Diodes - Rectifiers - Arrays are components that are used for converting alternating current (AC) to direct current (DC). This can be achieved in several ways and one of the most popular diodes used for this purpose is the F1857RD1400. This diode array has a low voltage drop, a large junction capacitance, a reliable power-on reset, an overvoltage protection, and reverse-blocking capability.

The F1857RD1400 consists of four individual MOSFETs (Metal Oxide Semiconductor Field Effect Transistors) – two N-channel and two P-channel MOSFETs – in a single package. It is a dual-channel full-bridge rectifier diode that provides a rated voltage range of up to 140 volts and a diode current rise and fall times of less than 70 ns. It also has an on-resistance of less than 0.02 ohms when conducting and an off-state leakage current of less than 0.2 µA.

The F1857RD1400 is typically used in several applications, such as automotive on-board chargers, battery chargers, DC converters, industrial equipment, power adapters, and power supplies. The diode array is designed to handle high-current signals, typically up to twenty amps, by connecting the MOSFETs in parallel for increased current capability. Additionally, it provides isolated power supply, due to its high on/off input impedance, which helps to reduce the design of power control components, such as capacitors and inductors.

In terms of working principle, the F1857RD1400 diode array functions as a switch by reversing the two MOSFETs back and forth. When the voltage is into a low level, the two N-channel MOSFETs turn on consecutively and this causes current to flow through the device producing a DC output. On the other hand, when the voltage is into a high level, the two P-channel MOSFETs turn on consecutively and this causes current to flow in the opposite direction and producing a DC output in the opposite polarity.

In conclusion, the F1857RD1400 is a full-bridge rectifier diode that is designed and optimized for providing high-current signals with fast switching times, high on/off input impedance and exceptional power-on reset performance. It is used in several applications, such as automotive on-board chargers, battery chargers, DC converters, industrial equipment, power adapters, and power supplies and it works by reversing the two MOSFETs back and forth in order to produce a DC output.
