What are Power Transistors?

Power Transistors

Power transistors are transistors that are used in high-power amplifiers and power supplies.

Power transistors are suited for applications where a lot of power is being used- current and voltage.

The collector of the transistor is connected to a metal base that acts as a heat sink to dissipate excess power.

Typical power ratings range from around 10 to 300 W, with frequency ratings from about 1 to 100 MHz. Maximum Ic values range between 1 to 100 A.

Power transistors come in npn, pnp, and Darlington (npn or pnp) forms.
