2N5401 is a PNP Transistor specifically designed to be used in high voltage applications where load consumes very less power (i.e. Current drawn by the load is low). These types of circuits can be seen in telephone systems. It can also be used when you want a simple switching device for high voltage loads. Also, the component is cheap and easy to work with.
