Product details of BC548 - NPN Transistor(10pcs)

  • Bi-Polar NPN Transistor
  • DC Current Gain (hFE) is 800 maximum
  • Continuous Collector current (IC) is 500mA
  • Emitter Base Voltage (VBE) is 5V
  • Base Current(IB) is 5mA maximum

Description of BC548

BC548 is a NPN transistor so the collector and emitter will be left open (Reverse biased) when the base pin is held at ground and will be closed (Forward biased) when a signal is provided to base pin.BC548 has a gain value of 110 to 800, this value determines the amplification capacity of the transistor. The maximum amount of current that could flow through the Collector pin is 500mA, hence we cannot connect loads that consume more than 500mA using this transistor. To bias a transistor we have to supply current to base pin, this current (IB) should be limited to 5mA.
