TVS – diodes are devices used to protect electronic equipment from voltage transients. They are also known as transient voltage suppressors and are widely used in many electronic circuits. The ESD8472MUT5G is an example of a TVS – diode designed for applications such as overvoltage protection, EMI filtering, and other applications. In this article, we will discuss the application field and working principle of the ESD8472MUT5G.

Application Field

The ESD8472MUT5G is a bidirectional TVS Diode able to handle transient voltages up to 5.5 V. It is designed to protect a single line from a maximum overvoltage of 5 VDC. It is also rated for a maximum clamping voltage of 14V. It can be used for bus power protection, EMI filtering, switching power supply protection, and overvoltage and ESD surge protection.

In bus power protection applications, the ESD8472MUT5G can be used to prevent damage from transient voltage spikes which can be caused by static electricity, shorts, inductive spikes, and lightning. It can also provide protection against overvoltage and ESD transients, which can cause severe data corruption and destruction of sensitive circuitry. In addition, it can be used for EMI filtering to reduce noise or interference associated with switching power supplies.

Working Principle

The ESD8472MUT5G TVS diode works by diverting the transient voltage away from sensitive components. When the TVS diode senses a transient voltage that exceeds its breakdown voltage, it acts as a short circuit and diverts the surge current away from the protected circuit. This prevents any further buildup of charge and limits the maximum voltage seen on the protected circuit. The diode then reverts to its normal high impedance state once the transient is over. Because the diode is so fast in acting, it can clamp a transient voltage and protect your system in milliseconds.

The ESD8472MUT5G TVS diode is designed to be placed in series between the positive and negative supplies of a circuit. This ensures that it can divert the overvoltage event away from the rest of the circuit. The maximum current rating of the diode limits the maximum current that it can handle, so it is important to pair the ESD8472MUT5G TVS diode with a circuit with a suitable operating current. On top of this, the ESD8472MUT5G has internal electrostatic discharge protection to guard systems from the destructive effects of ESD.

Conclusion

The ESD8472MUT5G is an excellent TVS – diode for ESD protection, EMI filtering, and other applications. It is designed to handle transient voltages up to 5.5 V and a maximum overvoltage of 5 VDC. When placed in series between the positive and negative supplies of a circuit, it can provide effective protection from voltage transients. The diode also features internal ESD protection, allowing it to protect sensitive circuitry from the destructive effects of ESD. Overall, the ESD8472MUT5G is a reliable and effective device for voltage protection and EMI filtering.
