Single diodes, also known as rectifiers, are electrical components that allow electrical current to pass through in one direction while reversing all other signals. The FR202TA, manufactured by ON Semiconductor, is a single diode produced to provide a higher level of noise immunity and lower levels of power dissipation than its predecessors. This component is ideal for use in medium-voltage applications and other applications that require high-speed switching. In this article, we will discuss the FR202TA single diode application field, its working principle, features, and other specifications.

FR202TA Application Field

The FR202TA is a single diode designed for the full-speed switching process of medium-voltage applications (up to 400V) such as lamp dimmers, low-frequency and high-voltage motor control, adjustable speed drives, inverters, and general feedback control systems. It is also suitable for applications that require a low threshold voltage, such as a polarity protection, battery and line isolation circuits, and tuning capacitors.

FR202TA Working Principle

As a single diode, the FR202TA is designed to limit the current flow through the component. This is accomplished by passing an electric field of reverse bias over the junction of the two regions of the semiconductor material, creating a potential difference between the two regions. This potential difference creates a strong repulsive force that prevents the flow of electrons from the cathode to the anode.

When a small voltage is applied across the diode, a current output is created, allowing current flow to pass in one direction. In the opposite direction, the repulsive force created by the electric field is sufficient to prevent the current flow, which provides the rectification for voltage and current. The FR202TA features high-speed switching, providing faster response times for current to pass. This makes it highly suitable for applications such as servo motors and model aircraft.

FR202TA Features and Specifications

The FR202TA is designed to handle up to 400V and provides a lower operating temperature range compared to other models. It also has a lower forward voltage drop and an improved level of ESD protection. Additionally, the FR202TA has an average forward current of 5A, reverse leakage of less than 5A, and a capacitance of less than 12pF.

In terms of size and weight, the FR202TA is one of the smallest and lightest single diodes available. It is available in a TO-252 package and weights approximately 1.4g. The FR202TA is also RoHS compliant, making it an ideal choice for applications in the industrial and military sectors.

Conclusion

The FR202TA is a single diode designed for use in medium-voltage applications requiring high-speed switching and improved noise immunity. It has a fast response time, low ESD protection, high operating temperature range, and other specifications that make it an ideal choice for servo motors, model aircraft, and other applications. With its small size and low weight, the FR202TA can be easily integrated into a wide range of application designs.
