Transistors Transistor - NPN, 50V 800mA (BC337) images are CC BY 2.0 Share Previous Versions Transistor - NPN, 50V 800mA (BC337) COM-13689 RoHS 0. The company was founded in 2006 and is headquartered in Eindhoven, Netherlands. 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.NXP Semiconductors is a publicly traded multinational company that designs, develops, and manufactures a wide range of semiconductors and integrated circuits for various applications, including automotive, industrial, communications, and consumer markets.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. I have used a base voltage of 5V and a value of 1K as current limiting resistor. 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. 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. You can chose another available transistor. In this example the motor is a little motor and just for this the 2N2222 its enough for this use, while the 1N4007 is much more than enough. the 2N2222 is a general purpose good transistor and the 1N4007 is an honest rectifier, hard to die. 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. There is not a thin range where chose the components. 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. 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. 2N2222 30V,800mA,400mW Through-Hole Transistor-Small Signal (<1A) NPN High Current :: Part, Case and Package Specifications, Availability and Datasheets. 2N2222A has a gain value of 110 to 800, this value determines the amplification capacity of the transistor. Note: Complete Technical Details can be found at the 2N2222A datasheet given at the end of this page. Collector Emitter Voltage (V CE) is 30V.Continuous Collector current (I C) is 800mA.
