Applications

The D255N02BXPSA1 is mainly used in applications where rectification is required, especially for power systems or where RPP is needed. It is used for rectification of simple analog AC waveforms, for conversion of ac waveforms into DC waveforms, for rectification of complex waveforms, and for RPP. This part has many applications in the telecom industry, such as protection of telephone lines from transient voltage, protection of RF amplifiers from reverse polarity, and power supply design.

Working Principle

The single rectifier diode works by utilizing the principle of PN junction diodes. PN junction diodes allow current to flow in one direction only, and this is the basis for the rectifier diode’s function. When the anode of the diode receives a positive voltage, the PN junction diode starts to conduct and allows current to flow. The reverse voltage is blocked and is not allowed to pass, protecting the active part from further damage. The output behaves like a square wave with the positive and negative peaks having the same amplitude, thus producing a rectified wave. The ripple in the output waveform is caused by the finite switching time of the diode.

The D255N02BXPSA1 is a low-power rectifier diode, and this has applications such as powering low-voltage power supplies, bridge rectifiers and circuit protection. This part has a low forward voltage drop (VF) of 1.5 Volts, and a low total power dissipation (PD) of 2.25 Watts. It also has a low junction capacitance (CJ) of 3.2 pF. This makes it suitable for low-voltage applications and small form factor rectification solutions.

The D255N02BXPSA1 is a very versatile diode and can be used in a wide range of applications. It can function as a high-speed rectifier and it can be used in PFC rectifiers and DC/DC converters. It can also be used in low-power rectifier circuits, and it is a cost-effective solution for many end-user applications.
