2N2405 NPN Silicon Transistor

The 2N2405 is an NPN silicon planar epitaxial transistor designed for high-voltage general purpose switching and amplification applications. It is particularly well-suited for industrial and military environments where durability and reliability are paramount. With a collector-emitter voltage of 90 Volts and a current capacity of 1.0 Ampere, it is a robust choice for driving relays, lamps, or small motors. The device also serves effectively as a high-speed switch or as an amplifier in frequency ranges up to 120 Megahertz. Its TO-39 metal can package provides excellent environmental protection and superior thermal stability compared to standard plastic housings. This makes the 2N2405 a dependable component for professional-grade power supplies and signal processing equipment.

Key Features:

Continuous collector current (IC) capability of 1.0 Ampere.

Total power dissipation of 1.0 Watt at ambient temperature.

DC current gain (hFE) typically ranging between 40 and 120.

High transition frequency (fT) of 120 Megahertz.

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