Working Principles

The DG221BDY-T1-E3 is a Schottky diode that operates based on the principle of metal-semiconductor junction. It consists of a metal contact (anode) and a semiconductor material (cathode). When a forward voltage is applied, the metal-semiconductor junction allows for fast electron flow, resulting in low forward voltage drop. The absence of a P-N junction reduces the reverse recovery time, making it suitable for high-speed switching applications.
