| BL FEATURES GALAXY ELECTRICAL VOLTAGE RANGE: 30 V CURRENT: 0.2 A BAT85 SMALL SIGNAL SCHOTTKY DIODES For general purpose applications This diode 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 DO - 35(GLASS) MECHANICAL DATA Case:JEDEC DO--35,glass case Polarity: Color band denotes cathode end Weight: Approx. 0.13 gram ABSOLUTE RATINGS Symbols Continuous reverse voltage Forw ard continuous current Peak forw ard current Surge forw ard current Pow er dissipation Junction temperature Ambient operating temperature range Storage temperature range @ @ @ TA=25 TA =25 tp<1s,TA=25 Value 30.0 200 300 600 200 1) 1) 1) 1) UNITS V mA mA mA mW VR IF IFM IFSM P tot TJ TA TSTG @ TA=65 125 c-55 ---+ 125 c-55 ---+ 150 1) Valid provided that leads at a distance of 4mm from case are kept at ambient temperature ELECTRICAL CHARACTERISTICS Symbols Reverse breakdow n voltage Forw ard voltage Pulse test tp<300 s, <2% @ IF=0.1mA @ IF=1mA @ IF=10mA @ IF=30mA @ IF=100mA Leakage current V R=25V Junction capacitance at V R=1V,f=1MHz Reverse recovery time @ IF=10mA,IR=10mA,IR=1mA Thermal resistance junction to ambient Min. 30.0 Typ.
