2N2222 NPN Transistor

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.
