TVS diodes, or transient voltage suppressor diodes, are used in many diverse applications to help protect electronic components from voltage spikes. The DF3A6.8CT (TPL3) is a surface mount bi-directional Transient Voltage Suppression device specifically designed to protect portable electronic devices from electrical transients. The device is designed to protect the sensitive electronics of portable electronic devices or electronic components, such as computer motherboards, from voltage spikes due to electrostatic discharge (ESD), lightning, and other sources. It is also used to provide protection against induced transient over-volage.

Application Field of DF3A6.8CT(TPL3):

The DF3A6.8CT(TPL3) is designed to protect portable devices from over-voltage. This device is applicable for use in personal computers, notebooks, cellular phones, electronic digital cameras, portable hard drives, chargers, PDAs, and other electronic components. The DF3A6.8CT(TPL3) is designed to meet the requirements of the IEC61000-4-2, ESD and other requirements. It is compliant with the RoHS standard, and is therefore suitable for use in environmentally friendly electronic products.

Working Principle of DF3A6.8CT(TPL3):

The DF3A6.8CT(TPL3) is designed to limit the voltage across the device to a maximum of 6.8V. The device works by using a zener diode in reverse biased configuration. When the voltage across the device exceeds the specified threshold value, the diode conducts current in a reverse direction, causing the voltage to be limited.

The zener diode also helps to absorb the surge current and limits the voltage across the device by providing a low-impedance path for the current. The DF3A6.8CT(TPL3) has an excellent transient response due to its very fast reaction time and low capacitance. It is also able to tolerate large surge currents of up to 500A and has a range of measurement points, making it suitable for use in a wide variety of applications.

The device has been designed to be highly reliable, with an operating temperature range of up to125°C. It is also designed to have a very high surge protection capability with a minimum of 4kV of external ESD protection and 5kV of internal ESD protection.

The DF3A6.8CT(TPL3) is suitable for use in a wide range of power applications, from consumer electronics to automotive applications. It is also suitable for use in a variety of voltage environments, from AC to DC. The device is RoHS compliant, and is therefore suitable for environmentally friendly applications.
