Review AMPEREX Lot Complementary Pair Npn Pnp Transistors Matched

The 2N4105 and 2N4106 are a pair of complementary NPN transistors manufactured by Amperex, a reputable semiconductor manufacturer. These transistors are widely used in various electronic circuits due to their excellent electrical characteristics and reliability.

The 2N4105 is a general-purpose NPN transistor that exhibits a high current gain (h Fe) of around 100, ensuring efficient amplification of input signals. It has a maximum collector-emitter voltage (VCEo) of 45V, making it suitable for use in high voltage applications. The 2N4105 also features a low collector-emitter saturation voltage (VCEsat) of about 0.2V, ensuring minimal power loss during operation.

On the other hand, the 2N4106 is a companion transistor to the 2N4105, serving as its PNP counterpart in complementary amplifier circuits. The 2N4106 has a similar current gain (h Fe) of around 100 and a maximum collector-emitter voltage (VCEo) of 45V. Its collector-emitter saturation voltage (VCEsat) is also comparable to the 2N4105, at about 0.2V.

Both the 2N4105 and 2N4106 transistors have a maximum collector current (Ic) of 2.5A, ensuring they can handle moderate power levels. They also feature a low collector-base junction leakage current (Icb), which ensures minimal leakage and improves circuit stability.

In summary, the 2N4105 and 2N4106 are a pair of high-quality, general-purpose NPN and PNP transistors, respectively. Their excellent electrical characteristics, including high current gain, low saturation voltage, and high maximum collector current, make them suitable for various electronic applications, including amplifier circuits, switch-mode power supplies, and voltage regulators.
