Summary

Description
English: KT117 / 2T117 unijunction transistor cut open
Two visible contacts on the crystal are Emitter (the bigger one) and Base-1 (smaller one). Base-2 is the bottom side of crystal.
Nominal B1 to B2 resistance is 4 – 7.5 kΩ for this model, this specimen shows 5.7 kΩ
Русский: КТ117Б / 2Т117Б однопереходный транзистор со снятой крышкой
Два видимых контакта на кристалле - Эмиттер (крупный) и База-1 (меньший). База-2 - это нижняя сторона кристалла.
Номинальное межбазовое сопротивление транзисторов 2Т117Б - от 4 до 7.5 кОм, данный образец имеет сопротивление 5.7 кОм
