Due to this biasing current, 2N3904 goes to the saturation state and the LED turns ON. 2N3904 Datasheet : NPN General-Purpose Amplifier, 2N3904 PDF Download Fairchild Semiconductor, 2N3904 Datasheet PDF, Pinouts, Data Sheet, Equivalent, Schematic, Cross reference, Obsolete, Circuits. When the switch is closed, the base of the transistor is biased, and current flows to the base of the transistor. ![]() Due to this, 2N3904 remains in the cut-off state and the LED does not glow. And no current flows to the base of the transistor. When the switch is open, the base of the transistor is not biased. Is a 2N3904 Model Built Into the PSPICE-TI Download I assume that it is based on this - I click on Place-Part At the bottom, I click on Search for Part and enter 2N3904 Under Libraries, it shows 2N3904/Transistor. ![]() The required resistor value can be easily calculated using Ohm’s law. Proper biasing of the base ensures adequate base current to turn ON the transistor.Ī resistor of 220 Ohm is connected between the load(LED) and the collector terminal to protect the LED from overcurrent. The base of the transistor is biased using a 10 K Ohm resistor(R3) in parallel to the 1 K Ohm resistor(R2) plus base-emitter junction resistance(in series). The complete circuit is powered via a 5 V supply. With a free account on Museo, you can download up to five tracks each day.
