BC337 Transistor

Type: NPN (Negative-Positive-Negative) transistor: In NPN transistors like the BC337, current flows from the collector (C) to the emitter (E) when a small current is applied to the base (B).

Polarity: The BC337 is an NPN transistor, which means it amplifies or switches electronic signals with a positive voltage at the collector relative to the emitter.

Amplification: The BC337 has a moderate gain, typically ranging from 100 to 800. This makes it suitable for amplification purposes in small-signal applications.

Voltage Ratings: The transistor is often rated for a maximum collector-emitter voltage (VCEO) of around 45 to 50 volts and a collector current (IC) of up to 800 mA.

Package Type: The BC337 is typically available in a TO-92 package, which is a small, three-lead plastic package that is easy to handle and mount on a PCB.
