In this condition, the base is directly connected to the ground. Emitter & Collector Identification Set the Multimeter in diode test mode. 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. A voltage or current applied to one pair of the transistors terminals controls the current through another pair of terminals. 1 It is composed of semiconductor material, usually with at least three terminals for connection to an electronic circuit. 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. The transistor is one of the basic building blocks of modern electronics. Either it is used for switching or amplification it works in three modes of operation. #Transistor emitter collector base how to#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.But, did you know what makes them different from each other Well, each has. It consists of three pins emitter, base, and collector and these pins are used for a different configuration. Storage temperature range: -55 to 150C 0 We all know that a transistor has three terminals- Emitter, Base, and Collector. 2N3906 is a PNP (positive negative-positive) transistor therefore current flows from emitter to collector.The three types of configurations are Common Base, Common Emitter and Common Collector configurations. Using these 3 terminals the transistor can be connected in a circuit with one terminal common to both input and output in a 3 different possible configurations. In theory, at this point the collector/emitter voltage drop (VCE(sat)) should be zero if. Minimum forward current transfer ratio: 100 Let me try to rephrase to see if I understood: BVCEO is the collector-emitter voltage that is enough to forward bias the base, making the transistor to. A Transistor has 3 terminals, the emitter, the base and the collector. In turn, when the transistor is turned off (no base current).Junction operating temperature range: -55 to 150C 0.Figure 1 2N3906 Pinout configuration PinsĮmitter 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.
