IC TT2140

 Meta Description of IC TT2140

The IC TT2140 is a high-voltage NPN silicon power transistor widely used in CRT television horizontal deflection output circuits and other high-speed switching applications. Designed for demanding electronic environments, this component is known for its excellent voltage endurance, fast switching speed, and long-term reliability, making it a trusted choice for TV repair technicians, electronics engineers, and industrial service professionals. It is specifically optimized for color TV horizontal output stages, where stable high-voltage pulse handling is essential.

Built with a triple diffused planar silicon structure, the TT2140 provides strong performance in circuits that require rapid switching with minimal loss. Its 800V collector-emitter voltage and 1500V collector-base breakdown voltage allow it to safely operate in high-voltage sections of televisions, monitors, and other display-related hardware. The built-in damper diode improves circuit protection and helps reduce voltage spikes, making the transistor highly efficient for horizontal scan circuits.
