Introduction
The TIP49 is a high-power NPN transistor designed for use in linear and switching applications. It is widely used in power amplifiers, voltage regulators, and power supply circuits due to its high voltage and current handling capability. With a collector-emitter voltage of 250V and a continuous collector current of 1A, the TIP49 is a robust choice for medium to high power applications in both industrial and consumer electronics.

PNP Complementary Transistor
PNP Complementary of TIP49 Transistor is TIP42C.
- TIP42C (PNP Complement of TIP49)
(Both share similar current rating, package type (TO-220), and complementary electrical characteristics, but one is NPN and the other is PNP.)
If you’re building a circuit that requires a complementary PNP to match the TIP49’s high-voltage capability, TIP42C is the commonly recommended choice.
