Silicon Schottky diode rectifiers produce very low forward voltage drops while serving as ac switches in power converts and switched-mode power supplies.With its low reverse leakage current and high reliability, this diode is perfect for use in power supplies, DC-DC converters, solar systems, and communication devices.
Zener diodes are specially designed semiconductor devices that allow current to flow not only in the forward direction like a standard diode, but also in the reverse direction when the voltage exceeds a specific value—known as the Zener breakdown voltage. They are widely used for voltage regulation, overvoltage protection, and reference voltage generation in electronic circuits.
Rectifier diodes are fundamental semiconductor devices used to convert alternating current (AC) into direct current (DC).They play a crucial role in power supplies, converters, and various electronic circuits where stable DC voltage is required.With their ability to handle high current and voltage, Prosemi rectifier diodes ensure reliable performance and long-term stability in demanding applications.
