BAT42 - BAT43 SCHOTTKY BARRIER 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 electro-static
discharges
• These diodes are also available in the MiniMELF case
with the type designations LL42 to LL43.
• Pb / RoHS Free
