AOK30B135D2 is a transistor of single IGBTs. This device is widely used in multiple application fields, due to its versatile properties. Here in this article, we’ll look into the application fields and working principle of this device in detail.

Application Field

Being a single IGBT, the AOK30B135D2 is chiefly used in motor drives and power controllers. It is a high power semiconductor device used to control or modulate low or medium frequency electrical power, irrespective of the signal magnitude. The device works well even in extreme temperature conditions and is capable of working over a long period of time. It is also used in a variety of other scenarios, such as electric welding, rectifiers, switch-mode power supplies, and in voltage control circuits.

Working principle

In the simplest of terms, an IGBT is basically a field-effect transistor that combines the best features of both bipolar and field-effect transistors. The device works on the principle of “charge-carrier injection”, whereby electrons and holes are injected into semiconductor material in order to form an n-type or p-type region. As a result, electric current is able to flow freely in either direction, depending on the direction of the bias voltage applied to the gate.

The AOK30B135D2 is using the same principle. It is built using an n-type and p-type emitter-base junction, which is injected with charge carriers in order to conduct current. The p-type layer is known as the “gate” and the n-type layer is known as the “collector”. The amount of current that flows from the collector to the emitter is controlled by the voltage applied to the gate. If the voltage is zero, no current flows from the collector to the emitter.

The IGBT also has a forward body diode, which allows the device to conduct current in the forward direction. This enables it to be used for applications such as electric welding and voltage control circuits.

Conclusion

The AOK30B135D2 is a single IGBT device that is used in a variety of application fields, such as motor drives, power controllers, electric welding and rectifiers. It works on the principle of “charge-carrier injection” and has a forward body diode that allows it to conduct currents in the forward direction.
