• Communication Power Supply: In communication power supply, CR5F-040 BK is mainly used for AC-DC power rectification, so that the output power supply can meet the requirements of communication equipment.
• Electronic Instruments and Equipment: CR5F-040 BK is used as a single diode in electronic instruments and equipment. It is mainly used for electrostatic protection or current limiting protection of electronic circuits for noise reduction and overcurrent protection.
• Lighting Engineering: CR5F-040 BK is also used in lighting engineering. It is mainly used to convert AC power into DC power, to provide DC power supply, while eliminating current surges, spikes, and other power interference.

Working principle

CR5F-040 BK is a unidirectional special semiconductor device. It is composed of PN junction and metal electrode. It can only pass current in one direction and block current in the other direction. By controlling the current and voltage, the stored electric energy is released and converted into electrical energy. When the voltage of one end of the PN junction is 0.7V higher than the other end, a forward current will be generated. The higher the voltage difference is, the larger the current will be. When the voltage of one end of the PN junction is lower than the other end and there is a certain reverse voltage, a reverse current will be generated. At this time, CR5F-040 BK will enter a reverse breakdown state and become an extremely low resistance.
