BAT48 Small-Signal Diode Schottky Diode 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 MiniMELF case with type designation LL48. Mechanical Data Case: DO-35 Glass Case Weight: approx. 0.13g Maximum Ratings and Thermal Characteristics (Ratings at 25oC ambient temperature unless otherwise specified.)
