Description

The BC847BW 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 200–450, ensuring efficient amplification.
- Voltage ratings: VCEO = 45V, IC = 100mA, making it ideal for low-voltage circuits.
- Dual-emitter structure: Unique to the "W" variant, enabling compact designs in space-constrained applications.
Common uses include audio amplification, signal processing, and digital logic circuits. Its small size and reliability make it popular in consumer electronics and embedded systems.
For detailed specs, refer to the datasheet from manufacturers like NXP, ON Semiconductor, or Diodes Inc.
