SR302-T

Introduction

SR302-T is a single, common anode rectifier diode designed for use in commercial applications. It has the high-performance properties expected of a high-end rectifier diode, optimal for commercial applications. The device has been designed with a maximum current rating of 4A, a VF reverse voltage rating of 75V, and an on-state voltage drop of less than 1V.

Application

The SR302-T is suitable for use as a rectifier in telecommunications, networking and industrial power supply. The device is typically used in multiple-terminal applications, such as bridge rectifier or loose-diode configurations, for ripple and noise reduction in telecom, industrial and switchmode power supplies. It can also be used in the rectified portion of automotive, switching and audio power amplifiers, and in audio frequency power amplifiers.

Benefits and Features

• Low on-state voltage drop (VF) and low forward resistance (Rf)
• High-speed switch-on and switch-off capability
• God thermal stability and surge resilience
• High reliability
• High current handling capability (4A)

Package Options

The SR302-T is available in TO-220 and SOT-89 packages, each of which offers different levels of performance. The TO-220 package has a thermal resistance of 39.4°C/W from the junction to the tab and a maximum operating temperature of 150°C. The SOT-89 is smaller and provides up to 60% space savings. The thermal resistance of the SOT-89 package is 23.2°C/W from the junction to ambient. Both packages come in 4-pin configurations.

Working Principle

The SR302-T rectifier diode is a two-terminal device that converts alternating current (AC) to direct current (DC). It works on the principle of reverse biasing of a p-n junction, in which current only flows in one direction, known as the forward bias direction. The forward voltage drop of the diode has a very low value, usually less than 1V, and the reverse voltage is usually less than 75V, making it ideal for commercial applications.

When a voltage is applied in the forward bias direction, the diode conducts current, allowing the flow of electric charges. When a voltage is applied in the reverse direction, the diode blocks the flow of electric charge, thus restricting the flow of current. The SR302-T is designed to handle a high reverse voltage, ensuring reliable operation in a variety of applications. The device also has a high forward current rating, making it suitable for high-current commercial applications.

Conclusion

The SR302-T is a good high-performance diode designed for use in commercial applications. It has a wide range of applications and offers many benefits, such as low forward voltage drop, high current handling capability, and low thermal resistance. In addition, its package options are designed to provide space and thermal management when used in a variety of applications.
