Our information and communications world owes a debt to a team of physicists who took theories that had been kicking around for decades, and - after years of false starts and dead ends - got the first transistor to work early in the postwar era. Just about everything electronic is full of them. You’d be hard-pressed to find a gadget or gizmo within reach that does not contain a transistor.

We’re exploring the cultures of innovation that brought us the device that changed everything. The transistor was born in December of 1947, in New Jersey, and it has defined the last half of the 20th century and the first quarter of the 21st. Odds are, you are surrounded by them right now. If some data source only has data for the active region, this is probably good enough.The future began 75 years ago this week with the invention of something small that’s considered the most manufactured item in human history. 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.To explain further, for a simple BJT circuit we have the following variables.

Is there anywhere I can download some current-voltage data for a bipolar junction transistor? (It doesn't matter that much which one.)
