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. WebWhen BJT’s are used as load switches, they are used in two modes: Cutoff and Saturation. Consider figure 3 below. As previously stated, I C = βI B. So, if I B = 0, then I C must also be 0. In this state, the transistor is in cut-off mode.
