What is the difference between 2N3904 and 2N2222?
2N3904 can handle up to 200mA (milliamperes) of current flowing from the emitter to the collector terminal. A 2N2222 can handle up to 5 times that amount of current, as it can handle up to 1A (amps) of current flow from emitter to collector to power a load.
How much voltage can a 2N2222A transistor handle?
The transistor 2N2222 or 2N2222A are NPN types and has the following electrical parameters: The device’s maximum voltage tolerance (breakdown voltage) across its collector and base is 60 volts for 2N2222 and 75 volts for 2N2222A, with the emitters kept open.
Which transistor is best for amplifier?
Best Transistors: BJTs
- #1 NPN – 2N3904. You can find most often NPN Transistors in low-side switch circuits.
- #2 PNP – 2N3906. For high-side switch circuits, you need a PNP style BJT.
- #3 Power – TIP120.
- #4 N-Channel (Logic Level) – FQP30N06L.
How do you connect a transistor to a circuit?
To connect the transistor as a switch in a circuit, we connect the output of the device that will switch on the transistor to the base of the transistor. The emitter will connect to ground of the circuit. And the collector will connect to the load that the transistor will turn on and the supply voltage of the circuit.
How much current can a 2N2222 handle?
A 2N2222 can handle up to 5 times that amount of current, as it can handle up to 1A (amps) of current flow from emitter to collector to power a load.
Can I use 2N2222 instead of 2N3904?
The 2N3904 or 2N2222 will suffice if you require less than 200mA. The 2N2222 is the one to choose if you require more than 200mA but not more than 1A. For most circuits, a 2N3904 would suffice, however, if you need more above 200mA, a 2N2222 should be used instead.
Which transistor is mostly used?
There are many types of transistors, but the most commonly used transistors are Field-Effect Transistors and Bipolar Junction Transistors.
What are the 3 connections of a transistor?
A transistor is an electronic device that contains three terminals named emitter, base, and collector.
What are the three connection of transistor?
A Transistor has 3 terminals, the emitter, the base and the collector. Using these 3 terminals the transistor can be connected in a circuit with one terminal common to both input and output in a 3 different possible configurations.
Which transistor is best?
Why NPN is mostly used?
The majority charge carriers in an NPN transistor are electrons and the majority carriers in a PNP transistor are holes. The electrons have better mobility than holes. Therefore, NPN transistors are preferred over PNP transistors. Was this answer helpful?
What are the 2 types of transistor?
Transistors typically fall into two main types depending on their construction. These two types are bipolar junction transistors (BJT) and Field Effect Transistors (FET).
How do you identify a transistor terminal?
In plastic casing, one side of the transistor is Flat which is the front side and the pins are arranged serially. To identify the pins, keep the front flat side facing you and count the pins as one, two etc. In most NPN transistors it will be 1 (Collector), 2 (Base) and 3 ( Emitter ). Thus CBE.
What is meant by Q Point?
The operating point of a device, also known as a bias point, quiescent point or Q-point, is the steady-state DC voltage or current at a specified terminal of an active device such as a transistor with no input signal applied.
How do you select a transistor?
Here are some of the key characteristics of transistors which you must understand before buying a transistor for your upcoming project.
- Collector Current.
- Saturation Voltage.
- Breakdown Voltages.
- Current Gain.
- Material.
- Polarity.
Should I use NPN or PNP?
NPN is a common configuration. Almost all open collector outputs are NPN outputs. The benefit of using a PNP is that the load only connects to the source when it is switched on. In contrast, one side of the load is always connected to the source when an NPN switches it on and off.
How do you test a transistor?
Hook the positive lead from the multimeter to the to the EMITTER (E) of the transistor. Hook the negative meter lead to the BASE (B) of the transistor. For an good NPN transistor, you should see “OL” (Over Limit). If you are testing PNP transistor, the meter should show a voltage drop between 0.45V and 0.9V.
How do you identify a transistor?
To help identify them, transistors are labeled with number and letters on their casings. Transistors are labeled according to the numbering system that is used. The primary numbering systems are JIS, Pro Electron, and JEDEC.
Which pin is which on a transistor?
The pin configuration is the same as that of a Bipolar Junction Transistor. Usually, the device is held such that the flat side is facing toward the person. The pins are numbered from 1 to 3 starting from left to right. Pin 1 is the anode, Pin 2 is the Gate and Pin 3 is the cathode.
