| BAT42,BAT43 SEMICONDUCTOR SMALL SIGNAL SCHOTTKY DIODES DO-35 SMALL SIGNAL CHOTTKY DIODES WWW.JIFUSEMICON.COM FEATURES For general purpose applications These diodes features 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. These diodes are also available in the Mini-MELF case with type designation LL42 to LL43and in the SOD-123 case with the type designation BAT42W to BAT43W,in the Micro-MELF case with type designation MCL42 to MCL43 MECHANICAL DATA Case: DO-35 glass case Polarity:color band denotes cathode end Weight: Approx. 0.13 gram Dimensions in inches and (millimeters) ABSOLUTE RATINGS(LIMITING VALUES) Symbols Repetitive Peak Reverse Voltage Forward Continuous Current at TA=25 C Repetitive Peak Forward Current at tp Surge forward current at tp 1) Value 30 200 500 4 200 125 -65 to+125 -65 to+150 1) 1) 1) 1) Units V mA mA A mW C C C 1s, d 0.5, TA=25 C 10mS , TA=25 C Power Dissipation at TA=65 C Junction temperature Ambient Operating temperature Range Storage Temperature Range VRRM IF IFRM IFSM Ptot TJ TA TSTG 1) Valid provided that leads at a distance of 4mm from case are kept at ambient temperature ELECTRICAL CHARACTERISTICS Symbols Reverse breakdown voltage Tested with 100mA Pulses Forward voltage Pulse Test tp at IF=200mA, atIF=10mA, atIF=50mA, at IF=2mA , atIF=15mA, 300ms,d 2% Min. 30 1 0.4 0.65 0.33 0.45 0.5 100 7 5 300 1) Typ.
