Working Principles

The PMBT3904YS,115 is a small signal NPN transistor that operates by controlling the flow of current between its collector and emitter terminals through the application of a small current at its base terminal. When a positive voltage is applied to the base, it allows current to flow from the collector to the emitter, amplifying the input signal or enabling switching functions.

Detailed Application Field Plans

The PMBT3904YS,115 is commonly used in audio amplifiers, signal processing circuits, and low-power switching applications. Its high current gain and fast switching speed make it suitable for applications where small input signals need to control larger output currents with minimal distortion.
