2N3440 Transistor CDIL NPN Transistor 2N3440

Product Overview

The 2N3440 is a high-voltage, silicon NPN power transistor designed for linear amplification and high-voltage switching applications. It is particularly well-regarded for its performance in high-speed, high-voltage circuits, such as video output stages, gas discharge lamp drivers, and general-purpose power regulation. Housed in a durable TO-39 metal can package, it offers excellent thermal stability and reliability in demanding electronic environments.
