TPD4E002DRL2 Application Field and Working Principle

TVS (Transient Voltage Suppressor) diodes are used to protect electronic equipment from over-voltage. They are used to protect both AC and DC circuits from damaging over-voltage transients. Commonly, these transients are caused by lightning strikes, electrostatic discharge (ESD), or inductive switching. The TPD4E002DRL2 is a low-capacitance, unidirectional TVS diode used to protect data and communication lines, such as USB, HDMI, Ethernet, and IEEE1394 from transients and voltages in excess of the specified limits of the standard. In this article, the application field and working principle of the TPD4E002DRL2 will be discussed.

Application Field of TPD4E002DRL2

The TPD4E002DRL2 is a low-capacitance, unidirectional TVS diode used to protect data and communication lines, such as USB, HDMI, Ethernet, and IEEE1394 from transients and voltages in excess of the specified limits of the standard. It has an 8-pin datasheet package and operates at the maximum ratings of working voltage up to 8V and maximum clamping voltage up to 33V maximum. The TDP4E002DRL2 is suitable for suppressing ESD, lightning, and other high-voltage spikes up to the maximum clamping voltage. Despite its low capacitance, the TPD4E002DRL2 can dissipate up to 40 Amps of peak pulse current.

Working Principle of TPD4E002DRL2

The TPD4E002DRL2 is designed to protect a circuit from transients and over-voltage spikes. It contains a PN-junction diode connected in parallel between two pins of the datasheet package. This PN-junction diode acts like a switch and turns off when the voltage applied between the two pins exceeds a certain threshold. When the voltage exceeds the threshold, the junction quickly shuts off, blocking the current flow and protecting the circuit. Under normal operating conditions, the PN-junction diode remains closed, allowing current to flow.When an over-voltage surge occurs, the voltage across the two pins will increase rapidly. This rapid increase causes the PN-junction diode to turn off, preventing current from flowing between the two pins. This, in turn, prevents the surge from damaging the device. The protection is limited, however, as it won\'t protect the device from surges larger than the ordering voltage of the diode.

Conclusion

The TPD4E002DRL2 is a low-capacitance, unidirectional TVS diode designed to protect data and communication lines from transients and voltages in excess of the specified limits of the standard. It is suitable for suppressing ESD, lightning, and other high-voltage spikes up to the maximum clamping voltage. The PN-junction diode acts like a switch and turns off when the voltage exceeds a certain threshold, preventing over-voltage transients from damaging the device.
