The BC337 is an NPN Transistor commonly used in low power amplifier circuits. The Transistor can provide a maximum gain (hfe) of 630. 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.
The transistor also has a high collector current of up to 800mA and a decent collector-emitter voltage of 45V and the base trigger voltage is only 5V. This makes the transistor suitable to be used in general-purpose switching circuits. Due to its low base trigger voltage, it can be easily controlled by digital circuits like microcontroller circuits. So, if you are looking for a transistor for audio amplification then you might consider the BC337. Also, look into the more commonly used 2N2222 Transistor if you are looking for a replacement for BC337 to switch loads.
