Types of MOSFET 5A

As 5A MOSFETs are named according to their construction and operation, there are various types of 5A MOSFET. Each type has different applications.

These types include:

• Enhancement Mode MOSFETs

  Enhancement Mode MOSFETs are ordinarily OFF. This means that with no gate voltage, channel conduction occurs. Also, for an N-channel enhancement mode MOSFET, positive gate-source voltage is necessary to create an inversion channel. Therefore, these MOSFETs are applied in switching power supplies. This is due to their capability to operate at higher frequencies.

• Depletion Mode MOSFETs

  Unlike Enhancement Mode MOSFETs, Depletion Mode MOSFETs are normally ON. This means that they conduct even without applying gate voltage. However, applying voltage can reduce the channel conductivity. That said, N-channel depletion-mode MOSFET requires negative gate-source voltage. Conversely, P-channel depletion-mode MOSFET requires positive gate-source voltage. These devices are used in signals amplification circuits.

• Low Threshold MOSFETs

  Low Threshold MOSFETs have been designed to turn ON at low gate-source voltages. Normally, standard MOSFETs require high voltages to enhance conduction. However, these 5A MOSFETs are suitable for driving applications with low gate voltages. This includes battery-operated devices. Also, these components provide efficient switching in low-voltage circuits.

• Power MOSFETs

  Power MOSFETs are high current and high voltage devices. They provide efficient switching in power applications. Such applications include power supplies and motor drives. Due to their low on-resistance and high current capacity, these MOSFETs are used in the heavy industries.

• IGBTs (Insulated Gate Bipolar Transistors)

  Igbt combines the benefits of both MOSFETs and bipolar transistors. They provide high efficiency and good switching capabilities. That is why these devices are mostly used in heavy-duty applications. Such applications as power inverters, induction heating, and motor drives.
