TVS – diodes are electrical devices designed to protect electronic circuits from damage caused by excessive voltages or sounds. The MPLAD30KP160AE3/TR is a model of a TVS – diode that is used in a variety of applications due to its high voltage protection range and fast response time. This article will discuss the application fields and working principle of the MPLAD30KP160AE3/TR.

Application Fields

The MPLAD30KP160AE3/TR is a transient voltage suppression (TVS) diode specifically designed for automotive applications. It has an operating voltage range of 30kV (maximum) and a peak pulse current of 160 amps per millimeter (Amm) of diode width. This makes it suitable for a wide range of automotive applications, including electronic fuel injection (EFI) systems, actuators, and switches.

The MPLAD30KP160AE3/TR is also used in consumer electronic devices. For example, it can be used in mobile phones and other handheld devices to provide protection against electrostatic discharges (ESDs). Additionally, it can be used in personal computers to protect against excessive voltages during power surges.

Working Principle

The core working principle of the MPLAD30KP160AE3/TR is gas discharge. This is achieved through the use of a specialized electrode immersed in a gas-filled chamber. When the diode is subjected to an overvoltage, the electrode emits a spark that causes the gas to ionize. This ionization results in a decrease in the diode capacitance, which absorbs the excess energy from the overvoltage and diverts it away from the circuit.

The MPLAD30KP160AE3/TR is designed to be fast acting in order to protect against surges. It has a response time of 5 to 50 nanoseconds (ns), meaning it can respond to voltage changes in a matter of nanoseconds. This makes it well suited for high-speed circuits, where fast response time is essential for protecting components from damage.

Conclusion

The MPLAD30KP160AE3/TR TVS diode is a versatile and reliable device for protecting electronic circuits from voltage transients. Its wide operating voltage range and fast response time make it suitable for a variety of applications, such as automotive components, consumer electronics, and computers. Its working principle is based on gas discharge, which quickly absorbs the surplus energy from the transient and diverts it safely away from the circuit.
