The BC547 Transistor (Pack of 5 Pieces) is a general-purpose NPN bipolar junction transistor for switching and amplification. It is the most commonly used transistor in hobby electronics for low-power switching and signal amplification.
Key features
- NPN BJT transistor
- General purpose switching and amplification
- Low power (100mA max collector current)
- TO-92 package
- High DC current gain (hFE: 110-800)
- Low cost
- Pack of 5 pieces
Good to know
- Pinout (front face): C-B-E (Collector-Base-Emitter)
- Do not exceed max ratings – will damage transistor
- Use base resistor to limit base current
- Saturated switch: IB ≥ IC(sat) / 10
- Heat sink not needed for low current (<100mA)
