LL103A-LL103C Small Signal Schottky Diodes VOLTAGE RANGE: 40 -- 20 V CURRENT: 400 mW Features For general purpose applications MINI-MELF Metal silicon schottky barrier device which is protected by a PN junction guard ring. The low forward voltage Cathode indification drop and fast switching make it ideal for protection of φ1 .5±0.1 MOS devices,steering,biasing and coupling diodes for fast switching and low logic level applications Mechanical Data 0.4±0.1 3.4 Case:JEDEC MINI-MELF +0.3 -0.1 Polarity: Color band denotes cathode end Weight: Approx. 0.031 gram Dimensions in millimeters ABSOLUTE RATINGS(LIMITING VALUES) Symbols LL103A LL103B LL103C UNITS Peak reverse voltage VRRM 40 30 20 V Pow er dissipation (Infinite Heat Sink) Ptot 4001) Single cycle surge 60Hz sine w ave I FSM 15 A Forward continuous current I(AV) 200 mA Junction tenperature TJ 125 TSTG -55 ---+ 150 Storage temperature range mW 1)Valid provided that leads at a distance of 4mm from case are kept at ambient temperature ELECTRICAL CHARACTERISTICS (Ratings at 25 ambient temperature unless otherw ise specified) Reverse breakdow n voltage @ IR=50 A LL103A LL103B LL103C Leakage current @ VR=50V LL103A,VR=30V LL103B,VR=20V LL103C,VR=10V Forw ard voltage drop @ I F=20mA I F=200mA Junction capacitance @ VR=0V,f=1MHz Reverse recovery time @ IF=IR=50mA to 200mA,recover to 0.1 IR Thermal resistance junction to ambient air http://www.luguang.cn Symbols Min.
