2222a transistor datasheet pdf
The 2N2222AHR is a silicon planar NPN transistor specifically designed and housed in hermetic packages for aerospace and Hi-Rel applications. Transistor BC547 is probably the most elementary of the available electronic active components and yet becomes the basic, vital building block in most electronic circuits. 2N4401 Datasheet, Equivalent, Cross Reference Search The Base-Emitter voltage of this transistor datssheet 6V so you just have to supply this voltage across the base and emitter of the transistor to induce a base current into the transistor. It is frequently used as a small-signal transistor,   and it remains a small general purpose transistor  of enduring popularity.

I tried several 3904s with no luck then I tried a 2222A and it worked fine same with 4401. Datasheet Identification Product Status Definition Advance Information Formative or In Design This datasheet contains the design specifications for product development. Puede amplificar pequeñas corrientes a tensiones pequeñas o medias; por lo tanto, sólo puede tratar potencias bajas (no mayores de medio vatio).Puede trabajar a frecuencias medianamente altas. A voltage or current applied to one pair of the transistor's terminals controls the current through another pair of terminals. 1997 May 294Philips SemiconductorsProduct speciﬁcationNPN switching transistors2N2222; 2N2222ACHARACTERISTICSTj =25 °C unless otherwise speciﬁed.SYMBOLPARAMETER datasheet search, datasheets, Datasheet search site for Electronic Components and Semiconductors, integrated circuits, diodes and other semiconductors. The other two wires from the toroid go to the resistor and to the intersection of the transistor with the LED. The 2N is a common NPN bipolar junction transistor (BJT) used for general purpose depend on the manufacturer, case type, and variation. Make a Simple Ambient Light Sensor/Night Light Paper Circuit: EDIT: We've added a 2nd version of this activity that improves the circuit a bit in terms of function and reliability based on input from the amazing Instructables community (see comments at the end of this Instructable).
The 2N2222 is a common NPN bipolar junction transistor (BJT) used for general purpose low-power amplifying or switching applications. NPN SMALL SIGNAL TRANSISTOR IN SOT23 Features Ideally Suited for Automatic Insertion Complementary PNP Types: BC856 – BC858 For switching and AF Amplifier Applications Totally Lead-Free & Fully RoHS compliant (Notes 1 & 2) Halogen and Antimony Free. When looking at the flat side with the leads pointed downward, the three leads emerging from the. The NPN transistor is made up of two N-type material layers with a layer of sandwiched of P-type. Please consult the most recently issued document before initiating or completing a design.
The general specifications of 2222a 222a2 variants are similar, with the biggest difference being the maximum allowable current and power 2222a. So if you looking for an NPN transistor that could switch loads of higher current then 2NA might the right choice for your project. PINNING PIN DESCRIPTION 1 collector 2 base 3 emitter Fig.1 Simplified outline (TO-92; SOT54) and symbol. 2N2222A has a gain value of 110 to 800, this value determines the amplification capacity of the transistor. A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power.It is composed of semiconductor material usually with at least three terminals for connection to an external circuit.
Sirve tanto para aplicaciones de amplificación como de conmutación.
Typical examples are the well known NPN and PNP industrial and military types, 2N and 2N, which have been used for over four decades and are still being used in many designs.
