Advantages and disadvantages of power transistor

Advantages:

There are some advantages of power transistor which are given below,

• The power transistor can be operated at switching frequencies in the range of 10 to 15 kHz.
• The power transistor can carry large currents in ON state and block very high voltage in OFF state.
• It is very easy to turn ON and turn OFF the power transistor.
• The ON state voltage drop across power transistor is low.
• It can be used to control power delivered to the load, inverters and choppers.

Disadvantages:

There are some disadvantages of power transistor which are given below,

• Reverse blocking capacity is very low in the power transistor.
• The power transistor cannot be operating satisfactorily above switching frequency of 15 kHz.
• It can be damaged due to thermal runway or second breakdown.
