If some data source only has data for the active region, this is probably good enough. In other words, all of the non-linearities are important, and the behaviour in regions outside of as well as including the active region are also important. I am interested in writing some simulations involving BJTs which requires more information than can be obtained from the typical transistor equations. Some might become dependent on each other if a complete circuit is drawn including an impedance on the base and collector (or emitter) nodes.Īre there any example devices which have (presumably large) tables of data available for download for measurements of these parameters? ![]() I don't know if these are all independent - I believe they all are. Transistor temperature, which other variables such as the Collector-Emitter current, might have a second order effect from.Transistor HFE (beta) which is a function of temperature.In a PNP transistor, the type of the layers are reversed. An NPN transistor has a piece of P-type silicon (the base) sandwiched between two pieces of N-type (the collector and emitter). Depending on what is added to the silicon, it will be either N-type or P-type. To explain further, for a simple BJT circuit we have the following variables. A bipolar junction transistor is made up of three pieces of silicon. Is there anywhere I can download some current-voltage data for a bipolar junction transistor? (It doesn't matter that much which one.)
