| LL42, LL43 Schottky Diodes MiniMELF FEATURES For general purpose applications. These diodes feature very low turn .063 (1.6) .055 (1.4) Cathode Mark on voltage and fast switching. These devices are protected by a PN junction guard ring against excessive voltage, such as electrostatic discharges. with type designations BAT42 to BAT43 and in the SOD-123 case with type designations BAT42W to BAT43W. .142 (3.6) .134 (3.4) .019 (0.48) .011 (0.28) These diodes are also available in the DO-35 case Dimensions in inches and (millimeters) 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 Repetitive Peak Reverse Voltage Forward Continuous Current at Tamb = 25 C Repetitive Peak Forward Current at tp < 1 s, < 0.5, Tamb = 25 C Surge Forward Current at tp < 10 ms, Tamb = 25 C Power Dissipation at Tamb = 65 C Junction Temperature Ambient Operating Temperature Range Storage Temperature Range 1) Value 30 2001) 5001) 41) 2001) 125 -55 to +125 -65 to +150 Unit V mA mA A mW C C C V RRM IF IFRM IFSM Ptot Tj Tamb TS Valid provided that electrodes are kept at ambient temperature. 4/98 LL42, LL43 ELECTRICAL CHARACTERISTICS Ratings at 25 C ambient temperature unless otherwise specified Symbol Reverse Breakdown Voltage tested with 100 A Pulses Forward Voltage Pulse Test tp < 300 s, < 2% at IF = 200 mA at IF = 10 mA at IF = 50 mA at IF = 2 mA at IF = 15mA Leakage Current Pulse Test tp < 300 s, < 2% at VR = 25 V at VR = 25 V, Tj = 100 C Capacitance at VR = 1 V, f = 1 MHz Reverse Recovery Time from IF = 10 mA through IR = 10 mA to IR = 1 mA, RL = 100 Rectification Efficiency at RL = 15 K, CL = 300 pF, f = 45 MHz, VRF = 2 V Thermal Resistance Junction to Ambient Air 1) Min. 30 Typ. - Max. - Unit V V(BR)R LL42 LL42 LL43 LL43 VF VF VF VF VF - - - 0.26 - - - - - - 1 0.4 0.65 0.33 0.45 V V V V V IR IR Ctot trr - - - - - - 7 - 0.5 100 - 5 A A pF ns v 80 - - % RthJA - - 0.31) K/mW Valid provided that electrodes are kept at ambient temperature. |
