Diodes - Rectifiers - Single

For power applications, a single diode rectifier can be employed as a fast rectifier in both low and high power applications. As their name implies, single diode rectifiers use a single diode to convert alternating current (AC) electricity into direct current (DC) power. They are generally employed in uni- or bidirectional current control circuits. Single diode rectifiers are often used in applications such as power supplies, power conversion, and power line regulation.

SK14-TP (SMB5819) is a high voltage single diode rectifier, offering high power density and low power consumption. With high-speed switching response and a wide input voltage range, this diode features voltage ratings up to 200V and a blocking voltage of 1200V.

Application Field

SK14-TP (SMB5819) is an excellent choice for applications that require fast rectification, such as off-line converters integrated with power supplies. It is also ideal for applications such as AC-DC and DC-DC converters, as well as high-speed switch mode power supplies (SMPS) and motor drives.

Working Principle

SK14-TP (SMB5819) works on the principle of conduction or the electric current flowing through a conductor. The device works by using an alternating current (AC) source and a diode to rectify the waveform. When an AC waveform is applied to a diode, it only allows the current to flow in one direction, converting AC electricity into DC electricity. As the positive side of the waveform reaches the anode (positive side of the diode), the diode conducts, allowing electric current to flow. As the waveform moves to the negative, the diode is reverse-biased, and it becomes an open circuit, blocking current from flowing. This process, known as full-wave rectification, converts the alternating waveform into a pulsed DC, which is then usually regulated.

Conclusion

SK14-TP (SMB5819) single diode rectifier is an excellent choice for applications that require fast rectification and power optimization. With high-speed switching response and wide input voltage range, this diode provides high power density and low power consumption. In addition, its low forward voltage and low reverse leakage current make it a perfect choice for power applications such as power supplies, power conversion, and power line regulation.
