Working Principle

The working principle of the DSC5501T0L transistor is based on the current control of the base-emitter junction. It is a three-terminal device consisting of a base, an emitter and a collector terminal. When the base-emitter junction is forward-biased, electrons from the emitter diffusion into the base and combine with electrons from the base. This process produces a current that flows from the emitter to the collector. When the base-emitter junction is reverse-biased, the current flow is blocked. By controlling the amount of current flow through the base-emitter junction, the amount of collector current can be regulated.
