释义 | transistor[ tran-zis-ter ] / trænˈzɪs tər / SEE SYNONYMS FOR transistor ON THESAURUS.COM nounElectronics. a semiconductor device that amplifies, oscillates, or switches the flow of current between two terminals by varying the current or voltage between one of the terminals and a third: although much smaller in size than a vacuum tube, it performs similar functions without requiring current to heat a cathode. Informal. a transistorized radio. adjectiveInformal. transistorized: a transistor radio. Origin of transistorFirst recorded in 1945–50; trans(fer) + (res)istor Words nearby transistortransient modulation, transient synovitis, transignification, transilient, transilluminate, transistor, transistorize, transit, transitable, transit camp, transit circle Dictionary.com UnabridgedBased on the Random House Unabridged Dictionary, © Random House, Inc. 2020 Example sentences from the Web for transistorBritish Dictionary definitions for transistortransistor / (trænˈzɪstə) / nouna semiconductor device, having three or more terminals attached to electrode regions, in which current flowing between two electrodes is controlled by a voltage or current applied to one or more specified electrodes. The device is capable of amplification, etc, and has replaced the valve in most circuits since it is much smaller, more robust, and works at a much lower voltageSee also junction transistor, field-effect transistor informal a transistor radio Word Origin for transistorC20: originally a trademark, from transfer + resistor, referring to the transfer of electric signals across a resistor Collins English Dictionary - Complete & Unabridged 2012 Digital Edition © William Collins Sons & Co.

It is normally made from silicon or other semiconductors. notes for transistorThe transistor is the basic device used in miniaturized electronic systems, such as portable radios, or as a fast switch in computers.

Transistors usually consist of three layers of semiconductor material, in which the flow of electric current across the outer layer is regulated by the voltage or current applied at the middle layer. Having replaced the vacuum tube, transistors are the basis of much modern electronic technology, including the microprocessor. See also logic circuit logic gate.
