163CMQ080 Application Field and Working Principle

Diodes are semiconductor devices used to allow electricity to flow through only one direction while rectifiers are electronic circuits that convert alternating current (AC) to direct current (DC). Arrays are multiple, independent electronic components connected together in the same package. The 163CMQ080 is an application field specific to diodes, rectifiers and arrays.

163CMQ080 Application Field

The 163CMQ080 is typically used in the automotive industry, in applications such as engine control, power steering, powertrain, HVAC, and climate control modules. It is a diode/rectifier array with four diodes connected in a bridge rectifier configuration. All four diodes are contained in a common package that includes a full shore base and a heat-dissipating slug. The unit is designed to provide voltage protection and current conduction in peak current ratings up to 3A.

163CMQ080 Working Principle

The 163CMQ080 is designed to take an AC signal and rectify it into a DC signal. The device consists of four diodes connected in a bridge configuration. All four diodes are contained in a common package that includes a full shore base and a heat-dissipating slug. When AC power is applied to the input terminals of the device, each alternate half-cycle is blocked by two of the diodes and the expected outputs are achieved. One output lead from the device is connected to the positive rail and one output lead is connected to the negative rail.

When the positive half-cycle of the AC input is applied, diode D2 and diode D3 conduct and become forward biased, while diode D1 and diode D4 are reversed biased and cut off the current. As a result, a positive output is obtained at the positive output terminal and a negative output is obtained at the negative output terminal. During the negative half-cycle, diode D1 and diode D4 conduct and diode D2 and diode D3 are reversed biased and cut off the current, resulting in a positive output at the positive terminal and a negative output at the negative terminal.

Conclusion

The 163CMQ080 is a diode/rectifier array with four diodes connected in a bridge rectifier configuration. It is typically used in the automotive industry, in applications such as engine control, power steering, powertrain, HVAC, and climate control modules. The device is designed to take an AC signal and rectify it into a DC signal, with peak current ratings up to 3A. The 163CMQ080 is an example of the use of diodes, rectifiers and arrays in a specific application field.
