Summary Transistor – NPN (BC337)
This is the BC337, an NPN silicon BJT (Bipolar Junction Transistor). This little transistor can help in your project by being used to help drive large loads or amplifying or switching applications. The BC337 is specifically rated at 50V and 800mA max.
Note: The BC337 is a drop-in replacement for the P2N2222A Transistor
