Power Transistors

Power transistors play a key role in various electronic circuits and devices. Here's what these components are used for: TIP31C, TIP41C, TIP42C - These are high-power medium-power bipolar transistors. TIP31C and TIP41C are NPN transistors, and TIP42C is a PNP transistor. They are often used in audio amplifiers, switching devices, and general power control applications. D882 (NPN) and B772 (PNP) - These transistors are commonly used as a pair to create push-pull audio amplifiers that require both positive and negative current control. TDA2030A is an audio amplifier IC capable of delivering up to 18W of power into a 4 ohm load. It is used to create inexpensive but effective audio amplifiers in home audio, televisions and other audio equipment. IRF540N - N-type power field-effect transistor (MOSFET), used in applications where large currents need to be controlled, such as power supplies, LED drivers and motor controllers. L7805CV and L7809CV - These are linear voltage regulators that provide constant output voltages of 5 V and 9 V respectively. Used in a variety of power supply voltage regulation applications to provide reliable and stable power to electronic devices. These components are often found in power supplies, amplifiers, voltage regulators, and other high-power applications that require handling large currents and power. Each component is selected based on its characteristics, such as maximum current, voltage and power, to meet the specific requirements of the application.
