Note that the 2N3904 is not the only survivor of those early days. Others include its PNP complement, the 2N3906 and the 2N2222, to cite just a few of these dinosaurs that are still listed as active ...

It is built around transistor 2N2222 (T1), two electrolytic capacitors: one of 10μF, 16V rating (C1) and the other of 4.7μF, 16V rating (C2), two resistors: one of 330 ohm (R1) and the other of ...

This model is applied to simulate the collector of the 2N2222 n-p-n silicon (Si) bipolar transistor under pulse-neutron irradiation. We found that the decrease in electron density under irradiation ...

5. The NPN transistor always has an arrow pointing out. 6. Popular transistors including (from left to right, top to bottom) NPNs 2N2222, 2N3904, and TIPS120 and PNPs 2N3904, and 2N3906.

The code will only turn on the lights if the voltage measured at A1 is below the threshold. Four 2N2222 NPN transistors will power the lights without all of the amperage running through the Arduino.

It’s worth noting that the simulator includes the 2N2222 transistor model; however, the BC549 transistor model must be found elsewhere as a SPICE model. The system includes a 5-V power supply and a ...

Warning! ESD damage risk! The first unit (a simple electroscope) uses a cascade of 2N2222 NPN bipolar transistors configured to give a high current gain, so any charge near the antenna will result ...
