LL42, LL43 Schottky Diodes FEATURES MiniMELF ♦ For general purpose applications. Cathode Mark .142 (3.6) .134 (3.4) ∅ .063 (1.6) .055 (1.4) ♦ These diodes feature very low turn- .019 (0.48) .011 (0.28) on voltage and fast switching. These devices are protected by a PN junction guard ring against excessive voltage, such as electrostatic discharges. ♦ These diodes are also available in the DO-35 case with type designations BAT42 to BAT43 and in the SOD-123 case with type designations BAT42W to BAT43W.
