Description:
The BC549 is a low-noise NPN bipolar junction transistor (BJT) designed for sensitive signal amplification and switching applications. It is widely used in audio preamplifiers, microphone circuits, and precision analog designs where low noise and stable performance are important.

Specifications:

  • Type: NPN BJT Transistor
  • Collector-Emitter Voltage (Vce): 30V
  • Collector-Base Voltage (Vcb): 30V
  • Emitter-Base Voltage (Veb): 5V
  • Continuous Collector Current (Ic): up to 100mA
  • Power Dissipation: ~500mW
  • Current Gain (hFE): 110 – 800 (A/B/C variants)
  • Noise Figure: Low (ideal for audio applications)
  • Transition Frequency: ~150 MHz
  • Package: TO-92

Features:

  • Low-noise transistor suitable for audio circuits
  • High current gain options available
  • Compact TO-92 package
  • Stable and reliable performance
  • Widely used in analog electronics

Applications:

  • Audio preamplifiers
  • Microphone amplifiers
  • Signal amplification
  • Switching circuits
  • Analog and embedded systems

Pin Configuration (Flat side facing you):

  • Collector (C)
  • Base (B)
  • Emitter (E)

Important Note:

  • Suitable for low current applications only (≤100mA)
  • Use a base resistor to limit current
  • Not suitable for high-power loads

Package Includes:

  • 1 × BC549 Transistor
