Description
B688 is – 120V, – 8A, Silicon PNP Power Transistor.
PNP transistors comprise the following key components:
PNP transistors control the flow of a large current (collector current) between the emitter and collector using a small current applied to the base (base current). When a base current flows, the PNP transistor permits the flow of electrons from the emitter to the collector, resulting in an increase in collector current. Reducing the base current reduces the collector current. Consequently, PNP transistors are valuable electronic components for controlling large output currents with small input currents.
