Working Principles

The PQ3DZ13U is an NPN silicon transistor that 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 function as a power switch or amplifier.
