TIP125 Darlington Transistor

The TIP125 is a silicon Epitaxial-Base PNP power transistor manufactured by STMicroelectronics using planar technology with a monolithic Darlington configuration. This component features very high DC current gain, making it suitable for driving heavy loads such as relays, motors, and solenoids. With a maximum collector-emitter voltage of 60V and a continuous collector current of 5A, it is robust enough for various industrial and hobbyist applications. The transistor comes in a standard TO-220 package, ensuring easy mounting and heat dissipation. Its complementary NPN counterpart is the TIP120, allowing for use in push-pull amplifier stages. Choose the TIP125 for reliable performance in low-frequency power switching and amplification circuits where high current gain is required.
