TVS devices are used in many different applications and one of the more popular devices is the MAPLAD18KP36CAE3. This device is a bidirectional transient voltage suppression diode array designed for protecting sensitive components and circuit boards from voltage spikes and transients.

The MAPLAD18KP36CAE3 as its name indicates, is a 36-lead dual array. It has a few features that make it ideal for ESD protection applications. It has 18 channels of ESD protection and can easily be integrated into different circuits. It also has a small form factor so that it can easily fit into a variety of circuit boards. Some of its other features, include its fast response time of less than 1ns, its ability to tolerate multiple events of −30kV air-gap discharges and a clamping voltage of 18V and a breakdown voltage of 36V.

When it comes to the applications of this device, it is mainly used for protecting input/output components from ESDs and other transients. The device is also used for secondary protection against high frequency transients such as lightning or spikes from electrical equipment. It is also suitable for automotive applications, being able to withstand temperatures from -55°C to 150°C.

When it comes to the working principle of the MAPLAD18KP36CAE3, it is quite simple. Once a voltage spike or transient is detected, the device starts to conduct current from the supply to the ground, reducing the voltage to a safe level. This is done by two components, a Zener diode and a thyristor, the latter being responsible for snubbing the spike and dissipating the energy. Once the transient voltage has been reduced, the thyristor turns off and the Zener diode smoothens the voltage so that it can reach the circuit elements safely.

In summary, the MAPLAD18KP36CAE3 transient voltage suppression diode array is designed for protecting sensitive components and circuit boards from voltage spikes and transients. It has a fast response time and can also withstand multiple events. It is mainly used for protecting input/output components, and its working principle involves the use of a Zener diode and a thyristor. It is also suitable for automotive applications due to its ability of withstanding extreme temperatures.
