STMICROELECTRONICS TIP35C NPN Power Transistor, TO-247, 125W, 25A

The STMICROELECTRONICS TIP35C is a complementary power transistor designed for high-performance linear and switching applications. Engineered using planar technology with a unique 'base island' layout, it delivers exceptional DC current gain combined with very low saturation voltage, ensuring efficient operation under demanding conditions.

Housed in a robust TO-247 through-hole package, this transistor is built for reliability and ease of mounting. It offers a substantial 125W power dissipation rating, making it suitable for circuits handling significant power levels. Its 25A continuous collector current capability and 100V collector-emitter voltage rating provide the headroom needed for a wide range of industrial and commercial designs.

Key electrical characteristics include a collector-emitter saturation voltage of just 4V at the full 25A collector current, minimising power loss. The device maintains a DC current gain (hFE) of at least 10 at 15A, contributing to stable amplification. With an operating junction temperature up to 150°C, it is designed to perform reliably in environments with elevated thermal stress.

The transistor's 3MHz transition frequency makes it a versatile component suitable for audio amplifiers, power supplies, motor controllers, and other general-purpose applications where a robust, high-gain NPN device is required. Its through-hole construction ensures a secure mechanical and electrical connection on printed circuit boards.
