TVS - Diodes

Introduction

TVS (transient voltage suppressor) diodes are devices used to protect circuits from voltage transients (surges) due to lightning, automotive or industrial noise, and other inductive or electrostatic discharge events. They effectively limit voltage transients to a safe level by conducting current away from the protected device. TVS diodes are also known as surge protection diodes, because they are designed to prevent overvoltages from exceeding a certain level. TVS diodes are usually incorporated into circuit designs to protect components from overvoltage events.

MMAD1104E3/TR13 Application field and Working Principle

The MMAD1104E3/TR13 is a common TVS diode. It is a unidirectional bi-directional type, which provides protection against electrostatic discharge (ESD) events. This diode can be used in combination with other components such as varistors, ceramic capacitors and film capacitors to protected against ESD and surge events. It is suitable for use in automotive and other power electronics applications.

The working principle of the MMAD1104E3/TR13 is that an overvoltage event will be detected by the reverse diode, and the current will flow through the diode. As the voltage increases, the diode will turn on and begin to draw more current. The diode will then be forced into a highly conductive state, and will effectively clamp the overvoltage to a safe level. The voltage will then drop back down to its original level.

The MMAD1104E3/TR13 diode is a good choice for automotive applications, as it can withstand multiple ESD events as well as surge events. It also has a very low clamping voltage, which helps to reduce power dissipation. Its reverse recovery time is short, allowing for fast response to transient events. The device also has low capacitance, which helps to reduce the generation of high frequency noise that can be generated by other ESD protection components.

Conclusion

The MMAD1104E3/TR13 is a reliable, robust, and cost-effective TVS diode from Semtech. It offers excellent protection against transient events such as ESD, lightning, and power line surges. The device has a low clamping voltage, low capacitance, and a fast reverse recovery time, making it a great choice for automotive and other power electronics applications.
