WebLet's say you're given a circuit diagram as follows: I want to find R1 and R2 so that forward voltage drop across the LED is 2V with an overdrive factor of at least 2. Current of 25mA from a source which outputs 0 or 5V through an output resistance of 610 is given. Beta ranges from 50 - 300 So here's my approach. WebWhen the BJT is on, current flows around this loop from collector to emitter. When the BJT is off no current flows through this loop. In this loop, the loop through Vin, through RB, and …

WebDec 6, 2024 · So if you happen to select a nicely-high HFE PN2222A transistor (like HFE=200) then you only need to supply 0.1mA base current to saturate it when driving a 10mA collector or emitter load current. For such a transistor, the rule-of-thumb overdrive factor-of-10 is overkill. But woe be to you if HFE is lower, or temperature drops to -55C.
