Introduction

TPSMC30AHE3_A/I are TVS – Diode devices designed for use in applications subject to high-temperature, transient interference including ESD (electrostatic discharge) and other signal disturbances. These devices provide a low capacitance and high-speed switching to limit transient interference with signals on the input or output of circuits.

Application

TPSMC30AHE3_A/I is typically used in circuit protection applications, circuit conditioning, low current protection, filtering, and switching applications. Furthermore, these devices are also used in various consumer electronics, including video game systems, mobile phones, tablet computers, laptop computers, medical diagnostic systems, and other complex electronic applications. The primary application of TPSMC30AHE3_A/I is designed to protect lines from transient voltage and current events such as electrostatic discharges (ESD), overvoltage, and overcurrent. These devices are also suitable for surge protection applications, primarily on TVs, monitors, touch-screen LCD displays, and LED displays.

Working Principle

TPSMC30AHE3_A/I is a bidirectional Transient Voltage Suppressor (TVS) diode that is designed to protect sensitive electronic circuits from transient voltage and current events. These devices are composed of two diodes connected back-to-back and integrated into a single package. When there is a voltage excursion that exceeds a specified threshold, such as a surge originating from an ESD event, the device is activated. During this time, the two diodes in the device are triggered into opposite conduction mode. The negative diode is forward-biased while the positive diode is reversed-biased. The current path follows the two connecting pins of the package, allowing a low capacitance path to the ground. The transient current is then diverted away from the sensitive components of the circuit, protecting them from damage. Once the surge exceeds a pre-determined voltage, the device also has a limited current and power limitation. This helps to further protect the sensitive components of the circuit.

Conclusion

TPSMC30AHE3_A/I is an ideal device for a wide range of consumer electronics applications. It is an excellent choice for providing Circuit Protection, Circuit Conditioning, Low Current Protection, Filtering, and Switching applications. Furthermore, it is an effective solution for protection against ESD, overvoltage, and overcurrent events.
