SD175SC100A.T Application field and Working principle

The SD175SC100A.T is a rectifier diode with a single configuration. Specifically, it is a fast recovery, silicon rectifier diode. It is a high-power, high-efficiency diode used in applications where reverse voltage and power dissipation are exceptionally high. The SD175SC100A.T is particularly well-suited for rectification and voltage regulation in harsh environments.

Package Type

The SD175SC100A.T is available in a TO-220 package. This is a versatile and popular package size, and it is compatible with a wide range of mounting configurations. The TO-220 package can tolerate high temperatures, vibrations, and other environmental factors. Additionally, it is well-suited for automated assembly methods, making it ideal for mass production.

Application Field

The SD175SC100A.T is most commonly used in AC/DC rectification and voltage regulation applications. It is particularly well-suited for applications with reverse voltages higher than 100V. This includes automotive UPS systems, solar panel inverters, voltage converters, and other power supplies. Additionally, it is often used in welding systems, air conditioners, industrial motors, and LED drivers.

Working principle

The SD175SC100A.T is a silicon rectifier diode with a single configuration. It works by allowing electrical current to flow in one direction, while blocking current from flowing in the opposite direction. The forward voltage drop, which is the voltage across a diode when current is flowing through it in the forward direction, is typically 0.7V. The reverse leakage current, which is the current that flows when reverse voltage is applied, is typically very low.

The SD175SC100A.T has a maximum average forward current of 175A and a maximum peak reverse voltage of 100V. Additionally, it has a relatively low thermal resistance, making it well-suited for applications with high power dissipation. The diode is capable of operating at temperatures up to 175°C with a maximum storage temperature of 225°C.

In summary, the SD175SC100A.T is a fast recovery, single configuration, silicon rectifier diode. It is most commonly used in applications such as voltage regulation, AC/DC rectification, and power supplies. Its unique combination of features makes it well-suited for harsh environments.
