SD101AWS-E3-18

Introduction

The SD101AWS-E3-18 is a rectifier diode offering maximum ratings of 180 V, 10 A, and 900 pF. It is housed in a robust 2-pin plastic SMT package and designed for use in a variety of applications. We will focus on the application fields and working principle of this diode in this article.

Application Fields

The SD101AWS-E3-18 is most commonly used for Uninterruptible Power Supplies (UPS) and Telecom Power Installations as it meets the requirements of infrastructure products in terms of surge current handling capability, minimum residual voltage, and fast reverse recovery time. It has also been widely adopted for other SMPS applications. The major applications for this component include:

• Power Supplies
• Battery Chargers
• Telecommunications
• Uninterruptible Power Supplies
• Power Tools
• Audio and Video Equipment

Working Principle

In a circuit utilizing the SD101AWS-E3-18, current flows through the anode when the anode is more positive than the cathode. It is the simplest form of a rectifier diode, and it works on the principle of a forward bias, which allows the current to flow from the anode to the cathode. The reverse bias occurs when the anode is less positive than the cathode, resulting in no current conduction. This is known as the reverse blocking mode.

The maximum ratings of 180 V and 10 A support a wide range of power applications. The total recovery time for the diode is about 400 ns, making it well-suited for high-frequency applications. Its breakdown voltage is rated at greater than or equal to 180 V and its maximum junction temperature is 150 °C.

Conclusion

The SD101AWS-E3-18 is a single rectifier diode with maximum ratings of 180 V, 10 A, and 900 pF. It has been widely adopted for various power applications, such as SMPS, UPS, and telecom power installations. The working principle of this diode is based on a forward bias that allows current to flow from the anode to the cathode when the anode is more positive than the cathode, and a reverse blocking mode when there is a higher potential at the cathode. It supports a wide range of power applications and has a fast recovery time of 400 ns.
