Build your own low-power transmitters: The BC is a low voltage, low current, general-purpose switching transistor in a TO package. Would I reuse it? No other pin will show that. The maximum amount of current that could flow through the Collector pin is mA, hence darasheet cannot connect loads that consume more than mA using this transistor. Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site the association bonus does not count.

This transistor will make eatasheet forward biased and thus closes the connection between collector and emitter. From Wikipedia, the free encyclopedia. I don’t think so – throw it in the bin.

This transistor like all can be used either as a switch or as an amplifier. Billions of units have been manufactured over the past 45 years and there is continuing high volume annual production.

It looks like a “diode”. The 2N is considered a very common transistor, [1] [2] [3] and is used as an exemplar of an NPN transistor. datssheet

This is the picture of the datasheet for the pins: They’re listed together because they’re complementary transistors. Wikimedia Commons has media related to 2N I have a eatasheet circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA: In actual circuit modifications might be required.

TL — Programmable Reference Voltage. Thank you for your interest in this question. The value for this resistor can be calculated using the formula. Therefore, it is important to refer to the datasheet for the exact part number and manufacturer. Try not to touch the transistor while testing it because temperature will change the voltage readings.

But there are two important features that distinguish both. Archived from the original on 14 April The JEDEC registration of a device number ensures particular rated values will be met by all parts offered under that number. The 2N is an NPN transistor that can only switch one-third the current of the 2N but has otherwise similar characteristics.

It is designed for low to medium currentlow powermedium voltageand can operate at moderately high speeds. The situation worsen when all these china fake transistors crowded the whole market, there are no standardization at all.

I am trying to figure out what is going on here. Hence the 2N pin-out is sadly not standardized.

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. To bias a transistor we have to supply current to base pin, this current Datashset B should be limited to 5mA. When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter.

It is frequently used as a small-signal transistor, [4] [5] and it remains a small general purpose transistor [6] of enduring popularity. To make things simple I have shown a simplified circuit to make a transistor as switch. The hFE is usually much higher when 222a connected than when collector and emitter are swapped.

I have used a base voltage of 5V and a value of 1K as datawheet limiting resistor. How to use 2NA This transistor like all can be used either as a switch or as an amplifier.
