power transistor?

Question

I wnat to know re. power tarnsistors,its types and characteristics.

Answer 1

Power transistors are more or less like rugged BJT transistors. They are controlled by a base current and can usually withstand a relatively large amount of collector-to-emitter current.

A close relative to the power transistor is the IGBT (insulated-gate bipolar transistor). It is basically the power electronics equivalent of a MOSFET, since it has an insulated gate that is controlled by a voltage rather than a current.

Both of these transistor types are used commonly in high power switching applications such as motor drives or power supplies.

Answer 2

1.Power transistors are transistors that are used in high-power amplifiers and power supplies.
2.Power transistors are suited for applications where a lot of power is being used- current and voltage.
3.The collector of the transistor is connected to a metal base that acts as a heat sink to dissipate excess power.
4.Typical power ratings range from around 10 to 300 W, with frequency ratings from about 1 to 100 MHz. 5.Maximum Ic values range between 1 to 100 A.
6.Power transistors come in npn, pnp, and Darlington (npn or pnp) forms.

Answer 3

One capable of being used at power rating of greater than about 10 watts, and generally requiring some means of cooling

Answer 4

If you know the type or mfg. number of the transistor, you can look up the specs. at this link.

Answer 5

which one. there are many types and you can specify what characteristics you need, look it up in parts suppliers for electronics or a devices manual, good luck
