Product Overview
The CHAOHE MICROELECTRONICS CO., LTD. SD103AWS thru SD103CWS series are Schottky barrier diodes encapsulated in a small SOD-323 surface-mounted device (SMD) plastic package. These diodes are designed for general purpose switching applications and are ideally suited for automatic insertion. Key features include a low forward voltage drop, guard ring construction for transient protection, negligible reverse recovery time, and low capacitance. They are available in various reverse voltage ratings, making them versatile for a range of electronic designs.
