Introduction

TPSMA6.8AHE3_B/H is the type of TVS - Diodes, a kind of two-terminal solid-state devices designed to protect circuits against electrical transients such as surge, induced noise, spikes, and ESD. TVS - Diodes play the role of circuit protector, which is widely used in many industrial applications.

Application Field

TPSMA6.8AHE3_B/H can meet different requirements of different devices. Generally speaking, it is mainly used to protect the electronic circuits which are including computers, communications, peripherals, relays, motors, power converters, sequential logic ICs, AC power line, data lines, and grounding wires, and etc., from overvoltage generated by automotive and power loads, as well as from fast transients and ESD (Electro-Static Discharge). Besides, it is developed to protect sensitive electronic components from transient events such as lightning, switching load transients and electrostatic discharge (ESD).

Working Principle

The working principle of TPSMA6.8AHE3_B/H is simple. As voltage exceeds the breakdown voltage of the device, the TVS - Diode starts to conduct and clamps the voltage to a predetermined level. When the transient event is over, the TVS - Diode turns off and is ready to provide further protection circuits against further transients.

The reverse breakdown voltage and the peak pulse current ratings of TPSMA6.8AHE3_B/H determine the ability of the device to clamp and protect downstream electronics. For example, if the applied transient voltage exceeds the TVS - Diode’s breakdown voltage, the diode will turn on quickly and divert the current away from the power rails, thus preventing voltage surges and reducing the likelihood of device damage.

Packages and Mounting

The TPSMA6.8AHE3_B/H is supplied in a compact surface mount package with a low profile design. As this package is much smaller than conventional TVS - Diodes, it allows higher density designs. Furthermore, the adjustable mounting scheme also permits flexibility in the layout design of the printed circuit board. The device is soldered by reflow soldering method, which guarantees a long-term reliable and secure connection.

Conclusion

TPSMA6.8AHE3_B/H is a type of TVS - Diodes which can effectively protect electronic devices against electrical transients such as surge, induced noise, spikes, and ESD. It is widely used in automotive and power loads, as well as in various industrial applications. By providing clamping voltage, it can generally improve the reliability and safety of circuits.
