No matter how much current you drive into the base, the transistor voltage from collector to emitter can only go as low as 0V. This means the collector current depends on ...

Web31. When choosing the right transistor for this job, first I'll eliminate the PNP transistors. They're a bit more complicated to use in your case. As you said, for a PNP transistor, active high becomes active low, meaning the transistor will switch on when you apply 0V from your Arduino, but it won't switch off when you apply 5V from the Arduino. Web7 de jan. de 2016 · Storage time (ts) - how long to get out of saturation. Using the datasheet (these parameters are usually listed), you can figure out how fast a transistor can switch between the two states. f m a x = 1 t d + t r + t f + t s. * This is what transistor can theoretically do, but there are tricks that can be done to improve the switching speed.

WebTransistors can be regarded as a type of switch, as can many electronic components.
