TVS - Diodes

TVS (Transient Voltage Suppressor) diodes are 2-terminal passive components specifically designed to protect electronic systems and components from overvoltage damage. They can protect against a wide range of voltages, both normal and abnormal, and provide excellent protection from electrical overstress caused by electrostatic discharge, load clearing, transmission line switching, lightning, and other surge-type events. TVS diodes are often used as a first line of defense in a power system, to provide the highest level of protection against damage caused by high voltages.

MMQA6V8T1 Application Field and Working Principle

The MMQA6V8T1 TVS diode is designed for use in sensitive electronic systems. It is a 6V diode with peak power handling capabilities of up to 600W. The reverse peak standoff voltage (V(BR)RWM) is 5.6V and the clamping voltage is 8.25V. The dynamic external clamping device (DECD) reduces the clamp voltage for voltage transients up to 500W, which makes it suitable for a wide range of applications.

The working principle of a TVS diode is based on surge suppression technology that prevents high voltage transients from affecting sensitive devices. When a surge is applied, the diode turns on and begins conducting current, which clamps the voltage at a safe level and ensures that the sensitive device is not exposed to harmful voltage levels. The diode turns off again when the surge ends and the power supply is restored to its nominal level.

In addition to its surge protection capabilities, the MMQA6V8T1 also offers filtering properties that can reduce conducted electromagnetic interference (EMI). This is achieved by filtering out unwanted high frequency signals that are generated by high frequency current pulses of the power supply. This makes it ideal for applications where sensitive electronic components need to be protected from high voltage transients and EMI.

Overall, the MMQA6V8T1 TVS diode is a highly effective device that can provide robust circuit level protection against high voltage transients for sensitive electronic components. It is an ideal choice for applications where both surge protection and EMI filtering are required.
