  1. Anglicky v odborných předmětech"Support of teaching technical subjects in English“ Tutorial: Mechanic - electrician Topic: Technicaltraining 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.

  2. 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.

  3. 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 ...)

  4. TRANSISTORS 4 • 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

  5. TRANSISTORS 4 • Conventional transistors-Types the most common cases: TO18 TO39 TO72 TO92 • SMD SOT23 SOT 223 • SOT 416

  6. TRANSISTORS 4 • medium-performance transistors • Types of the most common cases: • TO126, TO220

  7. TRANSISTORS 4 • Power transistors Types of the most common cases: • SOT93, SOT 429(TO247) TO218, • TO3P, TO3

  8. Activities for students – mandatory slideTask, test, questions … . • 1. Divide the transistors into three basic categories according to performance. • 2. Where are transistors according to performance used?

  9. Activities for students – mandatory slideTask, test, questions … . Two slides are best. • 1. Please list at least 3 types of conventional transistors. • 2. Please list at least 3 types of medium-power transistors. • 3. Please list at least 3 types of power transistors. • 4. Draw three basic types of transistors cases.
