P0720EAL Circuit Protection

P0720EAL Application Field and Working Principle

Within the Thyristors family, the P0720EAL is a K-rated two-part thyristor, which has special stress characteristics. Many electronic industries use the textured emitter with a low saturation voltage rating. This low saturation voltage rating helps to control the switching speed. The P0720EAL can be used in applications with low electro-mechanical stress, and up to a maximum of 2600V.

The P0720EAL can be seen as a special type of bidirectional switch which has two distinct components. It includes both a gate and a cathode. The cathode is likewise referred to as the anode. When the gate voltage is below the conduction voltage of the cathode, the current will flow. When the gate voltage is at a level above the conduction voltage, then the current will cease to flow. In this way, the P0720EAL functions as a short-circuit switch with the possibility to control both on and off state.

When the gate voltage is raised, this means the current flow "opens up". When the gate voltage is decreased, the current flow will stop due to the greatly reduced electron conductivity as the P0720EAL ceases to turn into a short-circuit state. The number of electrons, and thus the conductivity of the device, depends on the type of application. Often, it is the positive peak current that is most important for determining the application.

The current peak is determined by a combination of the gate voltage and the anode current.The peak current is also based on the conduction angle. The conduction angle is the proportion of time at which the switch is in the “on” state. In other words, the P0720EAL can handle maximum currents limited by the conduction angle. The anode current will then reduce as the current flows through the P0720EAL device.

Since the P0720EAL is a two-part thyristor, it can also be used as a pulse-shaping device in applications with short transient events. This is due to the way it rapidly switches between its off and on states. This combination of fast switching and low voltage ratings makes the P0720EAL perfect for electronic circuits requiring pulse-shaped signals.

The P0720EAL is also perfect for applications that require a smooth switching of power, such as AC/DC power supplies. It is robust, cost-effective and is available in a wide variety of package sizes. The P0720EAL is also suitable for applications using high frequency AC currents or signals.

In conclusion, P0720EAL is an electronic switch with special stress characteristics and a low saturation voltage rating. It is perfect for applications that need a fast switching of power, and is suitable for AC/DC power supplies. It can also be used in applications with low electro-mechanical stress, and up to a maximum of 2600V.
