Transient voltage suppressors (TVS) are widely used in electronics applications, where they provide protection to circuit designs. The ESD7241N2T5G is an example of a common surface mount TVS diode designed to protect circuits from accidental electrostatic discharge (ESD) and other transient overvoltage events. This article will provide an overview of the ESD7241N2T5G application field and working principle.

Application Field

The ESD7241N2T5G is one of the most popular TVS devices used for ESD protection. The device has an ultra-low capacitance, flat clamping voltage from -0.9V to 26.8V, and an ESD rating of 8kV (HBM). It is designed as a polymer positive temperature coefficient (PPTC) device and features a low leakage current. Additionally, ESD7241N2T5G is RoHS compliant, providing an environmentally friendly solution.

The ESD7241N2T5G is suitable for use for most electronic devices, including consumer electronics, communications equipment, automotive electronics, audio/video equipment and medical equipment. The compact size and flat response make it ideal for use with modern, highspeed circuits. This device is also ideal for use in combination with high frequency, low noise circuits, as the small size helps minimize the parasitic inductance found in these types of circuits.

Working Principle

The ESD7241N2T5G is designed to protect circuits from transients caused by ESD or other sources. When a transient event occurs, the ESD7241N2T5G is triggered and a conducting path is created between the anode and the cathode. This path is able to absorb the transient energy and prevent damage to the protected circuit.

The device is made up of two parts; a ceramic disc and a conducting path. The ceramic disc is made of a special material with a high bandgap energy that is extremely resistant to electrical breakdown. When a transient event occurs, the energy is absorbed into the ceramic disc and the conducting path is activated to provide a low resistance path to absorb the excess energy.

The ESD7241N2T5G also features a low clamping voltage from -0.9V to 26.8V, providing a more efficient protection than standard TVS devices. Additionally, the low leakage current of the device ensures that the device remains in a non-conductive mode after the transient event has passed, minimizing the power consumption of the protected circuit.

Conclusion

The ESD7241N2T5G is a commonly used TVS device for ESD protection. It features an ultra-low capacitance, flat clamping voltage from -0.9V to 26.8V, and an ESD rating of 8kV (HBM). Additionally, the device is RoHS compliant, making it an environmentally-friendly solution. The ESD7241N2T5G is suitable for use in consumer electronics, communications equipment, automotive electronics, audio/video equipment and medical equipment.

The working principle of the ESD7241N2T5G is based on a ceramic disc and a conducting path. When a transient event occurs, the energy is absorbed into the ceramic disc and a low resistance path is activated to absorb the excess energy. The device also features a low clamping voltage and low leakage current, ensuring an efficient and reliable protection for the circuit.
