2N4401 is a type of NPN bipolar junction transistor (BJT) that is commonly used in electronic circuits for low-power amplification and switching applications. It has a maximum collector current rating of 600 mA and a maximum collector-emitter voltage rating of 40 V.
The 2N4401 transistor is housed in a TO-92 package, which is a small, three-pin package that is commonly used for low-power transistors. This package type is designed for easy installation and good thermal performance.
Transistors like the 2N4401 are used for a range of applications in electronic circuits, including amplification, switching, and voltage regulation. They are typically used in electronic devices and circuits that require low power consumption and compact size, such as in audio amplifiers, oscillators, and signal processing circuits.
