概要
Description
- Current/Voltage Ratings: Max collector current (Ic) of 100mA, collector-emitter voltage (Vce) of 65V.
- Gain (hFE): 110–450 (at 2mA Ic), ensuring good signal amplification.
- Low Noise: Suitable for analog signal processing.
- High Speed: Transition frequency (fT) of 100MHz, useful for RF and fast switching.
It’s often paired with its PNP counterpart (BC856A) in complementary circuits. Typical applications include audio preamps, signal amplification, and digital logic switching.
Advantages: Compact size, cost-effective, and widely available.
Limitations: Not suited for high-power or high-voltage scenarios.
For detailed specs, refer to the datasheet.
