It can also be used in the various switching applications.ĢD dimensions will help you in placing this component at the time of making circuit on perf board or a PCB.Some of the text files within the PDF file.Can be used to switch high current (upto 800mA) loads.Note that the motor here draws about 500mA from the 12V power source, since the 2N2222 has collector current rating upto 800mA this circuit is possible had it been a BC547 the transistor should have been burnt.
Elcot tv circuit diagram The LA76931 COLOUR TV CHROMA IC DATA SHEET AND. I have used a base voltage of 5V and a value of 1K as current limiting resistor. minta tolong dengan Samsung slim 21 UOC TDA12156 - transistor HOT TT2222. In actual circuit modifications might be required. To make things simple, I have shown a simplified circuit to make a transistor as switch. The value for this resistor can be calculated using the formula As the name suggests this resistor will limit the current flowing through the transistor to prevent it from damaging. However one important thing to notice is the Base resistor a.k.a current limiting resistor. TT2222 datasheet pdf, TT2222 datasheets pdf, TT2222, TT2222. This transistor will make it forward biased and thus closes the connection between collector and emitter. The Base-Emitter voltage of this transistor is 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. This transistor like all can be used either as a switch or as an amplifier. So if you looking for an NPN transistor that could switch loads of higher current, then 2N2222A might the right choice for your project. 2N2222A can allow collector current upto 800mA and also has power dissipation of 652mW which can be used to drive larger loads than compared with BC547. But there are two important features that distinguish both. The 2N2222A transistor is very much similar to the commonly used NPN transistor BC547. 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. 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. 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. 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. 2N2222A has a gain value of 110 to 800, this value determines the amplification capacity of the transistor.
