Product Description
Product Overview
The DSA120C150QB is a high-performance Schottky diode featuring common cathode configuration, low loss, and soft recovery characteristics. Designed for demanding applications, it offers very low forward voltage drop (Vf), extremely low switching losses, and low reverse current (Irm) values. Its improved thermal behavior and high reliability contribute to efficient circuit operation with reduced protection circuit requirements and low noise switching. This diode is ideal for rectifiers in switch mode power supplies (SMPS) and as a free-wheeling diode in low voltage converters.
