EGP20KTA Application Field and Working Principle

EGP20KTA is a single diode rectifier with a maximum operating temperature of 125°C and a voltage of up to 200V. It is widely used in various applications, including voltage regulation, power regulation and other power conversion systems.

Application Fields

• Power electronics applications
• Audio, video, telecommunications and computer systems
• High-frequency power supply systems and current-mode control systems
• General-purpose switching power supplies
• Power conversion systems
• Negative temperature coefficient and overvoltage control

The EGP20KTA can be used in both AC and DC applications, making it suitable for a wide range of applications. It is also ideal for low power applications, such as those found in portable electronic devices.

Working Principle

The EGP20KTA is a diode rectifier that converts AC voltage into DC voltage. The AC voltage is applied to the anode and cathode of the rectifier. The anode of the rectifier is always positive and the cathode is negative, so when AC voltage is applied to the two terminals, the current flows in one direction only. This is due to the inherent characteristic of the diode, known as PN junction rectification.

However, when the polarity of the applied AC voltage is reversed, the current will flow in the opposite direction. This is known as reverse conduction. This is a beneficial effect, as it helps to suppress overvoltage or overload in the system.

The EGP20KTA also has a negative temperature coefficient (NTC) which helps to protect the device from thermal runaway. The amount of current flowing through the device increases with temperature, so the NTC helps to ensure that the current does not become too high, thus protecting the device from damage.

Conclusion

The EGP20KTA is a single diode rectifier that is suitable for a wide range of applications. It is suitable for AC and DC applications, and has a negative temperature coefficient to help protect it from thermal runaway. The EGP20KTA can help to reduce overvoltage and overloads in the system, making it a reliable and efficient rectifier.
