Working Principles

The LCS701HG is a bipolar junction transistor (BJT) that operates based on the principles of amplification and control of electric current. It consists of three layers of semiconductor material, namely the emitter, base, and collector. By applying a small current to the base terminal, the transistor can control a larger current flowing between the collector and emitter terminals. This amplification capability makes it suitable for signal amplification applications.
