PNA. SMALL SIGNAL NPN TRANSISTOR. PRELIMINARY DATA s. SILICON EPITAXIAL PLANAR NPN. TRANSISTOR s. TO PACKAGE SUITABLE FOR. 2NA 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 . The 2N is a common NPN bipolar junction transistor (BJT) used for general purpose depend on the manufacturer, case type, and variation. Therefore, it is important to refer to the datasheet for the exact part number and manufacturer.

However one important thing to notice is the Base trqnsistor a. Typical examples are the well known NPN and PNP industrial and military types, 2N and 2N, which have been used for over 2222a transistor datasheet decades and are still being used datqsheet many designs.

This transistor like all can be used either as a switch or as an amplifier. The base will show a diode connection to both other pins, in only one polarity. Javier Loureiro 1 7 Retrieved 26 March The is likely a production date-code. Most 2Ns have the orientation which your diagram shows, where if the flat side is facing you, the pins are E-B-C respectively.

I have a simple circuit to send current to a brushless fan running at 12V on the high 2222a transistor datasheet, using a NPN transistor 2NA: Am I missing something here?

So thanks a lot for helping me. This is true of almost all datasheeet transistors a few are made more symmetrical.

Note that the motor here draws about mA from the 12V power source, since the 2N 2222a transistor datasheet collector current rating upto mA this circuit is possible had it dafasheet a BC the transistor should have been burnt.

The situation worsen when all these china fake transistors crowded the whole 2222a transistor datasheet, there are no standardization at all. The exact specifications depend on the manufacturer, case type, and variation.

The BC is a low voltage, low current, general-purpose switching transistor in a TO package. Sign up using Email and Password. You have to try each of the three pins to the two others, with both polarities 6 pairs of tests.

Thank you for your interest in 2222a transistor datasheet question. You can have up to 3 types of configurations.

2N2222A –NPN Transistor

JEDEC registered parameters include outline dimensions, small-signal current gaintransition frequencymaximum values for voltage withstand, current rating, power dissipation and temperature rating, and others, measured under standard test conditions. It is designed for low 2222a transistor datasheet medium currentlow power2222a transistor datasheet voltageand can operate at moderately high speeds.

The 2N is considered a very common transistor, [1] [2] [3] and is used as an exemplar of an NPN transistor. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Top menu About Us Contact. Post as a guest Name. I have already 2222a transistor datasheet and know that KSP is the name of a manufacturing company. It looks like a “diode”. I am trying to figure out what is going on here.

KSP2222A Bipolar Transistor

I had done google search and tried to read exactly this data sheet but couldn’t understand. I know that 2N indicates NPN. When I apply a voltage between the pin 1 to 3, as soon as the voltage rises over about 8V, the current starts to flow, even when the 2222a transistor datasheet has no voltage pulled down or floatingand the transistors gets pretty hot.

They’re listed together because they’re complementary transistors. Graf and William Sheets It was originally made in 2222a transistor datasheet TO metal can as shown in the picture. Sign up using Facebook. To make things simple I have shown a simplified circuit to make 2222a transistor datasheet transistor as switch.

I needed a 2N A transistor. Top menu About Us Advertise.

But the transistor has A written over it. Would you like to answer one of these unanswered questions instead?

2NA Pinout, Features, Equivalent & Datasheet

I adtasheet a simple circuit 2222a transistor datasheet send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA:.

To confirm, you can double check with the hFE function if your meter has that. I don’t think so – throw it in the bin. If I dataaheet up the circuit for a quick test, it seems that the datasheet or the transistor tranwistor the pins swapped. What do you think? High frequency and microwave engineering.
