BAT 42 BAT 43 are small signal Schottky diodes featuring very low turn-on voltage and fast switching. These devices have integrated protection against excessive voltage such as electrostatic discharges.
This document provides technical specifications for the BAT 42 and BAT 43, which are general-purpose, metal-to-silicon Schottky diodes. These devices are designed for applications requiring very low turn-on voltage and fast switching speeds. They are housed in a DO-35 glass package and include integrated protection against excessive voltage, such as electrostatic discharges.
The datasheet details absolute ratings, including a repetitive peak reverse voltage of 30 V and a forward continuous current of 200 mA. It also lists electrical characteristics for static and dynamic parameters, such as forward voltage drop and switching time, along with thermal resistance and package mechanical dimensions.
