| LL1.5 thru LL5.1 Vishay Semiconductors formerly General Semiconductor Voltage Stabilizers MiniMELF (SOD-80C) Cathode Mark 0.063 (1.6) 0.055 (1.4) 0.019 (0.48) 0.011 (0.28) 0.049(1.25) MIN Mounting Pad Layout 0.098(2.50) MAX 0.079(2.00) MIN 0.142 (3.6) 0.134 (3.4) Dimensions in inches and (millimeters) 0.197(5.00) REF Mechanical Data Case: MiniMELF Glass Case (SOD-80C) Weight: approx. 0.05g Cathode band color: Blue Packaging codes/options: D1/10K per 13" reel (8mm tape), 20K/box D2/2.5K per 7" reel (8mm tape), 20K/box Features * Silicon Planar Stabilizer Diodes * Monolithic integrated analog circuits in MiniMELF case, designed for small power stabilizer and limitation circuits, providing low dynamic resistance and high-quality stabilization performance as well as low noise. In the reverse direction, these devices show the behavior of forward-biased silicon diodes. * The end of the device marked with the cathode ring is to be connected: LL1.5 and LL2 to the negative pole of the supply voltage; LL2.4 thru LL5.1 to the positive pole of the supply voltage * These diodes are also available in DO-35 case with the type designation ZTE1.5 ...
