MX15KP240A

TVS diodes (commonly known as transil diodes), also known as surge protection devices (SPDs) are electrical components that provide protection from sudden and potentially damaging surges of electrical energy. The MX15KP240A is a popular TVS diode in the international market, widely used in industrial, medical and military applications.

The MX15KP240A is a Uni-Polar device, meaning that it is designed to operate in a single polar configuration, meaning it can only handle current in one direction. It has a peak power rating of 15 kW and can handle voltages of up to 240V, making it a highly suitable Surge Protection Device for medium voltage applications. This type of diode is usually employed in order to protect electronic components from voltage spikes, electrical waves, or lightning strikes.

The MX15KP240A does not possess any mechanical parts; instead, it is a monolithic semiconductor package which includes four diodes in a two-line configuration. The diode’s high surge capability is enabled by its high surge current ratings, and high surge voltage resistance due to the physical structure design. The improved structure, along with its novel blocking voltage range, mean the diode can absorb much of the current of a sudden spike. Therefore, it is ideal for circuit protection at terminals, in junction boxes and fields.

The MX15KP240A works according to the Avalanche Breakdown Principle. During an electrical surge, the diode’s enhanced, high surge current rating allows it to rapidly switch on and absorb the extra energy. The surge current instantly creates a high electric field intensity in the junction. This causes the diode’s current to increase rapidly and avalanche breakdown occurs. The avalanche breakdown is a strong form of current conduction through the diode junction, and it helps to reduce the voltage. This reduces the surge voltage, thus protecting the electronic circuit from any potential damage.

The MX15KP240A is suitable for use in a wide range of applications, including industrial, medical and military. It is mostly used on systems which require medium voltage protection. Its main advantages include a wide operating temperature range (up to 150°C) and high surge current rating. Additionally, it is an affordable solution for many protection applications.

In summary, the MX15KP240A is a popular and effective TVS diode designed to provide surge protection for medium voltage applications. It works according to the Avalanche Breakdown Principle and can handle voltages of up to 240V and temperatures up to 150°C. Additionally, its high surge current capacity makes it an optimal choice for many circuit protection applications.
