TVS - Diodes ( transient voltage suppression diodes ) are a kind of semiconductor device that have the ability to protect electronics from dangerous voltage spikes. The MXPLAD36KP28AE3 is one such device that offers superior protection against voltage transients in electronic systems. In this article, we will discuss the application field and working principle of the MXPLAD36KP28AE3.

The MXPLAD36KP28AE3 is a unidirectional device that is mainly used in the protection of automotive electronics from voltage spikes. It has an operating voltage of 36 Vdc and a peak pulse power of 2.8 kW. The device features a low clamping voltage (Vcl), a low dynamic impedance (Zz), a fast response time (trr) and a high storage temperature (+125°C). These characteristics make it ideal for automotive applications, such as engines, airbags, infotainment systems, transmissions, batteries, alternators, starters and traction controllers.

The working principle of the MXPLAD36KP28AE3 can be understood by looking at its structure. The device features an electroplated cathode, an electrode array, and an anode. The electroplated cathode is attached to the silicon substrate and acts as the gate voltage. The electrode array consists of two sets of electrodes - one for the low-voltage, high current protection level, and one for the high-voltage, low current protection level. The anode is connected to the substrate and allows for a current flow through the device when a voltage spike occurs.

When exposed to a sudden voltage spike, the electroplated cathode acts as a gate voltage, switching the device from a non-conductive to a conductive state. This causes the device to absorb the spike, reducing both its amplitude and duration. The electrode array then filters out the excess voltage and current, providing an efficient, effective level of protection against voltage transients. The anode then allows for a safe and controlled current flow to ground, preventing damage to the protected system.

The MXPLAD36KP28AE3 is a highly reliable device that can effectively protect automotive electronics from voltage spikes. Its low clamping voltage, low dynamic impedance and fast response time make it perfect for automotive applications. Additionally, its high storage temperature allows it to be used in extreme temperature environments, such as engine compartments or underhood locations. In conclusion, the MXPLAD36KP28AE3 is an ideal solution for protecting automotive electronics from dangerous voltage transients.
