Product Description
Product Overview
The DSS2x121-0045B is a high-performance Schottky Diode designed for applications requiring low loss and soft recovery. It features parallel legs for enhanced performance and comes in a SOT-227B (minibloc) package with an industry-standard outline. Key advantages include very low forward voltage (Vf), extremely low switching losses, low reverse recovery current (Irm) values, and improved thermal behavior for high reliability circuit operation. This diode is suitable for rectifiers in switch mode power supplies (SMPS) and as a free-wheeling diode in low voltage converters.
