2N2905 PNP Silicon Transistor

The 2N2905 is a widely used PNP silicon planar epitaxial transistor designed for general purpose switching and amplification applications. It is the PNP complement to the popular 2N2222 NPN transistor, making it ideal for complementary symmetry circuits and push-pull amplifier stages. This device is capable of handling medium currents and voltages, making it versatile for a variety of low-to-medium power electronic designs. The TO-39 metal can package offers superior heat dissipation and environmental protection compared to standard plastic packages, ensuring stable performance in professional and industrial equipment. Its fast switching characteristics and high frequency response also make it suitable for pulse-width modulation and digital logic interfacing.

Key Features:

Continuous collector current (IC) capability of -600 Milliamperes.

High DC current gain (hFE) typically ranging from 100 to 300.

High transition frequency (fT) of 200 Megahertz for high-speed switching.

Total power dissipation of 600 Milliwatts at ambient temperature.

Hermetically sealed TO-39 metal can package for high reliability.
