The 2n22a lower of the two voltages will correspond to the collector-base junctionand the other will be the emitter-base junction. Would you like to answer one of these unanswered questions instead?

Would I reuse it? But there are two important features that distinguish both. It is frequently used as a small-signal datasheeh, [4] [5] and it remains a small general purpose transistor daasheet of enduring popularity. I don’t think so – throw it in the bin.

Archived from the original on 14 April The maximum amount of current that could flow through the Collector pin is mA, hence we cannot connect loads that consume more than mA using this transistor. This is true of almost dqtasheet modern transistors a few are made more symmetrical. The 2N, 2N, and 2N devices, for example, which date back to the s but have been improved, are still useful in new designs and are still popular for experimenters.

Zuofu 3, 2 15 To distinguish collector from emitter, you look at the voltage shown in the diode function with the one successful test that found the base. As the name suggests this resistor will limit the current flowing through the transistor to prevent it from damaging.

Try not to touch the transistor while testing it because temperature will change the voltage readings. This datasheey the pic of the transistor, as I understand that it should work, but it doesn’t it is always ‘on’ with 12V between the collector and the emitter with the base floating.

Retrieved 26 March The 2N is an NPN transistor that can only switch one-third the current of the 2N but has otherwise similar characteristics. The situation worsen when all these china fake transistors crowded the datasheey market, there are no standardization at all. I am trying to figure out what is going on here.

High catasheet and microwave engineering. Absolute maximum rating for emitter-base voltage is 6V hence the E-B junction broke down and started conducting.

However one important thing to notice is the Base resistor a. In actual circuit modifications might be required.

It can be even worse, since the On Semi PN has the conventional pinout, despite being the same manufacturer and mostly same specifications: 2n222z was originally made in the TO metal can as shown in the picture.

Other part numbers will have different parameters.

Therefore, it is important to refer to the datasheet for the exact part number and manufacturer. Am I missing something here? By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

From Wikipedia, the free encyclopedia. To confirm, you can double check with the hFE function if your meter has that. Thank you for your interest in this question. You can have up to 3 types of configurations. The BC is a low voltage, low current, general-purpose switching transistor in a TO package. Wikimedia Commons has media related to 2N The base will show a diode connection to both other pins, in only one polarity.

So if you looking for an NPN transistor that could switch loads of higher current then 2NA might the right choice for your project. Use dmy dates from July Commons category link is on Wikidata. All variations have a beta or current gain h fe of at least in optimal conditions.
