Diodes - Bridge RectifiersA bridge rectifier is an electrical circuitry composed of diodes that is used to convert an alternating current (AC) input signal into a direct current (DC) output signal. In other words, a bridge rectifier changes the alternating current input into a unidirectional pulsating direct current output. For example, the B485H-2T rectifier can be used to convert a 110V AC voltage from a home outlet into a 12V DC power supply.The B485H-2T is a 4-terminal bridge rectifier that provides high ratings at 120A peak. It is popularly used in automotive, industrial, and consumer electronic products, making it a versatile and reliable choice. It utilizes two opposing junctions of the diode to achieve its power conversion. The two junctions (i.e. the anode and the cathode) complete the bridge circuit, allowing electricity to flow in one direction while preventing it from flowing in the opposite direction. This process is known as rectification.Furthermore, the B485H-2T is designed to limit transient voltage generated when switching power supplies. It can also handle continuous overloads to prevent damage from occurring to the circuit due to high currents. Additionally, it is designed to minimize reverse-recovery time for optimum performance.Generally speaking, bridge rectifiers are helpful in providing clean and smooth DC power, unlike the AC voltage outputted by conventional power supplies. They also enable efficient return paths for currents in the situation that the load current is more than the supply current. In addition, they produce a “bell-shaped” pulsating line voltage that can be attenuated by adding a filter to the circuit.For its application, the B485H-2T is most suitable for use in direct current (DC) motor speed control, automotive electronics, transformers and welding circuits, voltage regulators, and secondary rectification such as for dimming lighting or digital voltmeter metering. It is also an apt choice for use in exposed or specialized environments that require heightened resistance to temperature and humidity.In terms of its general physical characteristics, the B485H-2T has an operating temperature range of -55°C to 175°C and a storage temperature from -55°C to 250°C. It also has Solder Resistance to significantly reduce mounting stress and protect against short-term high temperature static currents. It is a 4-terminal bridge that is typically housed in a rectangular shaped plastic case with bolt connectors for easy assembly.Moreover, the B485H-2T rectifier provides excellent heat dissipation thanks to its patented heat radiation design which disperses heat generated from the high currents accordingly. As such, it is capable of withstanding under voltage and over temperature conditions as well. Finally, its bridge configuration makes it ideal for providing a full wave output current, even in the presence of an AC ripple current.Overall, the B485H-2T bridge rectifier is a reliable, time-tested device for converting AC into DC. Its low-resistance heating technique makes it suitable for use in outdoor and high temperature environments, while its key feature of providing smooth DC power output significantly improves the performance of applications like motor speed controlling and LED dimming. In addition, its low voltage, high current, and high frequency properties make it a great fit for residential and commercial applications alike.
