2N2904 PNP Silicon Transistor

The 2N2904 is a high-speed PNP silicon transistor designed for general-purpose switching and amplifier applications. It serves as the PNP complement to the NPN 2N2219. This device is particularly useful in circuits requiring fast switching times and low saturation voltages, such as pulse generators and logic-level shifting. The TO-39 metal can package provides excellent thermal stability and environmental protection, making it a preferred choice for high-reliability industrial equipment where standard plastic packages might not suffice. It is frequently used in driver stages and for switching loads up to 600 Milliamperes.

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.
