TVS Diodes are electronic components used to protect electrical circuits. They are connected across input and output lines in order to clamp voltage and protect the circuit from over-voltage and electrical stresses. The 30KPA71A-HRA is an example of a TVS diode and is commonly used in applications such as automotive, consumer electronics, computers, telecommunications, and industrial electronics. In this article, we will discuss the application field of the 30KPA71A-HRA and its working principle.

The 30KPA71A-HRA is a bidirectional TVS diode designed for applications requiring a surge current of up to 3.5kA. With a clamping voltage of 70V, the 30KPA71A-HRA offers superior transient voltage protection, up to four times higher than traditional suppressors. Additionally, the 30KPA71A-HRA offers a low breakdown voltage, an 8/20µs surge capability, and is capable of dissipating up to 1.2W of ESD energy.

The 30KPA71A-HRA is designed for EMI suppression in a wide variety of applications, such as automotive, consumer electronics, computers, telecommunications, and industrial electronics. In automotive applications, the 30KPA71A-HRA can be used for Powertrain, Body Electronics, HV/EV, and Aftermarket applications. In consumer electronics applications, the 30KPA71A-HRA can be used to protect against spikes and surges in other consumer electronics such as audio equipment, gaming consoles, and digital TVs. Additionally, the 30KPA71A-HRA is commonly used for computers, telecommunications, and industrial electronic applications, providing protection to electronic components and circuits.

The 30KPA71A-HRA works using the same principles as other TVS diodes. It uses a thyristor, or a voltage-sensitive device, to detect when the voltage exceeds a certain threshold, usually the rated clamping voltage. Once the voltage reaches the threshold, the thyristor switches on and forms a low-resistance path, allowing the current to be diverted to ground. As a result, the voltage across the diode is limited and the circuit is protected.

The 30KPA71A-HRA is a reliable and efficient TVS diode and is suitable for a wide range of applications. It offers high surge current capability, low breakdown voltage, and is capable of dissipating up to 1.2W of ESD energy, making it an ideal choice for protecting electronic components and circuits from surges and spikes. With its superior transient voltage protection, the 30KPA71A-HRA is an ideal choice for automotive, consumer electronics, computers, telecommunications, and industrial electronic applications.
