    Products Detail

    TIP142 – STMicroelectronics NPN Power Darlington Transistor

    Product Overview

    The TIP142 is a NPN power Darlington transistor manufactured by STMicroelectronics. It is designed for high-current amplification and power switching applications, combining two bipolar transistors in a monolithic Darlington configuration to achieve very high current gain.

    This device is widely used in audio power amplifiers, motor drivers, power regulators, and industrial switching systems, where high gain and high current capability are required.

    STMicroelectronics describes the TIP142 as a silicon epitaxial-base NPN Darlington transistor in a TO-218 / TO-247 power package, intended for linear and switching industrial applications, with high current handling and integrated protection structure.
