BAT42 and BAT43 Small-Signal Diode Schottky Diodes Features For general purpose applications. These diodes feature very low turn-on voltage and fast switching. These devices are protected by a PN junction guard ring against excessive voltage, such as electrostatic discharges This diode is also available in the MiniMELF case with type designation LL42 to LL43.
