Working Principle

The CDBMF160-HF is a low-profile and fast-acting diode rectifier with a very low forward voltage drop, making it ideal for high-frequency switching. The diode has an integral filament which is activated by a control terminal, allowing it to resist high peak currents and switching speeds when the voltage is applied. The diode is designed to handle variations in temperature and voltage which help to maintain its performance despite changing conditions. The ESSOP package of the CDBMF160-HF makes it useful for applications that require a very small form factor.

The CDBMF160-HF works by allowing current to flow in only one direction—from the anode to the cathode—as it blocks current from the other direction. Its low-profile design and fast-acting characteristics allow it to be used in high-frequency switching applications, whereas its low forward voltage drop makes it suitable for a wide range of power supply and conversion applications. With its integral filament, it is capable of dissipating heat for power switching components and devices, ensuring their reliable operation.

The CDBMF160-HF also offers excellent thermal performance due to its ESSOP package design and has a maximum junction temperature rating of 175°C. This allows it to be used in higher temperature and voltage applications without being damaged. The diode also offers a very low reverse leakage current, providing protection against overcurrents. Its very low forward voltage drop and low junction temperature rating make the diode suitable for a wide range of high-frequency applications, including power supplies, rectifier circuits, and converters.
