2N2222 NPN Transistor
📄 Description:
The 2N2222 is a widely used, versatile NPN bipolar junction transistor (BJT) designed for general-purpose switching and amplification applications. It offers a good balance of gain, switching speed, and collector current capacity, making it suitable for small signal amplification, low-power switching, and interface circuits.
Typically housed in a TO-92 or TO-18 package, the 2N2222 can handle collector currents up to 800 mA and voltages up to 40 V. Its fast switching capabilities make it a preferred choice in digital logic circuits, relay drivers, and audio amplifiers.
🌟 Feature Description:
NPN transistor: Suitable for common emitter, common base, and common collector configurations.
High gain: Forward current gain (hFE) typically between 100 and 300.
Collector current (Ic): Maximum of 800 mA, allowing it to drive small loads.
Collector-Emitter voltage (Vce): Maximum 40 V, enabling operation at moderate voltages.
Fast switching: Suitable for high-speed switching applications.
Package types: Commonly available in TO-92 (plastic) and TO-18 (metal can) packages.
Applications: Signal amplification, switching loads, relay drivers, LED drivers, and low-power amplifiers.
