Product Description
Product Overview
The DSA70C100HB is a high-performance Schottky diode featuring low loss and soft recovery characteristics. Designed for demanding applications, this common cathode diode offers very low forward voltage (Vf), extremely low switching losses, and reduced reverse current (Irm) values. Its improved thermal behavior and high reliability contribute to efficient circuit operation with low voltage peaks, minimizing the need for extensive protection circuits and enabling low noise switching. It is ideal for use as rectifiers in switch mode power supplies (SMPS) and as free-wheeling diodes in low voltage converters.
