C2271

The C2271 is a dependable NPN transistor engineered for electronic switching and amplification tasks where consistent performance and thermal stability are required. It combines a robust current capability with moderate voltage tolerance to meet the needs of a wide array of circuits, from signal amplification to power switching. Collector-Emitter Voltage (Vce): 60V — suitable for medium-voltage applications. Collector Current (Ic): 3A — supports substantial load currents for demanding circuits. Power Dissipation: 15W — enables efficient heat handling during sustained operation. Gain (hFE): 40–320 — offers a broad amplification range for flexible circuit design. Transition Frequency (ft): 100 MHz — allows effective switching and response at high frequencies. Designed with attention to thermal management and manufacturing consistency, the C2271 minimizes thermal resistance and maintains reliable operation under continuous use. Its construction and material choices aim to reduce performance drift across temperature variations, supporting predictable behavior in both hobbyist and professional applications. Functionally, the transistor is well suited to roles where a balance of current capacity, power dissipation, and frequency response is important. Typical uses include switching stages in power control circuits, driver stages for relays or motors with moderate current demands, and amplification stages where a versatile gain range is beneficial. Its combination of characteristics makes it a practical option when designers require a single transistor solution that can accommodate multiple circuit requirements without frequent substitution. When selecting the C2271, consider its specified voltage, current, and dissipation limits to ensure safe operating margins and adequate heat sinking for sustained loads.
