BAT42,BAT43 FEATURES SMALL SIGNAL CHOTTKY DIODES SMALL SIGNAL SCHOTTKY DIODES S E M I C O N D U C T O R DO-35 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) Value Symbols Repetitive Peak Reverse Voltage VRRM IF IFRM IFSM Ptot TJ TA TSTG Forward Continuous Current at TA=25 C Repetitive Peak Forward Current at tp Surge forward current at tp 1s, d 0.5, TA=25 C 10mS , TA=25 C 1) Power Dissipation at TA=65 C Junction temperature Ambient Operating temperature Range Storage Temperature Range Units V mA mA A mW 30 200 1) 500 4 200 1) 1) 1) 125 C -65 to+125 -65 to+150 C C 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% BAT42 BAT42 BAT43 BAT43 Leakage current pulse test tp 300ms ,d TJ=25 C; at VR=25V, TJ=100 C 2% at VR=25V, Min.
