SD101A THUR SD101C SMALL SIGNAL CHOTTKY DIODES SMALL SIGNAL SCHOTTKY DIODES S E M I C O N D U C T O R DO-35 FEATURES For general purpose applications The SD101 series is a Metal-on-silicon junction 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. These diodes are also available in the Mini-MELF case with the type designation LL101A to LL101C , in the SOD-123 case type with the type designation SD101AW to SW101CW, in the SOD-323 case type with the type designation SD101AWS to SW101CWS MECHANICAL DATA Case: DO-35 glass case Polarity: Color band denotes cathode end Weight: Approx. 0.05 gram Dimensions in inches and (millimeters) ABSOLUTE RATINGS(LIMITING VALUES) Value Symbols Peak Reverse Voltage VRRM VRRM VRRM Ptot IFSM TJ TSTG SD101A SD101B SD101C Power Dissipation (infinite Heat Sink) Maximum Single cycle surge 10ms square wave Junction temperature Storage Temperature Range Units 60 50 40 2.0 V V mW A 125 C 400 1) -55 to+150 C 1) Valid provided that leads at a distance of 4mm from case are kept at ambient temperature ELECTRICAL CHARACTERISTICS (Ratings at 25 C ambient temperature unless otherwise specified) Symbols Reverse breakover voltage at IR=10mA Leakage current at VR=50V VR=40V VR=30V Forward voltage drop at IF=1mA IF=15mA Junction Capacitance at VR=0V ,f=1MHz SD101A SD101B SD101C SD101A SD101B SD101C VR VR VR IR IR IR SD101A SD101B SD101C SD101A SD101B SD101C VF VF VF VF VF VF SD101A SD101B SD101C CJ CJ CJ Reverse Recovery time at IF=IR=5mA,recover to 0.1 IR Thermal resistance,junction to Ambient Min.
