The F1892RD1400 is a part of a Diode - Rectifier Arrays family that offers rated current of 1.4A, a peak repetitive reverse voltage of 140V, and a ultra-low reverse leakage current of 8uA at maximum rated VRRM. It is a general-purpose Silicon-based two-phase rectifier and come in a small SM8 package with creepage distance of 8.0mm. It can be used in various applications including converting AC to DC, power supply, voltage multiplier and battery charing.

The rectifier array mainly consists of an anode, a cathode, a blocking diode and a bypass diode. The rectifier operation is based on the action of the blocking diode and the bypass diode. The blocking diode provides rectification and stabilization of the voltage when the voltage is greater than the threshold voltage of the diode. The bypass diode is used to provide current conduction during a situation of negative voltage or when the diode cannot sustain positive voltage.

The blocking action of the rectifier array is determined by the breakdown voltage and the reverse leakage current of the diode. When the rectifier array is under reverse voltage, it blocks the current and does not allow current to flow. However, if the voltage exceeds the threshold voltage of the array, it will allow current to flow and the time taken for the current to flow is called the turn-on time.

The rectified voltage produced by the F1892RD1400 depends on the external circuit. Typically, the average voltage will be lower than the applied voltage due to the power lost in the diode junction capacitor. The value of the junction capacitor also affects the output voltage ripple of the rectifier. In addition, the reverse recovery time of the diode will also determine the output voltage ripple and thus the maximum switching frequency that the rectifier can handle.

The rectifiers can be used in a variety of application fields such as power supply, motor control, charging battery and converter. The power supply has to provide regulated voltage and current to the load. The F1892RD1400 can be used as a series rectifier to achieve such regulation. It can also be used in motor control applications to provide peak current during start-up. In battery-charging applications, the rectifier is used to produce a constant current for charging the battery. The rectifier can also be used in a converter to convert AC to DC.

In conclusion, the F1892RD1400 is a diode-rectifier array that offers a wide range of applications. With its ultra-low reverse leakage current, it can provide efficient and reliable rectification. It can be used in power supply, motor control, battery charging and converter applications with excellent performance.
