| BAT42W, BAT43W Schottky Diodes FEATURES SOD-123 .022 (0.55) For general purpose applications These diodes feature very low turnon voltage and fast switching. These devices are protected by a PN junction guard ring against excessive voltage, such as electrostatic discharges. case with the type designations BAT42 to BAT43 and in the MiniMELF case with type designations LL42 to LL43.
