概要
Description
The BCX71J is a PNP bipolar junction transistor (BJT) designed for general-purpose amplification and switching applications. Key features include:
- Low voltage operation (max. -45V collector-emitter voltage).
- High current gain (hFE) of 100-630, ensuring efficient signal amplification.
- Low saturation voltage, making it suitable for switching circuits.
- Compact SOT-23 package, ideal for space-constrained designs.
Common uses include audio amplifiers, signal processing, and driver stages in low-power circuits. It is often paired with complementary NPN transistors (e.g., BCX70J) for push-pull configurations.
For optimal performance, ensure proper biasing and stay within -100mA collector current and 250mW power dissipation limits.
