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.
The BAT42W and BAT43W are Schottky diodes intended for general‑purpose applications. They offer very low forward voltage drop and fast switching, with a PN‑junction guard ring protecting against electrostatic discharge. The devices are available in SOD‑123, DO‑35, and MiniMELF packages.
Mechanical data show a SOD‑123 plastic case weighing about 0.01 g. Electrical characteristics include a repetitive peak reverse voltage of 30 V, forward continuous current of 200 mA, and a junction temperature rating of 125 °C. The datasheet also lists capacitance, leakage current, and reverse recovery time specifications.
