The BC337-25 is a general purpose NPN silicon BJT (Bipolar Junction Transistor) commonly used in low power amplifier circuits. This little transistor can help in your project by being used to help drive large loads like driving a relay for example. It can also be used in amplifying or switching applications. The BC337 is specifically rated at 45V and 800mA max and the base trigger voltage is only 5V.

The BC337 has three part names, the gain value of BC337-16 is 100 to 250, for BC337-25 it is 160 to 400 and for BC337-40 it is 250 to 630. Apart from the gain value other parameters are similar for all the three part numbers


  • Low power audio amplifiers
  • Small signal amplifiers
  • Audio frequency Driver
  • Amplifier Output Stage
  • General purpose switching

Also look into the more commonly used 2N2222 Transistor if you are looking for a replacement for BC337 to switch loads
