Transient voltage suppressors (TVSs) are components that become a vital part of many electrical and electronic systems. They protect sensitive devices from ESD, EMI, and other transients, thus ensuring reliable operation and accurate control of processes. The MPLAD36KP51AE3 is a diode in a Transient Voltage Suppression (TVS) package from NXP. This device has multiple applications and a simple operating principle.

Application Feild

The MPLAD36KP51AE3 is a Silicon diode that forms a kind of PN-junction, which makes it be able to act as a rectifier and protect circuits from voltage surge. Its specific breakdown voltage is 36V, which allows it to be widely applied in many parts. For example, it can be used in cars where excessive voltage buildup could damage expensive engine-control computers, in airplanes to reduce susceptibility to lightning-induced surges, or in factories to reduce spurious noise levels.

Apart from its surge protection capabilities, its fast response time and small size also make it suitable to use as an EMI filter, allowing it to reject common-mode and normal-mode noise in applications with switching power supplies or high-speed data communication.

Working Principle

The MPLAD36KP51AE3 is a low-capacitance Transient Voltage Suppressor. Its diode structure ensures that current can only flow in one direction, thus forming a protective shield. As the voltage increases, the diode structure reaches its limits and activates its overvoltage protection mode. In this situation, the diode turns itself off, thus preventing further voltage growth. At the same time, it absorbs the excess charge and dissipates it, reducing the current to normal levels.

The MPLAD36KP51AE3 has an operating voltage of up to 36V, a maximum conducting current of 5A, and a total capacitance of 0.2pF. As such, it can protect systems from high-amplitude, short-duration spikes in voltage. Moreover, its small size (2.3 mm × 2.3 mm) allows it to be used in almost any environment.

Conclusion

The MPLAD36KP51AE3 TVS diode has multiple applications and a simple operating principle. Its breakdown voltage of 36V and low capacitance make it suitable for use in areas with high-amplitude, short-duration spikes in voltage. It can be used as a surge protector, EMI filter, and more. In addition, its small size allows it to be used in almost any environment.
