What is a single-junction transistor? What special features does it have? Also known as single-junction transistor double base diode, is a semiconductor device (Fig. 6) by a PN junction and three electrode composition. Let's draw a diagram of its structure [Figure 7 (a)]. At both ends of a N-type silicon SCR BTA312, making the two electrodes SCR BTA216, are called first base and second base B1 B2; B2 near the other side of the silicon produced at a PN junction equivalent to a diode, the P region called the emitter electrode leads E. In order to facilitate analysis of SCR BTA208, can put N-type region B1, B2 between a pure resistance equivalent to how to use the single-junction transistor SCR trigger circuit? We draw a separate single-junction transistor relaxation oscillator circuit (Figure 8). It consists of a single-junction transistor and RC charge-discharge circuit composed. After closing the switch S, the power UBB via potentiometer RP to charge the capacitor C, the voltage on the capacitor UC rise exponentially. When UC rises to single-junction transistor UP when the peak voltage, single-junction transistor suddenly turned SCR BTA212 | SCR | are fertile Electronics Dongguan City is provided by Wal-Electronic Technology Co., Ltd.
