SRA1690HC0G is a kind of rectifier for the application of many areas, and thus it is an important component of many electronic products. This article is prepared to introduce its application field and working principle.

As a diode, the main application of SRA1690HC0G can be the rectification of AC to DC. Thus, the SRA1690HC0G rectifier is widely applied in the power supply of electronic products, such as television sets, earphones, hair dryer and so on. Besides, the rectifier is also used as the controlling module in a few automotive control systems. With the controlling module, the motor can switch on and off automatically to reduce the energy cost.

In terms of the structure, SRA1690HC0G rectifier is a kind of silicon rectifier. It consists of outer package and the inner chip which take the form of metal plate. The metal plate mainly consist of four parts: anode, cathode, junction and metal parts. The junction of the anode and cathode is the p-n junction of the rectifier, and it is the part where the rectification occurs. The metal parts along the sides of the junction are connected to the anode and cathode to form two loops as the application of passing electric current.

The working principle of the SRA1690HC0G rectifier is that, when the ac voltage is applied to the input, the positive and negative half wave will push the current in different directions in different cycles. Consequently, the electrical current stores in the metal sheet and discharges, thus forming the rectified DC output. Besides, the p-n junction is the part that carries out the rectification process and prevents the forward current from flowing backward. That’s why the diode works as the rectifier.

To sum up, the SRA1690HC0G rectifier is widely used as a power supply and controlling module in many electronic products such as TV sets, earphones, hair dryers and automotive control systems, due to its stable performance. Its working principle is that the p-n junction of the rectifier carries out the rectification process, and the metal plate provides the electrical current with a loop to form a DC output.
