This transistor features a low saturation voltage and high current gain, which ensures efficient amplification of audio signals. Its TO-247 package ensures efficient heat dissipation, making it a reliable choice for high-power amplification applications.
On the other hand, the 2SA1494 transistor is a PNP epitaxial planar silicon transistor complementary to the 2SC3858. Just like its counterpart, it boasts an impressive collector current rating of 15A and a collector-emitter voltage of 180V. The 2SA1494 exhibits low distortion characteristics and good frequency response, making it an ideal choice for audio amplifier applications. With its TO-247 package, it provides excellent thermal conductivity, ensuring reliable performance in high-power amplification circuits.
Moving on, the TIP31 transistor is a widely used NPN epitaxial silicon transistor that can deliver a maximum collector current of 3A and a collector-emitter voltage of 40V. It is primarily used in low to medium power amplifier circuits and other general-purpose applications. The TIP31 offers good linearity and low distortion, making it suitable for audio amplification tasks where moderate power levels are required.
The TIP32 transistor is the PNP complement to the TIP31, offering similar specifications but with reversed polarity. It can also handle a maximum collector current of 3A and a collector-emitter voltage of 40V. As a result, it is often used in combination with the TIP31 to form a complementary power amplifier output stage.
