WebFeb 24, 2012 · A Bipolar Junction Transistor (also known as a BJT or BJT Transistor) is a three-terminal semiconductor device consisting of two p-n junctions which are able to amplify or magnify a signal. It is a current controlled device. The three terminals of the BJT are the base, the collector and the emitter. A BJT is a type of transistor that uses both ...

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. WebTherefore, in order to eliminate this possibility, we use what is known as an “Overdrive Factor” (ODF). This is an arbitrary number between 2 and 10 that is used to insure that the transistor is driven hard into saturation (fully turned on) — and where temperature changes fail to drop the transistor out of saturation. Therefore, IB equals: how to report a tax cheat
