SR202 R0G

Introduction

The SR202 R0G is a single-phase bridge rectifier manufactured by IXYS Corporation. It is composed of four switching elements, two diodes and two resistors, and is designed to minimize the rectified voltage drop and reduce power consumption. This type of rectifier is commonly used in power supplies, instrumentation, and medical, telecommunications, automotive, and industrial applications.

Applications

The SR202 R0G is primarily used in power supplies that require a regulated, filtered output. It is also used in motor control, battery charging, and computer monitor applications. The device is useful in a wide variety of applications, including instrumentation, where it is used to provide a clean, DC/DC current; automotive, to minimize the ripple and minimize transient ringing; and medical, where it is used to reduce power consumption and improve operation speed.

Working Principle

The working principle of the SR202 R0G is derived from the four individual components in the circuit, the two switching elements and two resistors. The switching elements are responsible for converting the alternating current (AC) voltage into a direct current (DC) voltage. The diodes act as rectifiers, enabling the junction of the two resistors to switch between the two states of the AC voltage. The resistors act as a limiter, preventing the DC output voltage from surpassing its rated maximum.

The SR202 R0G is designed to minimize the voltage drop across the rectifier while providing a low noise output. This is accomplished by allowing one diode in the bridge to conduct while the other diode is in the off state. Since a single diode is conducting, the current flow is relatively constant which reduces power consumption and voltage drop significantly.

Advantages

One of the primary advantages of the SR202 R0G is the low power consumption and small package size. Compared to other rectifier designs, the SR202 R0G has a smaller package size and lower power consumption. This reduces the cost and complexity of the power supply design.

The SR202 R0G also has a high temperature operating range from -25°C to 85°C, allowing it to suitable for use in a wide range of environments and applications. The device is also capable of up to 2500V surge without damage, making it suitable for use in applications where the peak voltage exceeds the nominal rated voltage.
