![]() ![]() 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. 2N2222 is the best transistor for switching loads of higher currents. I am interested in writing some simulations involving BJTs which requires more information than can be obtained from the typical transistor equations. The 2N2222 and BC549 transistors Because the amplifier wiring diagram in the previous paragraph does not take into account the component’s beta value, it can be used with any type of transistors (see Figure 2), and thus, any device with any amplification factor (Hfe) will operate correctly. It uses a 10ns delay time, 225ms storage time, 60ms fall time, and 25ms rise time to operate on a high transition frequency of 250MHz. 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? The 2N2222 transistor provides a constant DC collector current of 800mA, making it ideal for applications requiring low to medium current. 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. Diode 1N4007 vvvvvvvv Included SPICE model from 1N4007.mod vvvvvvvv. Click for a tutorial example and gschem with opamp.Also google spice and go to links like this. ![]() Is there anywhere I can download some current-voltage data for a bipolar junction transistor? (It doesn't matter that much which one.) Spice Stuff: diode and transistor models netlist examples for feedback amplifier, reverse recovery time of diode, and opamp amplifier. ![]()
