BYV10 Schottky Barrier Diode Series

Overview

The BYV10-20 to BYV10-40 series are high-performance Schottky barrier diodes designed for applications requiring low switching losses and fast recovery times. These diodes are fabricated using planar technology and are encapsulated in a hermetically sealed SOD81 glass package, ensuring reliability and durability in demanding environments. The Schottky barrier construction provides superior switching performance compared to conventional PN-junction diodes, making the BYV10 series ideal for high-frequency and high-efficiency applications.

The BYV10 series is particularly well-suited for power supply circuits, reverse polarity protection, and freewheeling diode applications. The guard ring protection feature enhances the diode's robustness against voltage transients, while the hermetically sealed glass package provides excellent environmental protection.
