Hi. I feel that I have decent knowledge when it comes to mosfets, but there are a lot of thinks I simply don't know about BJT's. With fets I can find Rds(on), Id leakage, gate capacitance and then calculate the time it takes for the fet to turn on and off, but how does this relate to a BJT? What is the turn on-time, leakage current and resistance of a BJT? This might be the wrong questions to ask, but rather, what is Ic when Ib=0? What is Vce when Ic<Ib*Hfe? I keep wondering if BJT's are better than fets for battery powered operations (if it has lower leakage current) or for high current applications (if it has a lower voltage drop). Can someone please clarify this for me?
