2N2222 NPN BJT Transistor 0.8A 40V

The 2N2222 NPN bipolar junction transistor is a versatile component engineered for general-purpose amplification and switching tasks. Rated for a maximum collector current of 0.8A and a collector-emitter voltage up to 40V, it provides dependable performance across a wide range of low-to-moderate power circuits.

• Maximum collector current: 0.8A for reliable handling of moderate power loads.
• Collector-emitter voltage: up to 40V suitable for many common circuit designs.
• High transition frequency for effective high-speed switching and signal amplification.
• TO-18 metal can package that promotes heat dissipation and supports durable mounting.
• Consistent gain characteristics for predictable circuit behavior and repeatable results.

Built with optimized semiconductor materials and construction techniques, the 2N2222 reduces noise and improves switching speed relative to some earlier designs. The TO-18 metal can aids thermal management and allows straightforward PCB or through-hole mounting. These qualities make the 2N2222 well suited for switching applications, signal amplification, and driving small loads in both hobbyist and professional electronics projects.
