TIP142 10A 100V NPN Bipolar Power Transistor
The TIP142 is a NPN bipolar power transistor with a maximum collector current rating of 10A and a maximum collector-emitter voltage rating of 100V. It is commonly used in power amplification and switching applications, such as in audio amplifiers, power supplies, and motor control circuits. The TIP142 has a complementary PNP counterpart, the TIP147, and is often used in complementary pair configurations for increased power handling capabilities. The TIP142 is packaged in the TO-220 package, which is a commonly used package for power transistors.
Description
The TIP142 is a type of bipolar power transistor that is commonly used in electronic circuits for amplification and switching purposes. It is an NPN (Negative-Positive-Negative) type transistor, meaning that current flows from the collector to the emitter when a voltage is applied to the base.
The TIP142 has a maximum collector current rating of 10A, which means that it can handle a maximum current of 10 amps in the collector circuit. It also has a maximum collector-emitter voltage rating of 100V, which specifies the maximum voltage that can be applied between the collector and emitter terminals.
The TIP142 is commonly used in power amplifier circuits, power supplies, and motor control circuits, among other applications. Its compact TO-220 (COM24) package and high current and voltage ratings make it a popular choice for a wide range of power electronics applications.
It is also worth noting that the TIP142 has a complementary PNP transistor, the TIP147, which can be used in conjunction with the TIP142 to create complementary bipolar transistor pairs for increased power handling capabilities in circuits.
