Conventional transistors :- usually process a signal in units of volts. - Current is maximum in the order of milliampsMedium-performance transistors:- work mostly in the linear regime, for example, they are used for linear voltage regulators, or for power levels for audio amplifiers.Power transistors :- in a switching mode it works with a voltage (tens of kilovolts) and currents of hundreds or thousands of amperes.TRANSISTORS 4

Distribution of transistors according to performance

Conventional transistors are used:- for signal processing as individual "discrete" components- parts in chips and microchip integrated circuits, are today an essential element of the consuming and non-consuming electronics (televisions, radios, computers, mobile phones ...)TRANSISTORS 43Distribution of transistors according to performance

Power transistors are used: are a key element used in power electronics, (switching power supplies or frequency converters.) ---- modern light sources- hybrid cars and electric vehicles- photovoltaic and wind powerTRANSISTORS 4
