![]() The max collector emitter voltage of the transistor is 40V, therefore the user can use it in any circuit operating under 40V DC. The max collector dissipation of the transistor is 625mW which makes this transistor ideal to use it in audio amplifier stages and as an output amplifier to drive small audio speaker. The MMBT2222A is the SMD (SOT-23) version of the popular 2N2222A Transistor. Importantly, its uses are for analog frequency amplification and switching applications. For example the collector current of the transistor is 600mA that is quite good to use it as a switch to drive many loads at a time in an electronic circuit. Description: This device is for use as a medium power amplifier and switch requiring collector currents up to 500mA. 2n2222 is an NPN bipolar junction transistor. The transistor contains some of the best feature in. ![]() DESCRIPTION NPN switching transistor in a SOT23 plastic package. 2N2222 is one of the widely used transistor in commercial appliances, educational and hobby projects. It can be used for amplifying Dasduinos current. Material of transistor: Si Polarity: NPN Total Devise power dissipation PD: 0.5 W(at. 2N2222 is the most basic NPN transistor that you can find and it can be found in our Dasduino Beginner Kit. APPLICATIONS Switching and linear amplification. Package: TO18, 1-emitter, 2-base, 3-collector. But there are two important features that distinguish both. NPN switching transistor MMBT2222A FEATURES High current (max. The transistor contains some of the best feature in its little package. The 2N2222A transistor is very much similar to the commonly used NPN transistor BC547. We also carry BC108C and BC109C so mix and match.ĢN2222 is also one of the widely used transistor in commercial appliances, educational and hobby projects. For instance, this analog frequency could be a human voice. This NPN silicon planar switching transistor is. The 2n2222 transistor amplifies signals by receiving an analog signal through the collectors, and the base gets another signal. The 2N2222 from Multicomp Pro is a through hole, low power bipolar transistor in TO-18 metal can package. All are (new) unused condition and are perfect for all BC108 andBC19 Fuzz projects as well as our American Fuzz, D.S.O.T.M., Muff’n or Sriracha Fuzz style builds Typical hFE is 100-300 so these will work nice in a lower gain early 70’s Muff style build. 2n2222 is an NPN bipolar junction transistor. When base current is removed the transistor becomes fully off, this stage is called as the Cut-off Region and the Base Emitter voltage could be around 660 mV.Description 2N2222 – CDIL. This stage is called Saturation Region and the typical voltage allowed across the Collector-Emitter (V CE ) or Base-Emitter (V BE ) could be 200 and 900 mV respectively. It is used for general purpose low-power amplification and switching applications. When this transistor is fully biased then it can allow a maximum of 800mA to flow across the collector and emitter. To bias a transistor we have to supply current to base pin, this current (I B ) should be limited to 5mA. Ive been experimenting with a 2N2222 transistor (in the TO-18 metal case) and using it as an avalanche transistor - by not connecting the base and having the emitter and collector connected in reverse (so maybe Im actually using the reverse mode, Im not really sure). The maximum amount of current that could flow through the Collector pin is 800mA, hence we cannot connect loads that consume more than 800mA using this transistor. ![]() ![]() It was designed to work with TO-18 metal cans, as illustrated in the diagram. Its made to run at moderate speeds with low to medium current, low power, and medium voltage. 2N2222A has a gain value of 110 to 800, this value determines the amplification capacity of the transistor. The 2N2222 is a typical NPN bipolar junction transistor (BJT) that is used for l ow-power amplification and switching. 2N2222A is a NPN transistor hence the collector and emitter will be left open (Reverse biased) when the base pin is held at ground and will be closed (Forward biased) when a signal is provided to base pin. ![]()
