Working Principles

The STSR3CD is an NPN silicon epitaxial planar transistor. It operates based on the principles of bipolar junction transistors (BJTs). When a small current flows into the base terminal, it controls a larger current flowing between the collector and emitter terminals. This amplification effect allows the transistor to switch and amplify signals.
