Product Description
Product Overview
The DSB80C45HB is a preliminary, high-performance Schottky diode featuring common cathode configuration with low loss and soft recovery characteristics. It offers very low forward voltage (Vf), extremely low switching losses, and low reverse current (Irm) values, contributing to improved thermal behavior and reliable circuit operation. This diode is suitable for rectifiers in switch mode power supplies (SMPS) and as a free-wheeling diode in low voltage converters, enabling low voltage peaks for reduced protection circuits and low noise switching.
