1. Overview of the STPS1H100AFN Diode\

The STPS1H100AFN is a high-voltage, ultra-fast recovery power Schottky diode manufactured by STMicroelectronics. With a forward voltage drop of 0.79V at 1A, it offers a low power dissipation solution in various electronic circuits. Its compact TO-220 package provides high thermal performance, making it suitable for both low and high-power applications.

2. Construction and Working Principle\

The STPS1H100AFN diode is constructed using a combination of metal and semiconductor materials. It consists of a metal anode and a semiconductor cathode, separated by a junction. The metal anode is typically made of tungsten or molybdenum, while the cathode is made of lightly doped n-type silicon. The junction between these two materials forms the barrier that controls the flow of current.
