Description
The BCW71 is 45V, 100mA, NPN General Purpose Transistor in a SOT23 plastic package. PNP complements: BCW69 and BCW70.
A NPN transistor is a type of bipolar junction transistor (BJT) that consists of two n-type semiconductor materials separated by a single p-type material.
The NPN transistor is used to amplify or switch electronic signals and is widely used in many electronic circuits. It works by controlling the current flow between the collector and emitter terminals through the base terminal.
When a small current is applied to the base, it controls a much larger current between the collector and emitter, making the NPN transistor an effective amplifier or switch.
