Similarly, in the cut-off region, it works as an open switch means both junctions will be reverse biased, and emitter-base voltage will be less than 5V thus transistor works as a fully open switch. In the saturation region, it works as close switch means both junctions will be forward biased, and emitter-base voltage will be greater than 5V thus transistor works as a fully closed switch. In the active region, it works as an amplifier means its emitter-base junction will be forward biased and the collector-base junction will be reversed biased. Either it is used for switching or amplification it works in three modes of operation. Collector emitter saturation voltage: 0.25Vįor further details download datasheet 2N3906 DataSheet Where and How to Use 2N3906 TransistorĢN3906 transistor is generally used for high-speed switching and amplification purpose.Storage temperature range: -55 to 150C 0.Minimum forward current transfer ratio: 100.Junction operating temperature range: -55 to 150C 0.Do not operate load above 40V DC, always use a suitable base resistor, confirm the pin configuration before placing the circuit to place it right, do not store of operate in temperature below -55 centigrade and above +150 centigrade.Emitter pin is input pin used for basing the emitter base junctionīase pin is control pin used for controlling the emitter to collector current.Ĭollector pin is output pin used for providing current to the load. To get good and long term performance with this transistor it is suggested to not operate load more than 200mA. How to Get Long Term Performance with 2N3906 The emitter-base voltage of the transistor is 5V due to which it can also be used at the output of microcontrollers. On the other hand if you want to use it as a switch then you can drive any load under 200mA with this transistor for example Relays, LEDs, high power transistors etc. Moreover it can be used to amplify any type of small signal. Features: PNP Silicon Planar Switching Transistor General Purpose Switching and Amplifier Applications Absolute Maximum Ratings Thermal Resistance Electrical Characteristics (Ta 25☌ unless otherwise specified) Small Signal Characteristic Switching Time Pulse Condition : Pulse Width 300s, Duty Cycle 2. It can also be used as an audio preamplifier or in any other audio related circuit. Moreover the max collector dissipation value, DC current gain value also makes it ideal to use in wide variety of simple audio frequency applications.ĢN3906 can be used in many projects for example it can be used in audio amplifier circuits for general or small amplification requirements. The max collector current of the transistor is 200mA therefore it can be used to drive any load which falls under 200mA or 0.2A. The transistor is manufactured to perform general purpose tasks in electronic circuits hence it can be used for any general purpose requirement in electronic circuits that fall in its max specification values.
