The 2N4238 is a high performance, low power, medium gain, NPN 3-pin through hole transistor. This transistor can be used for various amplification, switching or other electronic applications, where high gain performance is required. It is particularly suited for low noise audio preamplifiers, audio power amplifiers, amplifier stages for signals of all spectra and in industrial and consumer circuits.

The 2N4238 transistor is a member of the bipolar junction transistor (BJT) family. It has two PN junctions, the first one is between the emitter and collector, while the second one is between the base and collector. When a small forward base current is injected, it creates a larger collector current and hence a larger emitter current, resulting in amplification. This transistor is often used in small signal amplification stages. It is also very effective in switching applications, since it can provide very high switching speeds and low transition times.

The 2N4238 is a high performance, low power device, capable of handling up to 150mA of collector current, with a collector-emitter voltage of 90V. It has a typical maximum power dissipation of 500mW and a transition frequency of 300MHz. It has a low noise figure of 2.2dB at a gain of 10dB. The 2N4238 has an excellent common-mode rejection ratio of 68dB, making it suitable for applications where differential signals need to be amplified.

This transistor can handle a wide range of operating temperatures, from -65°C to 175°C. The 2N4238 also has an optimal gain-bandwidth product of 300MHz and a high voltage breakdown rating of 200V, making it suitable for use in high-voltage circuits. It also delivers outstanding performance in signal-to-noise ratios.

The 2N4238 is a perfect component for small signal amplification, signal switching and signal switching applications. This transistor has a low current gain of 15 and provides excellent signal fidelity. It is also a good choice for use in audio preamplifiers and amplifier stages, where high gain performance is required. It is also an ideal component for use in switch mode power supplies and converters.

In summary, the 2N4238 is an optimal choice for applications in which low power and high gain is required. Its small size, high transition frequencies and low noise figure makes it a great component for signal amplification and signal switching. Its excellent voltage breakdown and common-mode rejection capabilities make it suitable for use in high voltage and differential circuits. It is also a great component for use in audio preamplifiers and amplifier stages, where low noise and high performance isrequired. The 2N4238 is a reliable, high performance and cost-effective transistor.
