TVS - Diodes

Transient Voltage Suppressors (TVS) Diodes are an invaluable device in the electronics industry. With an increasing demand for power, bigger and more powerful systems are being designed and built. This brings with it, the need for protection from electrical transients. In this article, we take a look at the 30KPA70A-HRA application field and working principle.

Introduction

TVS Diodes are general purpose transient voltage suppressors (TVS) which have been designed to protect sensitive electronic components from destructive electrostatic discharge (ESD) and surges generated by lightning and other sources. The 30KPA70A-HRA features a unidirectional breakdown voltage of 70V, low reverse leakage, fast response times, low inductance and a low capacitance interface to the user’s circuit.

Application Fields

TVS Diodes like the 30KPA70A-HRA are increasingly being used in a wide range of applications where the absolute maximum operating voltage is below 70 volts. These applications mainly include consumer electronic devices such as digital cameras and PDAs, medical products, computers and peripherals, LCD displays, and telecommunications equipment. The TVS can also be used in automotive applications, such as airbag systems, body electronics, and powertrain systems.

Working Principle

The 30KPA70A-HRA is a bidirectional TVS diode, meaning that it is capable of suppressing both positive and negative voltages. The device has two anodes, one with a higher voltage and the other with a lower voltage. When a transient spike exceeding the forward breakdown voltage (70 volts) is applied to the device, current passes through the device. This current then flows through the internal resistor and the negative and positive clamping diodes, suppressing the voltage to a safe level.

Advantages

The 30KPA70A-HRA provides superior surge protection compared to other TVS devices, making it well-suited for consumer electronic applications. The device offers high reliability and surge capability, fast response times, low clamping voltages, low capacitance, low inductance, and a low reverse leakage current. The device is also highly durable and can withstand temperatures of up to 125°C.

Conclusion

TVS Diodes like the 30KPA70A-HRA are invaluable tools for protecting sensitive electronic components from electrical transients. The device provides superior surge protection and fast response times, making it well-suited for applications in the consumer electronics, medical, and automotive industries. The device is also highly durable and can withstand temperatures of up to 125°C.
