BAT45 Small Signal Schottky Diodes VOLTAGE RANGE: 15 V CURRENT: 30 mA Features DO - 35(GLASS) For general purpose applications Metal silicon schottky barrier device which is protected by a PN junction guard ring. The low forward voltage drop and fast switching make it ideal for protection of MOS devices,steering,biasing and coupling diodes for fast switching and low logic level applications Mechanical Data Case:JEDEC DO--35,glass case Dimensions in millimeters Polarity: Color band denotes cathode end Weight: Approx. 0.13 gram ABSOLUTE RATINGS(LIMITING VALUES) Peak reverse voltage Symbols Value UNITS VRRM 15 V 301) mA IFSM 60 mA TJ -65 ---+ 150 TSTG c-65 ---+ 150 IF Forward continuous current Surge non repetitive forward current tp≤1s Junction tenperature Storage temperature range 1)Valid provided that electrodes are kept at ambient temperature.
