Assuming a minimum value of 2V and a transistor ON voltage of 1V gives an LED/transistor current is (5-3) / 330Ω = 6mA. When the transistor starts to turn on depends upon its gain. From the data sheet the 2N3904 has a gain that varies from 100 to 300 at 10mA with a collector emitter voltage of 1V. 2N3904 Electrical Characteristic Curves Fig. 2 hFE-IC Fig. 3 VCE(sat)-IC Fig. 1 PC-Ta

The 2N3904 is a common NPN bipolar junction transistor used for general-purpose low-power amplifying or switching applications. It is designed for low current and power, medium voltage, and can operate at moderately high speeds. The 2N3904 comes in a TO-92 case with leads in the order C,B,E. Some equivalent transistors have the opposite pinout (E,B,C) and some are B,C,E. This won't be a problem so long as you are aware of the difference, and refer to the datasheet of the part you are using when wiring up the circuit. This is the Transistor Prototype PCB Design Kit with 2N3904 & 2N3906 Transistors.This kit is what you need to develop numerous different transistor circuits. It includes the extremely useful NightFire Prototype Transistor PCB along with some of the very popular 2N3904 NPN & 2N3906 PNP Transistors in the standard leaded TO-92 package.

How to Measure the Small Signal Characteristics of a BJT: A bipolar junction transistor, or BJT, is a type of transistor. They are commonly found in electronic amplifier circuits such as those used to transmit data wirelessly, and in radios.The above image is a schematic of a BJT. R3 is needed to start the regulator. Without R3 there wouldn’t be a voltage at the output and hence there wouldn’t be a base current in T2. R3 lets T2 conduct a little bit, which is sufficient for the regulator to reach its intended state. 2N3904 fT 250 300 − − MHz Output Capacitance (VCB = 5.0 Vdc, IE = 0, f = 1.0 MHz) Cobo − 4.0 pF Input Capacitance (VEB = 0.5 Vdc, IC = 0, f = 1.0 MHz) Cibo − 8.0 pF Input Impedance (IC = 1.0 mAdc, VCE = 10 Vdc, f = 1.0 kHz) 2N3903 2N3904 hie 1.0 1.0 8.0 10 k Voltage Feedback Ratio (IC = 1.0 mAdc, VCE = 10 Vdc, f = 1.0 kHz) 2N3903 2N3904 hre 0.1 0.5 5.0 8.0 X 10−4 2N3904 General Purpose Transistors NPN TO-92 Page 1 31/05/05 V1.0 High Speed Switching Features: • NPN Silicon Planar Switching Transistors. • Fast switching devices exhibiting short turn-off and low saturation voltage characteristics.

Sep 15, 2019 · Here is an Inverting Amplifier. It’s more convenient when to use a single power supply, 4V to 15V. Because both resistors R3, R4 connect together in voltage divider form. And Capacitors coupling an audio signal. MIC1 gets any sounds to convert to an audio signal. C1 passes that signal through R2 to non-inverting input pin 3. Parts List:R1,R3 = 10K Q1 = 2N3904, or equivalent R2 = 680K (see text)IC1 = 4001, or equivalentR4,R5 = 6K8 D1,D2,D3 = 1N4001, or equivalent C1 = see textRy = Relay, 12V C2 = 0.1uF, ceramic I can get the circuit to work by connecting the emitter side of the 2n3904 to the ground of the Arduino and the collector side to the IN1 of the Relay.
