Projekt Anglicky v odborných předmětech, CZ.1.07/1.3.09/04.0002 Anglicky v odborných předmětech "Support of teaching technical subjects in English“ Tutorial: Mechanic - electrician Topic: Technical training II. class Transistors 4 Prepared by: Melichařík Lubomír Projekt Anglicky v odborných předmětech, CZ.1.07/1.3.09/04.0002 je spolufinancován Evropským sociálním fondem a státním rozpočtem České republiky.

TRANSISTORS 4 Distribution of transistors according to performance Conventional transistors : - usually process a signal in units of volts. - Current is maximum in the order of milliamps Medium-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.

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 ...)

Distribution 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 power

Conventional transistors-Types the most common cases: TO18 TO39 TO72 TO92 SMD SOT23 SOT 223 SOT 416

medium-performance transistors Types of the most common cases: TO126, TO220
