Working Principles

The TD350ETR is an NPN bipolar junction transistor that operates based on the principles of amplification and control of electrical signals. When a small input current is applied to the base pin, the transistor amplifies it and produces a larger output current at the collector pin. This amplification is achieved through the control of charge carriers within the transistor's semiconductor material.
