BAT42, BAT43
Schottky Diodes
DO-35
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.
max. Æ .079 (2.0)
Cathode
¨
These diodes are also available in the SOD-123
case with the type designations BAT42W to BAT43W
and in the MiniMELF case with type
designations LL42 to LL43.
