Introduction

TVS diodes, also known as Transient Voltage Suppression (TVS) diodes, are a series of semiconductor devices designed to protect circuits against sudden surges of voltage, current, and energy much greater than the operating voltage range of the circuit. The MPLAD18KP7.5AE3 is an example of a TVS Diode, and is used in a variety of applications. This article will explore the application field of the MPLAD18KP7.5AE3 and its working principle.

Application Field

The MPLAD18KP7.5AE3 is targeted mainly at automotive applications, such as on-board computer and powertrain systems. It has an operating voltage range of 7.5V and can effectively clamp voltages up to 800V, making it perfectly suited for applications with regularly occurring voltage peaks ranging from severe to catastrophic. Furthermore, its small outline (SO) and small-outline flat-leaded package (SODFL) give it a great advantage: its small size and low power consumption make it ideal for space-constrained applications. As a result, this device is highly suitable for automotive control and communications systems.

Working Principle

The MPLAD18KP7.5AE3 works under the principle of avalanche breakdown, which is a type of self-induced destruction that occurs in semiconductors when the electric field that is generated by the voltage applied to the semiconductor exceeds the breakdown threshold voltage of the material. When this happens, the avalanche dissipates energy as thermal energy, allowing the voltage to stay within the safe operating limits of the circuit.In addition to the principle of avalanche breakdown, the MPLAD18KP7.5AE3 also incorporates the principle of a zener diode, which utilizes the same breakdown phenomenon but with a circuit that provides a very small impedance path for current to flow through. This small current path effectively works as a clamp on the voltage, allowing it to remain stable even when the source voltage rises to levels far above what the device was designed to handle.

Conclusion

The MPLAD18KP7.5AE3 is a TVS diode designed to protect circuits from voltage, current, and energy surges. Its application field is mainly automotive systems, due to its small size and low power consumption, and its principle of operation relies on the principles of avalanche breakdown and zener diodes. It has an operating voltage range of 7.5V and can effectively clamp voltages up to 800V, making it an effective device for reliable circuit protection.
