it to be used in high temperature power systems.

In conclusion, the CDBU0145 is a surface mount Schottky diode device suitable for a range of high voltage and low current applications including power supplies, voltage regulators, energy harvesting, and DC-DC converters. Its fast switching time and low forward voltage drop enables it to be used in high-speed and low-power applications. Its insulated package allows the substrate to be mounted on various substrates, which makes the device suitable for both simple on-board designs and complete embedded circuits. The operating temperature range of -55°C to 125°C allows the device to be used in a variety of thermal conditions. Finally, its reverse breakdown voltage of over 75 volts provides reliable protection against high voltage spikes and surges.
