TVS - Diodes - MPLAD36KP300A Application Field and Working Principle

Transient voltage suppressors (TVS) diodes maximize protection for electrical and electronic components from fast, damaging voltage transients. Among all TVS diodes, one of the most common is the MPLAD36KP300A. This article covers the basic application fields and how this device works when used in electronic protection schemes.

Uses and Application Fields

The MPLAD36KP300A is an uni-polar TVS diode with an operating voltage range up to 36 V. Generally, this device is used for protecting sensitive electronic components from transient voltage spikes caused by the inductive load switching, electrostatic discharge and switching power supply application. A wide variety of applications use the MPLAD36KP300A for its effectiveness in protecting circuit components, including cars, industrial machineries, electrical appliances, office machines, and consumer electronics.

Working Principle

The working principle of the MPLAD36KP300A is to sense spikes in voltages that surpass its maximum operating voltage (36 V) and create a conductive path for the current flowing through it. By shunting the energy from the transient voltage spikes from the protected circuit, the MPLAD36KP300A reduces the stress seen by the components and allows them to operate as designed. Under normal operating conditions, the diode is biased so that it is in the OFF state, thus offering minimal current flow between the anode and the cathode. If the voltage across the diode surpasses the diode’s maximum operating voltage, the device will become forward biased and it will start to conduct. This will allow the device to shunt the current to ground and thus protect the circuit.The MPLAD36KP300A is a uni-directional transient voltage suppressor which means that it offers the same amount of protection only to one side of the circuit. This means that if the transient voltage spike comes from the cathode side, then the device will not provide any protection. For this reason, it is often recommended to install two devices in series.

Conclusion

As a transient voltage suppressor (TVS) diode, the MPLAD36KP300A is highly effective in providing protection to sensitive electronic components from spikes in voltage caused by inductive load switching, electrostatic discharge, and switching power supply applications. The device is designed with a maximum operating voltage of 36 V and provides unidirectional current flow to ensure a secure and reliable condition. Its working principle lies in shunting the energy from the transient voltage spike to the ground, thus offering full protection to the connected components.
