The KT315 is a Soviet NPN bipolar junction transistor used for general purpose low-power amplifying or switching applications, performed in the plastic KT-13 case. It has been widely used in the Soviet electronic equipment. A KT361 is a complementary (PNP) for the KT315 transistor, so it often used with it in a pair in push-pull circuits. KT315 and KT361 transistors became the first in the USSR, which were produced by planar technology. Ratio of the parameters reached in the KT315 was a breakthrough at that time. Such process of manufacturing was much cheaper than floatable technology, and allowed to receive inconceivable earlier transistor parametres, in particular, working frequency of 250-300 MHz.〔(【引用サイトリンク】url=http://sysmagazine.com/posts/179265/ )〕 The development of KT315 was awarded with the USSR State Prize in 1973.〔(【引用サイトリンク】script-title=ru:Музей электронных раритетов - Актив - КТ315+КТ361 )〕 == Application == KT315 transistors were designed for use in amplifier circuits of high, medium and sound frequencies. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「KT315」の詳細全文を読む スポンサード リンク
