MPLAD36KP70CA Application Field and Working Principle

TVS (transient voltage suppressor) diodes are a type of diode designed for protecting sensitive electronic components from voltage spikes or transients. The MPLAD36KP70CA is a gas discharge tube (GDT) TVS diode manufactured by Littelfuse. It has a low breakdown voltage and can handle peak pulse current of up to 80A. In this article, we will discuss its application field and working principle.

Applications of the MPLAD36KP70CA

The MPLAD36KP70CA is primarily used in applications such as automotive, commercial, professional, and Industrial, where voltage transients are expected and high-speed switching circuits are used. It is also used in medical equipment, military, aerospace, computer, and telecom applications. The GDT provides very fast, accurate, and consistent protection across a wide range of applications. It also reduces the risk of damage caused by voltage spikes.

As the MPLAD36KP70CA is a low breakdown voltage TVS diode, it is ideal for applications that require low clamping voltage and strong pulse current handling capabilities. Its peak handling current of 80A makes it suitable for high-speed switching applications. It is also low-power and can operate within a wide temperature range. These factors make it suitable for applications such as motor controllers, switches, voltage regulator modules (VRMs), and point-of-load (PoL) converters.

Working Principle of the MPLAD36KP70CA

The MPLAD36KP70CA is a Gas Discharge Tube (GDT) TVS diode, which uses a small gas-filled tube as the switching element for protection. The tube consists of two electrodes, one of which is connected to the anode of the diode and the other connected to the cathode. The tube is filled with a noble gas, such as argon or nitrogen, and contains a small amount of mercury vapor. The electrodes are insulated from each other to ensure that there is no direct electrical conduction between them.

When a voltage transient is sensed by the diode, the voltage across the tube increases to a point where the avalanche breakdown of the noble gas occurs, resulting in a low resistance path between cathode and anode. This reduces the voltage across the device and protects the circuit from spikes. The gas discharge tube has a very fast responding time and can respond to voltage transients within microseconds.

The MPLAD36KP70CA has an ultra-low breakdown voltage of 6.5V, making it suitable for applications that need very low clamping voltage. It also has a peak current handling capability of 80A. This makes it suitable for high-speed switching applications. The diode also offers minimal power consumption and operates within a wide temperature range. These features make it suitable for use in a wide range of applications.

Conclusion

The MPLAD36KP70CA is a GDT TVS diode manufactured by Littelfuse. It is used in a wide range of applications such as automotive, industrial, medical, military, aerospace, computer, and telecom. The diode has a low breakdown voltage and a peak current handling capability of 80A. It is also low-power and can operate within a wide temperature range. The working principle of the diode involves an avalanche breakdown of the noble gas inside the GDT tube, which provides a low resistance path between the anode and cathode and reduces the voltage across the device. The MPLAD36KP70CA is well-suited for use in high-speed switching applications and in applications that require low clamping voltage.
