Application Field and Working Principle of 3N251-E4/45

Diodes are widely used in modern electronics and electrical circuits. An essential component of any diode is the Bridge Rectifier. The 3N251-E4/45 is a four-terminal Bridge Rectifier manufactured by Diodes Incorporated. This diode features compact size, low voltage drop and low leakage current, making it ideal for many different industrial and consumer applications.A Bridge Rectifier is an electronic component that is used to convert an alternating current (AC) signal into a direct current (DC) signal. The 3N251-E4/45 Bridge Rectifier consists of four diodes connected in a closed loop to form an AC to DC converter. The four terminals are designated as anode, cathode, anode stop and cathode stop, with the anode and cathode being the two input terminals and the anode stop and cathode stop being the two output terminals.The 3N251-E4/45 has a forward voltage drop rating of no more than 1.690 volts and a leakage current rating of no more than 1.5 mA at a reverse voltage of 1.5 V. This combination of low voltage drop and low leakage current results in an efficient and reliable output.The 3N251-E4/45 has a maximum forward current rating of 1.1 A and an operating temperature range of -55°C to +150°C. These properties make the diode well-suited for many different industrial and consumer applications, such as in power supplies, LED lighting, low voltage motors, AC/DC power converters, and automotive electronics.The Bridge Rectifier works by allowing current to flow through the two input terminals and blocking current from flowing through the two output terminals. This creates a “bridge” between the two input terminals, and the two output terminals. When an AC signal is applied to the two input terminals, the four diodes in the Bridge Rectifier circuit alternately turn into a forward and reverse direction to create a rectified signal. This rectified signal is then applied to the two output terminals, resulting in a DC signal.The 3N251-E4/45 Bridge Rectifier is an ideal component for many applications due to its low voltage drop, low leakage current and wide operating temperature range. It is an efficient and reliable component for power supplies, LED lighting, low voltage motors, AC/DC power converters, and automotive electronics.
