Description
The BC847CW is a general-purpose NPN bipolar junction transistor (BJT) in a SOT-323 package, part of the BC847 series. Key features:
- Low power: Suitable for small-signal amplification and switching.
- High current gain (hFE): Typically 420–800, ensuring efficient amplification.
- Voltage ratings: VCEO = 45V, IC = 100mA, making it ideal for low-voltage circuits.
- Compact size: SOT-323 package saves board space.
Common applications include audio amplification, signal processing, and digital logic switching. It is often paired with its PNP counterpart, BC857CW, in complementary circuits.
For optimal performance, ensure proper biasing and stay within specified limits (e.g., IC ≤ 100mA, Ptot ≤ 250mW). Check datasheets for detailed specs.
A concise, practical choice for low-power designs.
