R LL47 SMALL SIGNAL SCHOTTKY DIODES S E M I C O N D U C T O R FEATURES MiniMELF 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. This diode is also available in the DO-35 case with type designation BAT47. 0.063(1.6) 0.055(1.4) High temperature soldering guaranteed:260℃/10 seconds at terminals Component in accordance to RoHS 2002/95/EC and WEEE 2002/96/EC 0.019(0.48) 0.011(0.28) 0.142(3.6) 0.126(3.2) MECHANICAL DATA Case: MiniMELF glass case(SOD-80 ) Weight: Approx. 0.05 gram Dimensions in inches and (millimeters) ABSOLUTE RATINGS(LIMITING VALUES) Value Symbols Repetitive Peak Reverse Voltage Forward Continuous Current at TA=25 C Repetitive Peak Forward Current at tp <1s, d <0.5, Surge forward current at tp <10mS , Power Dissipation at TA=25 ℃ TA=25℃ TA=65℃ Junction temperature Ambient Operating temperature Range Storage Temperature Range Units V mA 20 VRRM IF IFRM IFSM Ptot TJ TA TSTG 1) 350 1 1) 7.5 330 A A mW 1) 1) 125 C C -65 to+125 -65 to+150 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 10mA Pulses Forward voltage Pulse Test tp< 300ms, d<2% at IF=0.1mA, at IF=10mA, at IF=300mA Min.
