NPN Transistor Tutorial - The Bipolar NPN Transistor

• The current in a bipolar NPN transistor is the ratio of these two currents ( Ic/Ib ), called the DC Current Gain of the device and is given the symbol of hfe or nowadays Beta, ( β )
• Every transistor has its own unique hFE. The hFE is normally seen to be a constant value, normally around 10 to 500, but it may change slightly with temperature and with changes in collector-to-emitter voltage. Check the transistor's datasheet for the hFE value in its specifications. Note that hFE may refer to DC or AC current gain
• The preset collector currents may not be exactly spot on due to resistor tolerances (+/-5%) but they will remain virtually unchanged (within about 1%) for DUT gain variations between 25 and 200. To calculate the hFEfor any collector current (Ic), use the simple formula hFE= Ic / Ib (where Ib is base current
• Both PNP and NPN transistors can be checked using this circuit. Hfe as high as 1000 can be measured by using this circuit.The circuit is based on two constant current sources build around transistors Q1 and Q2.The Q1 is a PNP transistor and the constant current flows in the emitter lead
• Uppbyggnad. Symbol för bipolär NPN-transistor. Symbol för bipolär PNP-transistor. Transistorn är uppbyggd av tre områden, emittern ( E, även markerad med pil ), kollektorn ( C) och basen ( B ). NPN och PNP. Bipolära transistorer kan förekomma i två polariteter, som kallas NPN och PNP. Bokstaven N står för N-dopat och P står för P-dopat material

\$\begingroup\$ Since you have not provided values for the resistors, I cannot give you an example. But if you take hFE = 100 and solve, you will obtain Ic and Vce. Then you can go to the graph and observe if for that Ic and Vce, hFE = 100 is a valid assumption. hFE has a big variance, that is the reason why polarization of a transistor is done in such a way as to mitigate the influence of. 2N3055(NPN), MJ2955(PNP) Preferred Device Complementary Silicon Power Transistors Complementary silicon power transistors are designed for general−purpose switching and amplifier applications.

• Here is a very simple circuit that can b e used to check the hfe of transistors. Both PNP and NPN transistors can be checked using this circuit. Hfe as high as 1000 can be measured by using this circuit.The circuit is based on two constant current sources build around transistors Q1 and Q2.The Q1 is a PNP transistor and the constant current flows in the emitter lead
• Transistor Basics: The schematic representation of a transistor is shown to the left. Note the arrow pointing down towards the emitter. This signifies it's an NPN transistor (current flows in the direction of the arrow). See the datasheet at: www.fairchildsemi.com.

The 2N2218, 2N2219, 2N2221 and 2N2222 are silicon planar epitaxial NPN transistors in Jedec TO-39 (for 2N2218 and 2N2219) and in Jedec TO-18 (for 2N2221 and 2N2222) metal cases. They are designed for high-speed switching applications at collector currents up to 500 mA, and feature useful current gain over a wide range of collector current,low leakage currents and low saturation voltages You may notice NPN transistors are mostly used than PNP transistors in electronic circuits but why? There are so many important and useful advantages of NPN transistor, for which, they are widely used.
