L L 42 an d L L 43 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 DO-35 case with type designation BAT42 to BAT43. Mechanical Data Case: MiniMELF Glass Case (SOD-80) Weight: approx. 0.05g Cathode Band Color: Green Maximum Ratings and Thermal Characteristics (Ratings at 25oC ambient temperature unless otherwise specified.)
