| LL1.5 THRU LL2.4 Voltage Stabilizers MiniMELF FEATURES Silicon Planar Stabilizer Diodes Monolithic integrated analog circuits in Min .063 (1.6) .055 (1.4) Cathode Mark .142 (3.6) .134 (3.4) .019 (0.48) .011 (0.28) iMELF 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 LL 2.4 to the positive pole of the supply voltage Dimensions in inches and (millimeters) These diodes are also available in DO-35 case with the type designation ZTE1.5 ... ZTE2.4. MECHANICAL DATA Case: MiniMELF Glass Case (SOD-80) Weight: approx. 0.05 g MAXIMUM RATINGS AND ELECTRICAL CHARACTERISTICS Ratings at 25 C ambient temperature unless otherwise specified Symbol Operating Current see Table "Characteristics" Inverse Current Power Dissipation at Tamb = 25 C Junction Temperature Storage Temperature Range 1) Valid Value Unit IF Ptot Tj TS 100 3001) 150 -55 to +150 mA mW C C provided that electrodes are kept at ambient temperature. 4/98 LL1.5 THRU LL2.4 ELECTRICAL CHARACTERISTICS Ratings at 25 C ambient temperature unless otherwise specified Symbol Forward Voltage at IF = 10 mA Temperature Coefficient of the stabilized voltage at IZ = 5 mA LL1.5, LL2 LL2.4 Thermal Resistance Junction to Ambient Air 1) Min. - - - - Typ. - -26 -34 - Max. 1.1 - - 0.41) Unit V 10-4/K 10-4/K K/mW VF VZ VZ RthJA Valid provided that electrodes are kept at ambient temperature.
