WebApr 7, 2024 · It is known that a BJT transistor looks like two diodes back to back (or head to head). With this in mind, theoretically we should be able to build a full bridge rectifier … WebMay 22, 2024 · The BJT acts as a switch, completing the circuit between the DC supply, the LED and the current limiting resistor, R C. For this to work reliably, we have to make sure that the ratio of saturation current to base current is much less than β. A value of 10 or so would guarantee hard saturation.
WebSilicon-Controlled Rectifier. The SCR is a three-terminal thyristor that acts like a silicon rectifier diode whose conductor is controlled by an input current. The schematic symbol for an SCR is shown in Fig. 12.21. The symbol is similar to that of a diode with a cathode and an anode. Note that the third element of the SCR is known as the gate.
