BAV202-GS18 Application Field and Working Principle

The BAV202-GS18 is a diode rectifier in the category of single diodes, meaning it has only one diode with two leads and it does not require any other components to function. It is made for consumer applications, as it was designed to provide a low forward drop voltage, better efficiency, and greater thermal performance than regular diodes. This rectifier can operate up to a maximum of 600V, an operating temperature of –55°C to +150°C, and it is available in different forms from a standard axial DO-214 package to an SOT-23 package, depending on the application.

The application field for BAV202-GS18 rectifiers is extensive, as it can be used in a variety of consumer-specific applications, ranging from inverters and converters to motors and light ballasts, among other things. This diode offers great reliability and performance, ensuring that the output quality of the connected device remains high.

In terms of the working principle, the BAV202-GS18 rectifier utilizes a silicon-controlled rectifier, also known as a SCR. A SCR is an electrical switch that can be opened or closed to control current flow in an application. The way that it is opened or closed is just as significant, as it needs to be triggered by a gate signal. This gate signal is provided by the voltage of the application and it is what instructs the diode to either let electricity through or not.

Looking at the symbol of the BAV202-GS18 rectifier, you can see that it follows the general conventions of a diode symbol. However, the addition of a smaller diagonal line towards the top of the symbol denotes that it is a special type of diode. This addition allows it to function as both a blocking and conducting diode, meaning it can block the current flow or direct the current flow to any application it is connected to.

The BAV202-GS18 rectifier is a powerful tool for consumer-based applications, as it was designed to provide improved performance and reliability. It has a temperature range from –55°C to +150°C, making it suitable for a wide variety of conditions, and it is available in various forms from standard axial DO-214 packages to small SOT-23 packages for applications where size is essential. The utilization of a silicon-controlled rectifier also further enhances its appeal, as it can be instructed through the gate signal to open or close the current flow of the application it is connected to, maintain quality and efficiency.
