Features Mechanical Data * 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. * These diodes are also available in the DO-35 case with the type designations BAT42 to BAT43 and in the MiniMELF case with the type designations LL42 to LL43. Case: SOD-123 Plastic Package Weight: approx. 0.01g Marking Codes: BAT42W = L2 BAT43W = L3 Packaging Codes/Options: D3/10K per 13" reel (8mm tape), 30K/box D4/3K per 7" reel (8mm tape), 30K/box Maximum Ratings & Thermal Characteristics Ratings at 25C ambient temperature unless otherwise specified.
