Schottky diodes are diodes with low forward voltage and fast switching characteristics. This document describes the features and mechanical data of BAT42W and BAT43W models, including dimensions, weight, and maximum ratings. These diodes have electrical characteristics such as reverse breakdown voltage, forward continuous current, and repetitive peak forward current. Additionally, they are protected by a PN junction guard ring to prevent damage from excessive voltage. These diodes are suitable for general purpose applications.
