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. high hindi web series
