transitronn.

Brit.

/ˈtranzɪtrɒn/,

/ˈtrɑːnzɪtrɒn/,

/ˈtransɪtrɒn/,

/ˈtrɑːnsɪtrɒn/, U.S.

/ˈtrænzəˌtrɑn/

Origin: Formed within English, by derivation. Etymons: transconductance n., -i- connective, -tron suffix.

Etymology: < trans- (in transconductance n.) + -i- connective + -tron suffix.

Electronics. Now rare and chiefly historical.

Any device employing a thermionic valve in which a retarding field is used to cause a fall in current through one electrode as the voltage at a second increases; spec. an oscillator employing a pentode in which the screen grid is coupled to the suppressor grid, providing the former with negative resistance (more fully transitron oscillator).
