MOSPEC SK17-SK110 Surface Mount Schottky Barrier rectifiers SCHOTTKY BARRIER RECTIFIERS Using the Schottky Barrier principle with a Molybdenum barrier meta. These state-of-the-art geometry features epitaxial construction with oxide passivation and metal overlay contact. Ideally suited for low voltage, high frequency rectification, or as free wheeling and polarity protection diodes, in surface mount applications where compact size and weight are critical to the system. 1.0 AMPERES 100 VOLTS ＊Low Forward Voltage. ＊Low Switching noise. ＊High Current Capacity ＊Guarantee Reverse Avalanche. ＊Guard-Ring for Stress Protection. ＊Low Power Loss & High efficiency. ＊150℃ Operating Junction Temperature ＊Low Stored Charge Majority Carrier Conduction. ＊Plastic Material used Carries Underwriters Laboratory Flammability Classification 94V-O DO-214AC(SMA) ＊In compliance with EU RoHs 2002/95/EC directives MAXIMUM RATINGS Characteristic Peak Repetitive Reverse Voltage Working Peak Reverse Voltage DC Blocking Voltage RMS Reverse Voltage Average Rectifier Forward Current Non-Repetitive Peak Surge Current (Surge applied at rate load conditions halfware, single phase, 60Hz) Operating and Storage Junction Temperature Range Symbol SK17 SK18 SK19 SK110 Unit VRRM VRWM VR 70 80 90 100 V VR(RMS) 49 DIM 56 63 IO V 1.0 A 25 A -65 to +150 ℃ IFSM TJ , TSTG 70 A B C D E F G H MILLIMETERS MIN MAX 2.20 2.80 4.10 4.70 1.30 1.70 4.70 5.30 1.90 2.50 1.30 0.30 0.95 1.50 ELECTRIAL CHARACTERISTICS Characteristic Symbol Maximum Instantaneous Forward Voltage ( IF =1 Amp ) VF Maximum Instantaneous Reverse Current ( Rated DC Voltage, TC = 25℃ ) ( Rated DC Voltage, TC = 125℃ ) IR Maxmum Thermal Resistance Junction to case Typical Junction Capacitance ( Reverse Voltage of 4 volts & f=1 MHz ) SK17 SK18 0.75 RthjC CP SK19 70 SK110 0.85 Unit V 0.5 20 mA 60 ℃/W 60 PF CASE--Transfer molded plastic OLARITY--Cathode indicated polarity band SK17 Thru SK110 NSTANTANEOUS FORWARD CURRENT (Amp.)
